Bringing such systems far from equilibrium, however, can drastically enhance mode-to-mode interactions. Understanding the resulting liquid is a fundamental question for quantum statistical mechanics and a practical question for engineering driven quantum devices. To tackle this question, we probe the non-equilibrium kinetics of one-dimensional plasmons in a long chain of Josephson junctions. We introduce multimode spectroscopy to controllably study the departure from equilibrium, witnessing the evolution from pairwise coupling between plasma modes at weak driving to dramatic, high-order, cascaded couplings at strong driving. Scaling to many-mode drives, we stimulate interactions between hundreds of modes, resulting in near-continuum internal dynamics. Imaging the resulting non-equilibrium plasmon populations, we then resolve the nonlocal redistribution of energy in the response to a weak perturbation—an explicit verification of the emergence of a strongly interacting, non-equilibrium liquid of plasmons."}],"_id":"21340","intvolume":"        12","file":[{"file_name":"2026_ScienceAdv_Bubis.pdf","relation":"main_file","access_level":"open_access","date_updated":"2026-02-24T07:23:32Z","file_id":"21353","file_size":2775975,"success":1,"date_created":"2026-02-24T07:23:32Z","content_type":"application/pdf","creator":"dernst","checksum":"8402f322f8f0e858b1d9aac57e306e31"}],"department":[{"_id":"MaSe"},{"_id":"AnHi"},{"_id":"GeKa"}],"publication":"Science Advances","volume":12,"DOAJ_listed":"1","OA_place":"publisher","year":"2026","author":[{"first_name":"Anton","full_name":"Bubis, Anton","id":"1f6212b5-f795-11ec-9c0c-de4780302890","last_name":"Bubis"},{"first_name":"Lucia","full_name":"Vigliotti, Lucia","id":"539e1e1a-e604-11ee-a1df-f02b018e5c8c","last_name":"Vigliotti"},{"orcid":"0000-0002-2399-5827","last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","full_name":"Serbyn, Maksym"},{"first_name":"Andrew P","full_name":"Higginbotham, Andrew P","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","last_name":"Higginbotham","orcid":"0000-0003-2607-2363"}],"oa_version":"Published Version","article_processing_charge":"Yes","title":"Non-equilibrium plasmon liquid in a Josephson junction chain","arxiv":1,"publisher":"American Association for the Advancement of Science","publication_status":"published","date_created":"2026-02-22T20:47:38Z","status":"public","acknowledgement":"We thank V.

To address this, an analytical workflow is introduced for the holistic characterization, modelling, and simulation of device heterostructures. This workflow automates the experimental (S)TEM data analysis, providing an in-depth characterization of crystallographic information, 3D orientation, elemental composition, and strain distribution. It reduces a process that typically takes days for a trained human into an automatic routine solved in minutes. Utilizing a physics-guided artificial intelligence model, it generates representative descriptions of materials and samples. The workflow culminates in creating digital twins of systems limited with at least one axis of translational invariance –3D finite element and atomic models of millions of atoms–enabling simulations that provide crucial insights into device behavior in practical applications. Demonstrated with SiGe planar heterostructures for scalable spin qubits, the workflow links digital twins to theoretical properties, revealing how atomic structure impacts materials and functional properties such as spatially-resolved phononic or electronic characteristics, or (inverse) spin orbit lengths. The versatility of the workflow is demonstrated through its application to a wide array of materials systems, device configurations, and sample morphologies.","lang":"eng"}],"_id":"20594","publication":"Advanced Materials","department":[{"_id":"GeKa"}],"date_updated":"2025-12-01T15:12:53Z","external_id":{"isi":["001597428400001"],"arxiv":["2411.01024"]},"oa":1,"tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"has_accepted_license":"1","doi":"10.1002/adma.202506785","publication_identifier":{"eissn":["1521-4095"],"issn":["0935-9648"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/adma.202506785"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"e06785","citation":{"ama":"Botifoll M, Pinto-Huguet I, Rotunno E, et al.

Individual tunneling events are used as the clock’s ticks. We quantify the clock’s precision while measuring the power dissipated by the DQD and, separately, the charge sensor in both direct-current and radio-frequency readout modes. This allows us to probe the thermodynamic cost of creating ticks microscopically and recording them macroscopically. Our experiment is the first to explore the interplay between the entropy produced by a microscopic clockwork and its macroscopic measurement apparatus. We show that the latter contribution not only dwarfs the former but also unlocks greatly increased precision, because the measurement record can be exploited to optimally estimate time even when the DQD is at equilibrium. Our results suggest that the entropy produced by the amplification and measurement of a clock’s ticks, which has often been ignored in the literature, is the most important and fundamental thermodynamic cost of timekeeping at the quantum scale.","lang":"eng"}],"intvolume":"       135","file":[{"checksum":"e5c89b95d0f52a38f2d2ada3483f3576","creator":"dernst","file_size":444198,"success":1,"date_created":"2025-12-01T08:28:00Z","content_type":"application/pdf","file_id":"20718","date_updated":"2025-12-01T08:28:00Z","access_level":"open_access","relation":"main_file","file_name":"2025_PhysReviewLetters_Wadhia.pdf"}],"month":"11","article_type":"original","PlanS_conform":"1","OA_type":"hybrid","quality_controlled":"1","file_date_updated":"2025-12-01T08:28:00Z","citation":{"apa":"Wadhia, V., Meier, F., Fedele, F., Silva, R., Nurgalieva, N., Craig, D.

However, the scalability potential of this readout technique can only be leveraged if quantum device tuning is performed using exclusively radio-frequency measurements, that is, without resorting to current measurements. We demonstrate an algorithm that performs automatic coarse tuning of double quantum dots with only radio-frequency measurements by exploiting their bandwidth and impedance matching. The tuning was completed within a few minutes with minimal prior knowledge about the device. Our results show that it is possible to eliminate the need for transport measurements for quantum-dot tuning, paving the way for more scalable device architectures.","lang":"eng"}],"intvolume":"        24","publication":"Physical Review Applied","department":[{"_id":"GeKa"}],"volume":24},{"quality_controlled":"1","PlanS_conform":"1","OA_type":"gold","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Aggarwal K, Rolandi A, Yang Y, et al.

Efficient work extraction for fast-driving protocols remains an outstanding challenge at the nanoscale, where fluctuations play a significant role. In this Letter, we use a quantum-dot Szilard engine to extract work from thermal fluctuations with maximum efficiency over two decades of driving speed. We design and implement a family of optimized protocols ranging from the slow- to the fast-driving regime, and we measure the engine's efficiency as well as the mean and variance of its power output in each case. These optimized protocols exhibit significant improvements in power and efficiency compared to the naive approach. Our results also show that, when optimizing for efficiency, boosting the power output of a Szilard engine inevitably comes at the cost of increased power fluctuations.","lang":"eng"}],"_id":"20733","intvolume":"         7","file":[{"creator":"dernst","checksum":"66f2b572a36a7b5fe611a7639a8b6f12","file_id":"20753","date_created":"2025-12-09T14:05:56Z","file_size":536624,"success":1,"content_type":"application/pdf","relation":"main_file","access_level":"open_access","date_updated":"2025-12-09T14:05:56Z","file_name":"2025_PhysReviewResearch_Aggarwal.pdf"}],"oa_version":"Published Version","title":"Rapid optimal work extraction from a quantum-dot information engine","article_processing_charge":"Yes","arxiv":1,"OA_place":"publisher","year":"2025","author":[{"last_name":"Aggarwal","first_name":"Kushagra","full_name":"Aggarwal, Kushagra"},{"full_name":"Rolandi, Alberto","first_name":"Alberto","last_name":"Rolandi"},{"last_name":"Yang","first_name":"Yikai","full_name":"Yang, Yikai"},{"first_name":"Joseph","full_name":"Hickie, Joseph","last_name":"Hickie"},{"last_name":"Jirovec","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","full_name":"Jirovec, Daniel","first_name":"Daniel","orcid":"0000-0002-7197-4801"},{"last_name":"Ballabio","first_name":"Andrea","full_name":"Ballabio, Andrea"},{"last_name":"Chrastina","full_name":"Chrastina, Daniel","first_name":"Daniel"},{"last_name":"Isella","full_name":"Isella, Giovanni","first_name":"Giovanni"},{"first_name":"Mark T.","full_name":"Mitchison, Mark T.","last_name":"Mitchison"},{"full_name":"Perarnau-Llobet, Martí","first_name":"Martí","last_name":"Perarnau-Llobet"},{"first_name":"Natalia","full_name":"Ares, Natalia","last_name":"Ares"}],"date_created":"2025-12-07T23:02:02Z","status":"public","acknowledgement":"We thank Georgios Katsaros for providing the device for this experiment.

For such hybrid devices, subgap states play a prominent role in their operation. In this paper, we study these subgap states via Coulomb and tunneling spectroscopy through a superconducting island defined in a semiconductor nanowire fully coated by a superconductor. We systematically explore regimes ranging from an almost decoupled island to the open configuration. In the weak-coupling regime, the experimental observations are very similar in the absence of a magnetic field and when one flux quantum pierces the superconducting shell. Conversely, in the strong-coupling regime, significant distinctions emerge between the two cases. We attribute this distinct behavior to the existence of subgap states at one flux quantum, which become observable only for sufficiently strong coupling to the leads. We support our interpretation using a simple model to describe transport through the island. Our study highlights the importance of studying a broad range of tunnel couplings for understanding the rich physics of hybrid devices."}],"intvolume":"         7","article_type":"original","month":"04","DOAJ_listed":"1","volume":7,"publication":"Physical Review Research","department":[{"_id":"GeKa"}],"date_updated":"2025-11-06T14:22:43Z","corr_author":"1","oa":1},{"APC_amount":"7068 EUR","date_published":"2025-03-01T00:00:00Z","scopus_import":"1","isi":1,"language":[{"iso":"eng"}],"ddc":["530"],"day":"01","type":"journal_article","article_processing_charge":"Yes","title":"Strong charge-photon coupling in planar germanium enabled by granular aluminium superinductors","oa_version":"Published Version","ec_funded":1,"pmid":1,"arxiv":1,"OA_place":"publisher","author":[{"orcid":"0009-0003-9037-8831","first_name":"Marian","full_name":"Janik, Marian","last_name":"Janik","id":"396A1950-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Roux","id":"53f93ea2-803f-11ed-ab7e-b283135794ef","first_name":"Kevin Etienne Robert","full_name":"Roux, Kevin Etienne Robert"},{"id":"18777c01-896a-11ed-bdf8-e4851dc07d16","last_name":"Borja Espinosa","first_name":"Carla N","full_name":"Borja Espinosa, Carla N"},{"full_name":"Sagi, Oliver","first_name":"Oliver","id":"71616374-A8E9-11E9-A7CA-09ECE5697425","last_name":"Sagi"},{"full_name":"Baghdadi, Abdulhamid","first_name":"Abdulhamid","id":"160D87FA-96B5-11E9-BF77-7626E6697425","last_name":"Baghdadi"},{"id":"38756BB2-F248-11E8-B48F-1D18A9856A87","last_name":"Adletzberger","full_name":"Adletzberger, Thomas","first_name":"Thomas"},{"last_name":"Calcaterra","full_name":"Calcaterra, Stefano","first_name":"Stefano"},{"last_name":"Botifoll","first_name":"Marc","full_name":"Botifoll, Marc"},{"full_name":"Garzón Manjón, Alba","first_name":"Alba","last_name":"Garzón Manjón"},{"last_name":"Arbiol","first_name":"Jordi","full_name":"Arbiol, Jordi"},{"last_name":"Chrastina","first_name":"Daniel","full_name":"Chrastina, Daniel"},{"first_name":"Giovanni","full_name":"Isella, Giovanni","last_name":"Isella"},{"last_name":"Pop","first_name":"Ioan M.","full_name":"Pop, Ioan M."},{"last_name":"Katsaros","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","first_name":"Georgios","full_name":"Katsaros, Georgios","orcid":"0000-0001-8342-202X"}],"year":"2025","project":[{"_id":"34c0acea-11ca-11ed-8bc3-8775e10fd452","name":"Integrated Germanium Quantum Technology","grant_number":"101069515"},{"name":"Towards scalable hut wire quantum devices","grant_number":"P32235","call_identifier":"FWF","_id":"237B3DA4-32DE-11EA-91FC-C7463DDC885E"},{"grant_number":"I05060","name":"High impedance circuit quantum electrodynamics with hole spins","_id":"c0977eea-5a5b-11eb-8a69-a862db0cf4d1"},{"name":"Merging spin and superconducting qubits in planar Ge","grant_number":"P36507","_id":"bd8bd29e-d553-11ed-ba76-f0070d4b237a"},{"call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","name":"IST-BRIDGE: International postdoctoral program"},{"name":"FWF Open Access Fund","_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1","call_identifier":"FWF"}],"acknowledgement":"We acknowledge Franco De Palma, Mahya Khorramshahi, Fabian Oppliger, Thomas Reisinger, Pasquale Scarlino and Xiao Xue for helpful discussions.

Moreover, thanks to their high impedance, quantum buses made of such materials enable large zero-point fluctuations of the voltage, boosting the coupling rates to spin and charge qubits. However, fully exploiting the potential of disordered or granular superconductors is challenging, as their inductance and, therefore, impedance at high values are difficult to control. Here, we report a reproducible fabrication of granular aluminium resonators by developing a wireless ohmmeter, which allows in situ measurements during film deposition and, therefore, control of the kinetic inductance of granular aluminium films. Reproducible fabrication of circuits with impedances (inductances) exceeding 13 kΩ (1 nH per square) is now possible. By integrating a 7.9 kΩ resonator with a germanium double quantum dot, we demonstrate strong charge-photon coupling with a rate of gc/2π = 566 ± 2 MHz. This broadly applicable method opens the path for novel qubits and high-fidelity, long-distance two-qubit gates."}],"_id":"19401","intvolume":"        16","quality_controlled":"1","OA_type":"gold","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"2103","citation":{"ama":"Janik M, Roux KER, Borja Espinosa CN, et al.

Here, we provide a quantitative estimate of the carbon emissions associated with conference attendance by analyzing travel data from participants of 10 international conferences in the field of magnetic resonance, namely EUROMAR, ENC and ICMRBS. We find that attending a EUROMAR conference produces, on average, more than 1 t CO2 eq.. For the analyzed conferences outside Europe, the corresponding value is about 2–3 times higher, on average, with intercontinental trips amounting to up to 5 t. We compare these conference-related emissions to other activities associated with research and show that conference travel is a substantial portion of the total climate footprint of a researcher in magnetic resonance. We explore several strategies to reduce these emissions, including the impact of selecting conference venues more strategically and the possibility of decentralized conferences. Through a detailed comparison of train versus air travel – accounting for both direct and infrastructure-related emissions – we demonstrate that train travel offers considerable carbon savings. These data may provide a basis for strategic choices of future conferences in the field and for individuals deciding on their conference attendance.","lang":"eng"}],"publication":"Magnetic Resonance","department":[{"_id":"JoFi"},{"_id":"GaTk"},{"_id":"JoCs"},{"_id":"EvBe"},{"_id":"TaHa"},{"_id":"GradSch"},{"_id":"GeKa"},{"_id":"PaSc"}],"DOAJ_listed":"1","volume":6,"related_material":{"link":[{"url":"https://ista.ac.at/en/news/carbon-footprint-of-conference-travel/","relation":"research_data","description":"News on ISTA website"}],"record":[{"status":"public","id":"20242","relation":"research_data"}]},"date_updated":"2026-05-20T08:01:13Z","oa":1,"corr_author":"1"},{"volume":16,"DOAJ_listed":"1","department":[{"_id":"GeKa"}],"publication":"Nature Communications","_id":"19424","intvolume":"        16","abstract":[{"text":"Hole spin qubits are rapidly emerging as the workhorse of semiconducting quantum processors because of their large spin-orbit interaction, enabling fast all-electric operations at low power. However, spin-orbit interaction also causes non-uniformities in devices, resulting in locally varying qubit energies and site-dependent anisotropies. While these anisotropies can be used to drive single-spins, if not properly harnessed, they can hinder the path toward large-scale quantum processors. Here, we report on microwave-driven singlet-triplet qubits in planar germanium and use them to investigate the anisotropy of two spins in a double quantum dot. We show two distinct operating regimes depending on the magnetic field direction. For in-plane fields, the two spins are largely anisotropic, and electrically tunable, which enables to measure all the available transitions; coherence times exceeding 3 $\\mu$s are extracted. For out-of-plane fields, they have an isotropic response but preserve the substantial energy difference required to address the singlet-triplet qubit. Even in this field direction, where the qubit lifetime\r\nis strongly affected by nuclear spins, we find 400 ns coherence times. Our work adds a valuable tool to investigate and harness the anisotropy of spin qubits and can be implemented in any large-scale NxN device, facilitating the path towards scalable quantum processors.","lang":"eng"}],"file":[{"creator":"dernst","checksum":"13fe84cddc9d4e47213bf17acdac70d7","file_id":"19645","file_size":1548756,"date_created":"2025-05-05T07:08:23Z","success":1,"content_type":"application/pdf","relation":"main_file","date_updated":"2025-05-05T07:08:23Z","access_level":"open_access","file_name":"2025_NatureComm_SaezMollejo.pdf"}],"month":"04","article_type":"original","oa":1,"corr_author":"1","external_id":{"isi":["001475587400022"],"pmid":["40274808"],"arxiv":["2408.03224"]},"date_updated":"2026-05-20T22:31:25Z","related_material":{"link":[{"description":"News on ISTA website","url":"https://ista.ac.at/en/news/the-shadow-of-an-electron/","relation":"research_data"}],"record":[{"relation":"research_data","id":"19409","status":"public"},{"relation":"dissertation_contains","id":"19836","status":"public"}]},"publication_identifier":{"eissn":["2041-1723"]},"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"doi":"10.1038/s41467-025-58969-y","has_accepted_license":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"OA_type":"gold","quality_controlled":"1","file_date_updated":"2025-05-05T07:08:23Z","citation":{"chicago":"Saez Mollejo, Jaime, Daniel Jirovec, Yona A Schell, Josip Kukucka, Stefano Calcaterra, Daniel Chrastina, Giovanni Isella, Maximilian Rimbach-Russ, Stefano Bosco, and Georgios Katsaros. “Exchange Anisotropies in Microwave-Driven Singlet-Triplet Qubits.” <i>Nature Communications</i>.

Today, we stand at the dawn of the quantum technology era. While some quantum\r\ntechnologies follow well-defined roadmaps, others are still in the exciting and uncertain early\r\nstages of development. In the fields of quantum computing and quantum simulation, research\r\nis being conducted across a wide variety of platforms. Each of these demonstrates control over\r\nquantum properties but also faces challenges in scaling up to the level of a mature technology.\r\nThis thesis explores some of the fundamental properties of hole spin qubits in planar germanium.\r\nSemiconductor spin qubits are considered strong candidates for the realization of quantum\r\nprocessors, owing to their long relaxation and coherence times, as well as their compatibility\r\nwith existing semiconductor industry infrastructure. Among these, hole spin qubits in planar\r\ngermanium are particularly promising. Their advantages include a large effective mass, which\r\neases fabrication constraints; inherent protection from hyperfine noise; and strong spin-orbit\r\ninteraction, which enables fast and purely electrical control. However, spin-orbit coupling also\r\nintroduces site-dependent variability across qubits, particularly in the g-tensors and spin-flip\r\ntunneling, which might cause that the quantization axes are not aligned. In this thesis, we\r\ninvestigate the tilt between the quantization axes of two hole spins hosted in a double quantum\r\ndot as a function of both the magnetic field direction and various electrostatic configurations,\r\ndemonstrating that both parameters influence this tilt. We conclude by introducing a machine-learning-assisted routine to automatically tune baseband spin qubits. This approach may prove\r\nto be a powerful tool for characterizing spin-orbit effects and gaining deeper insight into the\r\nphysics governing spin qubit behavior.\r\n","lang":"eng"}],"_id":"19836","department":[{"_id":"GradSch"},{"_id":"GeKa"}],"supervisor":[{"orcid":"0000-0001-8342-202X","first_name":"Georgios","full_name":"Katsaros, Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","last_name":"Katsaros"}]},{"date_created":"2024-12-01T23:01:53Z","status":"public","acknowledgement":"The authors thank Simone Frasca, Vincent Jouanny, Guillaume Beaulieu, Camille Roy, Dominic Dahinden, Davide Lombardo, Daniel Chrastina, and Siddhart Gautam for contributing to some cleanroom fabrication steps, the measurement setup, device simulations, data analysis, and for the useful discussions.

Here, we present strong coupling between a hole charge qubit, defined in a double quantum dot (DQD) in planar Ge, and microwave photons in a high-impedance (Zr = 1.3 kΩ) resonator based on an array of superconducting quantum interference devices (SQUIDs). Our investigation reveals vacuum-Rabi splittings with coupling strengths up to g0/2π = 260 MHz, and a cooperativity of C ~ 100, dependent on DQD tuning. Furthermore, utilizing the frequency tunability of our resonator, we explore the quenched energy splitting associated with strong Coulomb correlation effects in Ge QDs. The observed enhanced coherence of the strongly correlated excited state signals the presence of distinct symmetries within related spin functions, serving as a precursor to the strong coupling between photons and spin-charge hybrid qubits in planar Ge. This work paves the way towards coherent quantum connections between remote hole qubits in planar Ge, required to scale up hole-based quantum processors.","lang":"eng"}],"file":[{"content_type":"application/pdf","file_size":5288092,"success":1,"date_created":"2024-12-03T11:00:15Z","file_id":"18611","checksum":"ef9f99a84089c388904cc8aa8d89c55a","creator":"dernst","file_name":"2024_NatureComm_dePalma.pdf","access_level":"open_access","date_updated":"2024-12-03T11:00:15Z","relation":"main_file"}],"article_type":"original","month":"12","oa":1,"external_id":{"isi":["001362684200001"],"pmid":["39580488"]},"date_updated":"2025-09-08T14:46:06Z"},{"scopus_import":"1","language":[{"iso":"eng"}],"isi":1,"type":"journal_article","day":"01","ddc":["530"],"issue":"6","date_published":"2024-12-01T00:00:00Z","project":[{"_id":"c0977eea-5a5b-11eb-8a69-a862db0cf4d1","name":"High impedance circuit quantum electrodynamics with hole spins","grant_number":"I05060"},{"name":"Integrated Germanium Quantum Technology","grant_number":"101069515","_id":"34c0acea-11ca-11ed-8bc3-8775e10fd452"}],"status":"public","date_created":"2024-12-15T23:01:50Z","acknowledgement":"We thank Nicholas Sim for providing help with the experiment and Sebastian Orbell for helpful discussions.

We present an approach for compensating for this crosstalk effect allowing for the gate voltages of the measured device to be swept in a 1-V × 1-V window while maintaining a sensor configuration chosen by a Bayesian optimizer.

Here, we theoretically explore how an alternating current bias can tune the response of such a diode. We show that for slow driving there is always a regime where the system can only carry zero-voltage dc current in one direction, thus effectively behaving as an ideal Josephson diode. Under fast driving, the diode efficiency is also tunable, although the ideal regime cannot be reached in this case. We also investigate the residual dissipation due to the time-dependent current bias and show that it remains small. All our conclusions are solely based on the critical current asymmetry of the junction, and are thus compatible with any Josephson diode.","lang":"eng"}],"intvolume":"         6"},{"isi":1,"language":[{"iso":"eng"}],"scopus_import":"1","day":"27","ddc":["530"],"type":"journal_article","date_published":"2024-07-27T00:00:00Z","acknowledgement":"We acknowledge Ang Li, Erik P.

Each device needs to be tuned to operation conditions and each device realisation requires a different tuning protocol. We demonstrate that it is possible to automate the tuning of a 4-gate Si FinFET, a 5-gate GeSi nanowire and a 7-gate Ge/SiGe heterostructure double quantum dot device from scratch with the same algorithm. We achieve tuning times of 30, 10, and 92 min, respectively. The algorithm also provides insight into the parameter space landscape for each of these devices, allowing for the characterization of the regions where double quantum dot regimes are found.

Superconducting electronics aims to complement semiconductor technology, while hybrid architectures are at the forefront of new ideas such as topological superconductivity and protected qubits. In this work, we engineer the induced superconductivity in two-dimensional germanium hole gas by varying the distance between the quantum well and the aluminum. We demonstrate a hard superconducting gap and realize an electrically and flux tunable superconducting diode using a superconducting quantum interference device (SQUID). This allows to tune the current phase relation (CPR), to a regime where single Cooper pair tunneling is suppressed, creating a sin(2y) CPR. Shapiro experiments complement this interpretation and the microwave drive allows to create a diode with ≈ 100% efficiency.
