However, this approach increases both the footprint and the parasitic cross-coupling and is ultimately limited by radiation losses—a potential roadblock for scaling up quantum processors to millions of qubits. In this work we present transmon qubits with sizes as low as 36 × 39 µm2 with  100-nm-wide vacuum-gap capacitors that are micromachined from commercial silicon-on-insulator wafers and shadow evaporated with aluminum. We achieve a vacuum participation ratio up to 99.6% in an in-plane design that is compatible with standard coplanar circuits. Qubit relaxationtime measurements for small gaps with high zero-point electric field variance of up to 22 V/m reveal a double exponential decay indicating comparably strong qubit interaction with long-lived two-level systems. The exceptionally high selectivity of up to 20 dB to the superconductor-vacuum interface allows us to precisely back out the sub-single-photon dielectric loss tangent of aluminum oxide previously exposed to ambient conditions. In terms of future scaling potential, we achieve a ratio of qubit quality factor to a footprint area equal to 20 µm−2, which is comparable with the highest T1 devices relying on larger geometries, a value that could improve substantially for lower surface-loss superconductors.

The device is based on a single crystal whispering gallery mode resonator integrated into a 3D-microwave cavity. The specific design relies on a new combination of thin-film technology and conventional machining that is optimized for the lowest dissipation rates in the microwave, optical, and mechanical domains. We extract important device properties from finite-element simulations and predict continuous variable entanglement generation rates on the order of a Mebit/s for optical pump powers of only a few tens of microwatts. We compare the quantum state transfer fidelities of coherent, squeezed, and non-Gaussian cat states for both teleportation and direct conversion protocols under realistic conditions. Combining the unique capabilities of circuit quantum electrodynamics with the resilience of fiber optic communication could facilitate long-distance solid-state qubit networks, new methods for quantum signal synthesis, quantum key distribution, and quantum enhanced detection, as well as more power-efficient classical sensing and modulation."}],"corr_author":"1","day":"01","oa":1,"title":"Electro-optic entanglement source for microwave to telecom quantum state transfer","volume":5,"year":"2019","status":"public","month":"12","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"date_created":"2019-12-09T08:18:56Z","department":[{"_id":"JoFi"}],"publisher":"Springer Nature","citation":{"ista":"Rueda Sanchez AR, Hease WJ, Barzanjeh S, Fink JM. 2019.

Continuous-variable entangled fields—known as Einstein–Podolsky–Rosen (EPR) states—are spatially separated two-mode squeezed states that can be used for quantum teleportation and quantum communication2. In the optical domain, EPR states are typically generated using nondegenerate optical amplifiers3, and at microwave frequencies Josephson circuits can serve as a nonlinear medium4,5,6. An outstanding goal is to deterministically generate and distribute entangled states with a mechanical oscillator, which requires a carefully arranged balance between excitation, cooling and dissipation in an ultralow noise environment. Here we observe stationary emission of path-entangled microwave radiation from a parametrically driven 30-micrometre-long silicon nanostring oscillator, squeezing the joint field operators of two thermal modes by 3.40 decibels below the vacuum level. The motion of this micromechanical system correlates up to 50 photons per second per hertz, giving rise to a quantum discord that is robust with respect to microwave noise7. Such generalized quantum correlations of separable states are important for quantum-enhanced detection8 and provide direct evidence of the non-classical nature of the mechanical oscillator without directly measuring its state9. This noninvasive measurement scheme allows to infer information about otherwise inaccessible objects, with potential implications for sensing, open-system dynamics and fundamental tests of quantum gravity. In the future, similar on-chip devices could be used to entangle subsystems on very different energy scales, such as microwave and optical photons.","lang":"eng"}],"acknowledged_ssus":[{"_id":"NanoFab"}],"language":[{"iso":"eng"}],"year":"2019","volume":570,"title":"Stationary entangled radiation from micromechanical motion","oa":1,"day":"27"},{"oa_version":"Submitted Version","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","pmid":1,"author":[{"last_name":"Salari","first_name":"Vahid","full_name":"Salari, Vahid"},{"full_name":"Barzanjeh, Shabir","orcid":"0000-0003-0415-1423","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","last_name":"Barzanjeh","first_name":"Shabir"},{"first_name":"Michal","last_name":"Cifra","full_name":"Cifra, Michal"},{"full_name":"Simon, Christoph","last_name":"Simon","first_name":"Christoph"},{"first_name":"Felix","last_name":"Scholkmann","full_name":"Scholkmann, Felix"},{"first_name":"Zahra","last_name":"Alirezaei","full_name":"Alirezaei, Zahra"},{"full_name":"Tuszynski, Jack","first_name":"Jack","last_name":"Tuszynski"}],"external_id":{"isi":["000439042800001"],"pmid":["29293441"]},"isi":1,"acknowledgement":"The work of SB has been supported by the European Unions Horizon 2020 research and innovation program under the Marie Sklodowska Curie grant agreement No MSC-IF 707438 SUPEREOM.

Proposals have been put forward for the realization of artificial magnetic fields for photons and phonons; experimental progress is fast making these proposals a reality. Much work has concentrated on the use of such systems for controlling the flow of signals, e.g., to create isolators or directional amplifiers for optical signals. In this Letter, we build on this work but move in a different direction. We develop the theory of and discuss a potential realization for the controllable flow of thermal noise in quantum systems. We demonstrate theoretically that the unidirectional flow of thermal noise is possible within quantum cascaded systems. Viewing an optomechanical platform as a cascaded system we show here that one can ultimately control the direction of the flow of thermal noise. By appropriately engineering the mechanical resonator, which acts as an artificial reservoir, the flow of thermal noise can be constrained to a desired direction, yielding a thermal rectifier. The proposed quantum thermal noise rectifier could potentially be used to develop devices such as a thermal modulator, a thermal router, and a thermal amplifier for nanoelectronic devices and superconducting circuits.","lang":"eng"}],"publist_id":"7387","language":[{"iso":"eng"}],"article_number":"060601 ","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1706.09051"}],"ec_funded":1,"publication_status":"published","doi":"10.1103/PhysRevLett.120.060601","publication":"Physical Review Letters","type":"journal_article","date_updated":"2024-10-22T09:36:24Z","scopus_import":"1","article_processing_charge":"No"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","isi":1,"external_id":{"isi":["000412999700021"]},"author":[{"first_name":"Shabir","last_name":"Barzanjeh","full_name":"Barzanjeh, Shabir","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0415-1423"},{"orcid":"0000-0001-6613-1378","id":"45598606-F248-11E8-B48F-1D18A9856A87","full_name":"Wulf, Matthias","last_name":"Wulf","first_name":"Matthias"},{"last_name":"Peruzzo","first_name":"Matilda","orcid":"0000-0002-3415-4628","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","full_name":"Peruzzo, Matilda"},{"full_name":"Kalaee, Mahmoud","first_name":"Mahmoud","last_name":"Kalaee"},{"full_name":"Dieterle, Paul","first_name":"Paul","last_name":"Dieterle"},{"full_name":"Painter, Oskar","first_name":"Oskar","last_name":"Painter"},{"full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M","last_name":"Fink"}],"file":[{"file_name":"IST-2017-867-v1+1_s41467-017-01304-x.pdf","file_size":1467696,"checksum":"b68dafa71d1834c23b742cd9987a3d5f","date_created":"2018-12-12T10:15:25Z","access_level":"open_access","relation":"main_file","creator":"system","content_type":"application/pdf","file_id":"5145","date_updated":"2020-07-14T12:48:06Z"}],"has_accepted_license":"1","month":"10","status":"public","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"date_created":"2018-12-11T11:48:33Z","department":[{"_id":"JoFi"}],"citation":{"ieee":"S.

Here we demonstrate an on-chip magnetic-free circulator based on reservoir-engineered electromechanic interactions. Directional circulation is achieved with controlled phase-sensitive interference of six distinct electro-mechanical signal conversion paths. The presented circulator is compact, its silicon-on-insulator platform is compatible with both superconducting qubits and silicon photonics, and its noise performance is close to the quantum limit. With a high dynamic range, a tunable bandwidth of up to 30 MHz and an in situ reconfigurability as beam splitter or wavelength converter, it could pave the way for superconducting qubit processors with multiplexed on-chip signal processing and readout."}],"corr_author":"1","oa":1,"day":"16","year":"2017","title":"Mechanical on chip microwave circulator","volume":8,"article_processing_charge":"Yes (in subscription journal)","scopus_import":"1","ddc":["539"],"type":"journal_article","publication":"Nature Communications","date_updated":"2025-07-10T11:54:54Z","pubrep_id":"867"},{"oa_version":"Submitted Version","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","author":[{"last_name":"Barzanjeh","first_name":"Shabir","full_name":"Barzanjeh, Shabir","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0415-1423"},{"first_name":"Vahid","last_name":"Salari","full_name":"Salari, Vahid"},{"first_name":"Jack","last_name":"Tuszynski","full_name":"Tuszynski, Jack"},{"full_name":"Cifra, Michal","last_name":"Cifra","first_name":"Michal"},{"first_name":"Christoph","last_name":"Simon","full_name":"Simon, Christoph"}],"arxiv":1,"external_id":{"arxiv":["1612.07061"],"isi":["000405367200012"]},"isi":1,"status":"public","month":"07","publisher":"American Institute of Physics","citation":{"ama":"Barzanjeh S, Salari V, Tuszynski J, Cifra M, Simon C.

However, little is known about the dynamic (high-frequency) mechanical properties of microtubules. Here, we theoretically propose to control the vibrations of a doubly clamped microtubule by tip electrodes and to detect its motion via the optomechanical coupling between the vibrational modes of the microtubule and an optical cavity. In the presence of a red-detuned strong pump laser, this coupling leads to optomechanical-induced transparency of an optical probe field, which can be detected with state-of-the art technology. The center frequency and line width of the transparency peak give the resonance frequency and damping rate of the microtubule, respectively, while the height of the peak reveals information about the microtubule-cavity field coupling. Our method opens the new possibilities to gain information about the physical properties of microtubules, which will enhance our capability to design physical cancer treatment protocols as alternatives to chemotherapeutic drugs.","lang":"eng"}],"article_number":"012404","language":[{"iso":"eng"}],"publist_id":"6997","title":"Optomechanical proposal for monitoring microtubule mechanical vibrations","volume":96,"year":"2017","day":"12","oa":1,"article_processing_charge":"No","scopus_import":"1","date_updated":"2025-09-10T11:08:33Z","publication":" Physical Review E Statistical Nonlinear and Soft Matter Physics ","type":"journal_article"}]
