The proposed radiometer is based on an electro-optic upconverter that boosts up microwave photons energy by upconverting them into an optical domain what makes them immune to thermal noise even if operating at room temperature. The converter uses a high-quality factor whispering gallery\r\nmode (WGM) resonator providing naturally narrow bandwidth and therefore might be useful for applications like microwave hyperspectral sensing. The upconversion process is explained by\r\nproviding essential information about photon conversion efficiency and sensitivity. To prove the concept, we describe an experiment which shows state-of-the-art photon conversion efficiency n=10-5 per mW of pump power at the frequency of 80 GHz.","lang":"eng"}],"fulldoi":"https://doi.org/10.23919/eucap48036.2020.9135962","oa_version":"None","citation":{"apa":"Wasiak, M., Botello, G.

Its advantage is particularly evident at low signal powers, a promising feature for applications such as noninvasive biomedical scanning or low-power short-range radar. Here, we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path. Starting from experimental data, we also simulate the case of perfect idler photon number detection, which results in a quantum advantage compared with the relative classical benchmark.

We show efficient frequency conversion between two propagating microwave modes mediated by the radiation pressure interaction with a metalized dielectric nanobeam oscillator. We achieve bidirectional coherent conversion with a total device efficiency of up to ~60%, a dynamic range of 2 × 10^9 photons/s and an instantaneous bandwidth of up to 1.7 kHz. A high fidelity quantum state transfer would be possible if the drive dependent output noise of currently ~14 photons s^−1 Hz^−1 is further reduced.

Surprisingly, the Zeeman paramagnetic effects dominate over orbital coupling on both sides of the transition. In superconducting state it is evidenced by a high upper critical magnetic field 𝐵𝑐2, by its square root dependence on temperature, as well as by the Zeeman splitting of the quasiparticle density of states (DOS) measured by scanning tunneling microscopy. At 𝐵𝑐2 a logarithmic anomaly in DOS is observed. This anomaly is further enhanced in increasing magnetic field, which is explained by the Zeeman splitting of the Altshuler-Aronov DOS driving\r\nthe system into a more insulating or resistive state. Spin dependent Altshuler-Aronov correction is also needed to explain the transport behavior above 𝐵𝑐2.","lang":"eng"}],"oa_version":"Preprint","doi":"10.1103/PhysRevB.102.180508","day":"01","volume":102,"publication":"Physical Review B","issue":"18","quality_controlled":"1","month":"11","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","language":[{"iso":"eng"}],"department":[{"_id":"JoFi"}],"date_updated":"2025-07-10T12:01:27Z","author":[{"last_name":"Zemlicka","id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87","full_name":"Zemlicka, Martin","first_name":"Martin"},{"last_name":"Kopčík","first_name":"M.","full_name":"Kopčík, M."},{"last_name":"Szabó","full_name":"Szabó, P.","first_name":"P."},{"full_name":"Samuely, T.","first_name":"T.","last_name":"Samuely"},{"full_name":"Kačmarčík, J.","first_name":"J.","last_name":"Kačmarčík"},{"last_name":"Neilinger","full_name":"Neilinger, P.","first_name":"P."},{"full_name":"Grajcar, M.","first_name":"M.","last_name":"Grajcar"},{"last_name":"Samuely","first_name":"P.","full_name":"Samuely, P."}],"oa":1,"arxiv":1,"external_id":{"isi":["000591509900003"],"arxiv":["2011.04329"]},"fulldoi":"https://doi.org/10.1103/PhysRevB.102.180508","citation":{"ista":"Zemlicka M, Kopčík M, Szabó P, Samuely T, Kačmarčík J, Neilinger P, Grajcar M, Samuely P. 2020.

The advantage over classical strategies is evident at low signal brightness, a feature which could make the protocol an ideal prototype for non-invasive scanning or low-power short-range radar. Here we experimentally investigate the concept of quantum illumination at microwave frequencies, by generating entangled fields using a Josephson parametric converter which are then amplified to illuminate a room-temperature object at a distance of 1 meter. Starting from experimental data, we simulate the case of perfect idler photon number detection, which results in a quantum advantage compared to the relative classical benchmark. Our results highlight the opportunities and challenges on the way towards a first room-temperature application of microwave quantum circuits.","lang":"eng"}],"oa_version":"Preprint","doi":"10.1109/RadarConf2043947.2020.9266397","day":"21","volume":2020,"publication":"IEEE National Radar Conference - Proceedings","issue":"9","title":"Microwave quantum illumination with a digital phase-conjugated receiver","scopus_import":"1","status":"public","type":"conference","related_material":{"record":[{"id":"7910","status":"public","relation":"earlier_version"}]},"conference":{"start_date":"2020-09-21","end_date":"2020-09-25","location":"Florence, Italy","name":"RadarConf: National Conference on Radar"},"date_published":"2020-09-21T00:00:00Z","acknowledgement":"This work was supported by the Institute of Science and Technology Austria (IST Austria), the European Research Council under grant agreement number 758053 (ERC StG QUNNECT) and the EU’s Horizon 2020 research and innovation programme under grant agreement number 862644 (FET Open QUARTET).

Optical photons, unlike microwave photons, can be transmitted by fiber, making them suitable for long distance quantum communication. Moreover, the optical domain offers access to a large set of very well‐developed quantum optical tools, such as highly efficient single‐photon detectors and long‐lived quantum memories. For a high fidelity microwave to optical transducer, efficient conversion at single photon level and low added noise is needed. Currently, the most promising approaches to build such systems are based on second‐order nonlinear phenomena such as optomechanical and electro‐optic interactions. Alternative approaches, although not yet as efficient, include magneto‐optical coupling and schemes based on isolated quantum systems like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations for the most important microwave‐to‐optical conversion experiments are provided, their implementations are described, and the current limitations and future prospects are discussed."}],"oa_version":"Published Version","doi":"10.1002/qute.201900077","day":"01","file_date_updated":"2021-03-02T12:30:03Z","volume":3,"publication":"Advanced Quantum Technologies","issue":"1","title":"Coherent conversion between microwave and optical photons - An overview of physical implementations","scopus_import":"1","status":"public","related_material":{"link":[{"description":"Cover Page","relation":"poster","url":"https://doi.org/10.1002/qute.202070011"}]},"type":"journal_article","acknowledgement":"The authors thank Amita Deb for useful comments on this manuscript.

Applications include the realization of hardware protected qubits for fault tolerant quantum computing, improved coupling to small dipole moment objects and defining a new quantum metrology standard for the ampere. In this work we refute the widespread notion that superinductors can only be implemented based on kinetic inductance, i.e. using disordered superconductors or Josephson junction arrays. We present modeling, fabrication and characterization of 104 planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled tunneling events and offer high reproducibility, linearity and the ability to couple magnetically - properties that significantly broaden the scope of future quantum circuits.

In contrast to nonlinear optics, electro-optic devices so far require classical modulation fields whose variance is dominated by electronic or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional single-sideband conversion of X band microwave to C band telecom light with a microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of less than or equal to 0.074 photons. This is facilitated by radiative cooling and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures. The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output noise photons per second for the highest available pump power of 1.48 mW puts near-unity efficiency pulsed quantum transduction within reach. Together with the non-Gaussian resources of superconducting qubits this might provide the practical foundation to extend the range and scope of current quantum networks in analogy to electrical repeaters in classical fiber optic communication."}],"publication":"PRX Quantum","file_date_updated":"2021-02-12T11:16:16Z","volume":1,"issue":"2","day":"23","doi":"10.1103/prxquantum.1.020315","ddc":["530"],"author":[{"last_name":"Hease","id":"29705398-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9868-2166","first_name":"William J","full_name":"Hease, William J"},{"orcid":"0000-0001-6249-5860","full_name":"Rueda Sanchez, Alfredo R","first_name":"Alfredo R","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87","last_name":"Rueda Sanchez"},{"full_name":"Sahu, Rishabh","first_name":"Rishabh","orcid":"0000-0001-6264-2162","id":"47D26E34-F248-11E8-B48F-1D18A9856A87","last_name":"Sahu"},{"id":"45598606-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6613-1378","first_name":"Matthias","full_name":"Wulf, Matthias","last_name":"Wulf"},{"last_name":"Arnold","orcid":"0000-0003-1397-7876","first_name":"Georg M","full_name":"Arnold, Georg M","id":"3770C838-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Schwefel","full_name":"Schwefel, Harald G.L.","first_name":"Harald G.L."},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink"}],"oa":1,"ec_funded":1,"date_updated":"2026-11-08T23:30:30Z","language":[{"iso":"eng"}],"department":[{"_id":"JoFi"}],"tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publisher":"American Physical Society","acknowledged_ssus":[{"_id":"M-Shop"}],"date_created":"2021-02-12T10:41:28Z","fulldoi":"https://doi.org/10.1103/prxquantum.1.020315","citation":{"ieee":"W.

A key challenge in this field is obtaining strong coupling between motion and electromagnetic fields without adding additional decoherence. Here we present an electromechanical transducer that integrates a high-frequency (0.42 GHz) hypersonic phononic crystal with a superconducting microwave circuit. The use of a phononic bandgap crystal enables quantum-level transduction of hypersonic mechanical motion and concurrently eliminates decoherence caused by acoustic radiation.

There, complicated electric and magnetic fields varying over subwavelength scales are generally present, which results in photonic phenomena such as extraordinary optical momentum, superchiral fields, and a complex spatial evolution of optical singularities. An understanding of such phenomena requires nanoscale measurements of the complete optical field vector. Although the sensitivity of near- field scanning optical microscopy to the complete electromagnetic field was recently demonstrated, a separation of different components required a priori knowledge of the sample. Here, we introduce a robust algorithm that can disentangle all six electric and magnetic field components from a single near-field measurement without any numerical modeling of the structure. As examples, we unravel the fields of two prototypical nanophotonic structures: a photonic crystal waveguide and a plasmonic nanowire. These results pave the way for new studies of complex photonic phenomena at the nanoscale and for the design of structures that optimize their optical behavior.","lang":"eng"}],"scopus_import":"1","title":"A full vectorial mapping of nanophotonic light fields","file":[{"relation":"main_file","date_created":"2019-03-18T08:08:22Z","content_type":"application/pdf","creator":"dernst","access_level":"open_access","file_size":1119947,"date_updated":"2020-07-14T12:47:19Z","checksum":"d71e528cff9c56f70ccc29dd7005257f","file_id":"6108","file_name":"2019_Light_LeFeber.pdf"}],"year":"2019","_id":"6102","article_number":"28","date_published":"2019-03-06T00:00:00Z","status":"public","type":"journal_article","publisher":"Springer Nature","date_created":"2019-03-17T22:59:13Z","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":"         8","isi":1,"fulldoi":"https://doi.org/10.1038/s41377-019-0124-3","citation":{"mla":"Le Feber, B., et al. “A Full Vectorial Mapping of Nanophotonic Light Fields.” <i>Light: Science and Applications</i>, vol. 8, no. 1, 28, Springer Nature, 2019, doi:<a href=\"https://doi.org/10.1038/s41377-019-0124-3\">10.1038/s41377-019-0124-3</a>.","chicago":"Le Feber, B., J.

Higher bandwidths require higher total optical power, but the power sent into the fibre is limited by optical nonlinearities within the fibre, and energy consumption by the light sources starts to become a substantial cost factor1. Optical frequency combs have been suggested to remedy this problem by generating numerous discrete, equidistant laser lines within a monolithic device; however, at present their stability and coherence allow them to operate only within small parameter ranges2,3,4. Here we show that a broadband frequency comb realized through the electro-optic effect within a high-quality whispering-gallery-mode resonator can operate at low microwave and optical powers. Unlike the usual third-order Kerr nonlinear optical frequency combs, our combs rely on the second-order nonlinear effect, which is much more efficient. Our result uses a fixed microwave signal that is mixed with an optical-pump signal to generate a coherent frequency comb with a precisely determined carrier separation. The resonant enhancement enables us to work with microwave powers that are three orders of magnitude lower than those in commercially available devices. We emphasize the practical relevance of our results to high rates of data communication. To circumvent the limitations imposed by nonlinear effects in optical communication fibres, one has to solve two problems: to provide a compact and fully integrated, yet high-quality and coherent, frequency comb generator; and to calculate nonlinear signal propagation in real time5. We report a solution to the first problem."}],"oa_version":"Preprint","doi":"10.1038/s41586-019-1110-x","day":"18","issue":"7752","publication":"Nature","volume":568,"title":"Resonant electro-optic frequency comb","scopus_import":"1","type":"journal_article","related_material":{"link":[{"url":"https://doi.org/10.1038/s41586-019-1220-5","relation":"erratum"}]},"status":"public","date_published":"2019-04-18T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1808.10608"}],"_id":"6348","year":"2019"},{"title":"Electro-optic frequency comb generation in lithium niobate whispering gallery mode resonators","author":[{"last_name":"Rueda Sanchez","orcid":"0000-0001-6249-5860","first_name":"Alfredo R","full_name":"Rueda Sanchez, Alfredo R","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Sedlmeir","full_name":"Sedlmeir, Florian","first_name":"Florian"},{"last_name":"Leuchs","full_name":"Leuchs, Gerd","first_name":"Gerd"},{"last_name":"Kuamri","full_name":"Kuamri, Madhuri","first_name":"Madhuri"},{"full_name":"Schwefel, Harald G.

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."}],"scopus_import":"1","title":"Electro-optic entanglement source for microwave to telecom quantum state transfer","year":"2019","file":[{"relation":"main_file","content_type":"application/pdf","date_created":"2019-12-09T08:25:06Z","creator":"dernst","file_id":"7157","file_name":"2019_NPJ_Rueda.pdf","checksum":"13e0ea1d4f9b5f5710780d9473364f58","date_updated":"2020-07-14T12:47:50Z","file_size":1580132,"access_level":"open_access"}],"_id":"7156","article_number":"108","date_published":"2019-12-01T00:00:00Z","status":"public","type":"journal_article"},{"author":[{"last_name":"Rueda Sanchez","orcid":"0000-0001-6249-5860","full_name":"Rueda Sanchez, Alfredo R","first_name":"Alfredo R","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Sedlmeir, Florian","first_name":"Florian","last_name":"Sedlmeir"},{"last_name":"Leuchs","first_name":"Gerd","full_name":"Leuchs, Gerd"},{"last_name":"Kumari","first_name":"Madhuri","full_name":"Kumari, Madhuri"},{"last_name":"Schwefel","first_name":"Harald G.L.","full_name":"Schwefel, Harald G.L."}],"title":"Resonant electro-optic frequency comb generation in lithium niobate disk resonator inside a microwave cavity","scopus_import":"1","status":"public","type":"conference","conference":{"location":"Waikoloa Beach, Hawaii (HI), United States","name":"NLO: Nonlinear Optics","end_date":"2019-07-19","start_date":"2019-07-15"},"date_published":"2019-07-15T00:00:00Z","language":[{"iso":"eng"}],"department":[{"_id":"JoFi"}],"date_updated":"2025-05-14T11:09:22Z","year":"2019","article_number":"NM2A.5","_id":"7233","quality_controlled":"1","month":"07","publication_identifier":{"isbn":["9781557528209"]},"article_processing_charge":"No","date_created":"2020-01-05T23:00:48Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publisher":"Optica Publishing Group","abstract":[{"text":"We demonstrate electro-optic frequency comb generation using a doubly resonant system comprising a whispering gallery mode disk resonator made of lithium niobate mounted inside a three dimensional copper cavity.

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"}],"oa_version":"Preprint","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_status":"published","project":[{"_id":"257EB838-B435-11E9-9278-68D0E5697425","name":"Hybrid Optomechanical Technologies","call_identifier":"H2020","grant_number":"732894"},{"grant_number":"758053","call_identifier":"H2020","name":"A Fiber Optic Transceiver for Superconducting Qubits","_id":"26336814-B435-11E9-9278-68D0E5697425"},{"grant_number":"707438","call_identifier":"H2020","name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics","_id":"258047B6-B435-11E9-9278-68D0E5697425"},{"name":"Coherent on-chip conversion of superconducting qubit signals from microwaves to optical frequencies","_id":"2671EB66-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","month":"06","article_processing_charge":"No","date_updated":"2026-11-08T23:30:30Z","language":[{"iso":"eng"}],"department":[{"_id":"JoFi"}],"ec_funded":1,"oa":1,"arxiv":1,"author":[{"last_name":"Barzanjeh","first_name":"Shabir","full_name":"Barzanjeh, Shabir","orcid":"0000-0003-0415-1423","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87"},{"id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","full_name":"Redchenko, Elena","first_name":"Elena","last_name":"Redchenko"},{"orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","first_name":"Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","last_name":"Peruzzo"},{"last_name":"Wulf","id":"45598606-F248-11E8-B48F-1D18A9856A87","first_name":"Matthias","full_name":"Wulf, Matthias","orcid":"0000-0001-6613-1378"},{"last_name":"Lewis","full_name":"Lewis, Dylan","first_name":"Dylan"},{"last_name":"Arnold","id":"3770C838-F248-11E8-B48F-1D18A9856A87","first_name":"Georg M","full_name":"Arnold, Georg M","orcid":"0000-0003-1397-7876"},{"last_name":"Fink","full_name":"Fink, Johannes M","first_name":"Johannes M","orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87"}],"isi":1,"intvolume":"       570","external_id":{"arxiv":["1809.05865"],"isi":["000472860000042"]},"page":"480-483","fulldoi":"https://doi.org/10.1038/s41586-019-1320-2","citation":{"ista":"Barzanjeh S, Redchenko E, Peruzzo M, Wulf M, Lewis D, Arnold GM, Fink JM. 2019.
