Impedance-engineering is implemented using a lumped-element series LC circuit. We use a simpler lithography process where the entire device—impedance transformer and Josephson parametric amplifier (JPA)—is patterned in a single electron beam lithography step, followed by a double-angle Dolan-bridge technique for Al–AlOx–Al deposition. We observe amplification with 18 dB gain over a wide 400 MHz bandwidth centered around 5.3 GHz with added noise approaching the quantum limit, and a saturation power of −114 dBm. To accurately explain our experimental results, we extend existing theories for IEJPAs to incorporate the full sine nonlinearity of both the JPA and the transformer. Our work provides a route to simpler realization of broadband JPAs and a theoretical foundation for a regime of JPA operation that has been less explored in literature.","lang":"eng"}],"type":"journal_article","oa":1,"title":"Impedance-engineered Josephson parametric amplifier with single-step lithography","month":"12","scopus_import":"1","day":"22","doi":"10.1063/5.0290636","year":"2025","author":[{"first_name":"Lipi","last_name":"Patel","full_name":"Patel, Lipi"},{"orcid":"0000-0002-1965-4309","last_name":"Hawaldar","first_name":"Samarth","full_name":"Hawaldar, Samarth","id":"221708e1-1ff6-11ee-9fa6-85146607433e"},{"first_name":"Aditya","last_name":"Panikkar","full_name":"Panikkar, Aditya"},{"full_name":"Shankar, Athreya","last_name":"Shankar","first_name":"Athreya"},{"full_name":"Suri, Baladitya","first_name":"Baladitya","last_name":"Suri"}],"article_type":"original","article_number":"254001"},{"date_published":"2023-08-28T00:00:00Z","volume":123,"oa_version":"Published Version","publisher":"AIP Publishing","publication_status":"published","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"isi":1,"acknowledgement":"The work was supported by IST Austria.

Our approach is based on using a near-infrared probe beam which interacts with a mid-IR beam via wavelength-non-degenerate cross-phase modulation (XPM). By carefully measuring XPM-induced spectral modifications in the probe beam and comparing the experimental data with simulation results, we extract the value for the non-degenerate Kerr index. Finally, in order to obtain the value of degenerate mid-IR Kerr index, we use the well-established two-band formalism of Sheik-Bahae et al., which is shown to become particularly simple in the limit of low frequencies. The proposed technique is complementary to the conventional techniques, such as z-scan, and has the advantage of not requiring any mid-infrared detectors."}],"title":"Mid-infrared Kerr index evaluation via cross-phase modulation with a near-infrared probe beam","month":"08","ddc":["530"],"article_type":"original","article_number":"091104","scopus_import":"1","day":"28","doi":"10.1063/5.0161713","year":"2023","author":[{"id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","full_name":"Lorenc, Dusan","last_name":"Lorenc","first_name":"Dusan"},{"full_name":"Alpichshev, Zhanybek","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","last_name":"Alpichshev","first_name":"Zhanybek","orcid":"0000-0002-7183-5203"}]},{"day":"12","scopus_import":"1","author":[{"first_name":"Anthony J.","last_name":"Sigillito","full_name":"Sigillito, Anthony J."},{"last_name":"Covey","first_name":"Jacob P.","full_name":"Covey, Jacob P."},{"first_name":"Johannes M","last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Karl","last_name":"Petersson","full_name":"Petersson, Karl"},{"full_name":"Preble, Stefan","first_name":"Stefan","last_name":"Preble"}],"year":"2022","doi":"10.1063/5.0097339","article_type":"letter_note","article_number":"190401","title":"Emerging qubit systems: Guest editorial","month":"05","date_created":"2022-05-29T22:01:53Z","abstract":[{"lang":"eng","text":"Over the past few years, the field of quantum information science has seen tremendous progress toward realizing large-scale quantum computers. With demonstrations of quantum computers outperforming classical computers for a select range of problems,1–3 we have finally entered the noisy, intermediate-scale quantum (NISQ) computing era. While the quantum computers of today are technological marvels, they are not yet error corrected, and it is unclear whether any system will scale beyond a few hundred logical qubits without significant changes to architecture and control schemes. Today's quantum systems are analogous to the ENIAC (Electronic Numerical Integrator And Computer) and EDVAC (Electronic Discrete Variable Automatic Computer) systems of the 1940s, which ran on vacuum tubes. These machines were built on a solid, nominally scalable architecture and when they were developed, nobody could have predicted the development of the transistor and the impact of the resulting semiconductor industry. Simply put, the computers of today are nothing like the early computers of the 1940s. We believe that the qubits of future fault-tolerant quantum systems will look quite different from the qubits of the NISQ machines in operation today. This Special Topic issue is devoted to new and emerging quantum systems with a focus on enabling technologies that can eventually lead to the quantum analog to the transistor. We have solicited both research4–18 and perspective articles19–21 to discuss new and emerging qubit systems with a focus on novel materials, encodings, and architectures. We are proud to present a collection that touches on a wide range of technologies including superconductors,7–13,21 semiconductors,15–17,19 and individual atomic qubits.18\r\n"}],"main_file_link":[{"url":"https://doi.org/10.1063/5.0097339","open_access":"1"}],"type":"journal_article","oa":1,"status":"public","quality_controlled":"1","citation":{"apa":"Sigillito, A.

This perspective piece asks the question: can entanglement usefully improve cold-atom sensors, in the sense that it gives new sensing capabilities unachievable with current state-of-the-art devices? We briefly review the state-of-the-art in precision cold-atom sensing, focusing on clocks and inertial sensors, identifying the potential benefits entanglement could bring to these devices, and the challenges that need to be overcome to realize these benefits. We survey demonstrated methods of generating metrologically useful entanglement in cold-atom systems, note their relative strengths and weaknesses, and assess their prospects for near-to-medium term quantum-enhanced cold-atom sensing."}],"date_created":"2021-04-18T22:01:40Z","oa":1,"type":"journal_article","month":"04","title":"Improving cold-atom sensors with quantum entanglement: Prospects and challenges","year":"2021","doi":"10.1063/5.0050235","author":[{"full_name":"Szigeti, Stuart S.","last_name":"Szigeti","first_name":"Stuart S."},{"id":"4C02D85E-F248-11E8-B48F-1D18A9856A87","full_name":"Hosten, Onur","first_name":"Onur","last_name":"Hosten","orcid":"0000-0002-2031-204X"},{"full_name":"Haine, Simon A.","first_name":"Simon A.","last_name":"Haine"}],"scopus_import":"1","day":"07","article_number":"140501","article_type":"original"},{"article_type":"original","article_number":"041104","scopus_import":"1","day":"27","doi":"10.1063/5.0035419","year":"2021","author":[{"first_name":"Zin","last_name":"Lin","full_name":"Lin, Zin"},{"first_name":"Charles","last_name":"Roques-Carmes","full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82"},{"full_name":"Christiansen, Rasmus E.","last_name":"Christiansen","first_name":"Rasmus E."},{"full_name":"Soljačić, Marin","last_name":"Soljačić","first_name":"Marin"},{"full_name":"Johnson, Steven G.","last_name":"Johnson","first_name":"Steven G."}],"title":"Computational inverse design for ultra-compact single-piece metalenses free of chromatic and angular aberration","month":"01","ddc":["530"],"type":"journal_article","oa":1,"date_created":"2026-03-30T12:22:47Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1063/5.0035419"}],"abstract":[{"text":"We present full-Maxwell topology-optimization design of a single-piece multilayer metalens, about 10 wavelengths λ in thickness, which simultaneously focuses over a 60° angular range and a 23% spectral bandwidth without suffering chromatic or angular aberration, a “plan-achromat.” At all angles and frequencies, it achieves diffraction-limited focusing (Strehl ratio &amp;gt;0.8) and an absolute focusing efficiency of &amp;gt;50%.

Core@shell NCs, in which one or more inorganic layers overcoat individual NCs, recently received significant attention due to their remarkable optical characteristics. Reduced Auger recombination, suppressed blinking, and enhanced carrier multiplication are among the merits of core@shell NCs. Despite their importance in device development, the influence of the shell and the surface modification of the core@shell NC assemblies on the charge carrier transport remains a pertinent research objective. Type-II PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated, still exhibit instability of their electron \r\n ransport. Here, we demonstrate the enhancement of electron transport and stability in PbTe@PbS core@shell NC assemblies using iodide as a surface passivating ligand. The combination of the PbS shelling and the use of the iodide ligand contributes to the addition of one mobile electron for each core@shell NC. Furthermore, both electron mobility and on/off current modulation ratio values of the core@shell NC field-effect transistor are steady with the usage of iodide. Excellent stability in these exclusively electron-transporting core@shell NCs paves the way for their utilization in electronic devices.

Key to the qubit fabrication is the use of an anhydrous hydrofluoric vapor process which selectively removes the lossy silicon oxide buried underneath the silicon device layer. For a 5.6 GHz qubit measured dispersively by a 7.1 GHz resonator, we find T1 = 3.5 μs and T∗2 = 2.2 μs. This process in principle permits the co-fabrication of silicon photonic and mechanical elements, providing a route towards chip-scale integration of electro-opto-mechanical transducers for quantum networking of superconducting microwave quantum circuits. The additional processing steps are compatible with established fabrication techniques for aluminum transmon qubits on silicon.","lang":"eng"}],"date_created":"2018-12-11T11:48:33Z","oa":1,"type":"journal_article","quality_controlled":"1","arxiv":1,"status":"public"}]
