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. Our results highlight the opportunities and challenges in the way toward a first room-temperature application of microwave quantum circuits.","lang":"eng"}],"date_created":"2020-05-31T22:00:49Z","publication_status":"published","external_id":{"arxiv":["1908.03058"],"isi":["000531171100045"]},"_id":"7910","issue":"19","quality_controlled":"1","date_published":"2020-05-06T00:00:00Z","intvolume":" 6","volume":6,"author":[{"first_name":"Shabir","orcid":"0000-0003-0415-1423","full_name":"Barzanjeh, Shabir","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","last_name":"Barzanjeh"},{"last_name":"Pirandola","full_name":"Pirandola, S.","first_name":"S."},{"last_name":"Vitali","first_name":"D","full_name":"Vitali, D"},{"last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M"}],"type":"journal_article","citation":{"chicago":"Barzanjeh, Shabir, S.

Electro-opto-mechanical devices are currently one of the leading approaches to realize ultra-sensitive, low-loss transducers for an emerging quantum information technology. Here we present an on-chip microwave frequency converter based on a planar aluminum on silicon nitride platform that is compatible with slot-mode coupled photonic crystal cavities. 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. Such a silicon nitride based transducer is in situ reconfigurable and could be used for on-chip classical and quantum signal routing and filtering, both for microwave and hybrid microwave-optical applications."}],"date_created":"2020-06-29T07:59:35Z","publication_status":"published","external_id":{"isi":["000539300800001"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.1088/2058-9565/ab8dce","day":"25","publication":"Quantum Science and Technology","ec_funded":1,"article_type":"original","article_number":"034011","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["20589565"]},"oa":1,"department":[{"_id":"JoFi"}],"year":"2020","project":[{"_id":"26336814-B435-11E9-9278-68D0E5697425","name":"A Fiber Optic Transceiver for Superconducting Qubits","grant_number":"758053","call_identifier":"H2020"},{"call_identifier":"FWF","grant_number":"F07105","name":"Integrating superconducting quantum circuits","_id":"26927A52-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","grant_number":"732894","name":"Hybrid Optomechanical Technologies","_id":"257EB838-B435-11E9-9278-68D0E5697425"},{"name":"Hybrid Semiconductor - Superconductor Quantum Devices","_id":"2622978C-B435-11E9-9278-68D0E5697425"}],"title":"Efficient microwave frequency conversion mediated by a photonics compatible silicon nitride nanobeam oscillator"},{"abstract":[{"text":"In this paper we present a room temperature radiometer that can eliminate the need of using cryostats in satellite payload reducing its weight and improving reliability.

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.

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.","lang":"eng"}],"publication_status":"published","external_id":{"isi":["000502996200003"],"arxiv":["1909.01470"]},"date_created":"2019-12-09T08:18:56Z","_id":"7156","quality_controlled":"1","date_published":"2019-12-01T00:00:00Z","intvolume":" 5","author":[{"last_name":"Rueda Sanchez","first_name":"Alfredo R","orcid":"0000-0001-6249-5860","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87","full_name":"Rueda Sanchez, Alfredo R"},{"first_name":"William J","orcid":"0000-0001-9868-2166","id":"29705398-F248-11E8-B48F-1D18A9856A87","full_name":"Hease, William J","last_name":"Hease"},{"full_name":"Barzanjeh, Shabir","orcid":"0000-0003-0415-1423","first_name":"Shabir","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","last_name":"Barzanjeh"},{"last_name":"Fink","full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M"}],"volume":5,"type":"journal_article","citation":{"short":"A.R.

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."}],"date_created":"2019-03-17T22:59:13Z","external_id":{"arxiv":["1803.10145"],"isi":["000460470700004"]},"publication_status":"published","scopus_import":"1","author":[{"full_name":"Le Feber, B.","first_name":"B.","last_name":"Le Feber"},{"last_name":"Sipe","first_name":"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."}],"scopus_import":"1","related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1038/s41586-019-1220-5"}]},"oa_version":"Preprint","date_updated":"2023-08-25T10:15:25Z","month":"04","status":"public","isi":1,"article_processing_charge":"No","publisher":"Springer Nature","citation":{"ieee":"A.

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."}],"external_id":{"arxiv":["1809.05865"],"isi":["000472860000042"]},"publication_status":"published","date_created":"2019-07-07T21:59:20Z","_id":"6609","quality_controlled":"1","date_published":"2019-06-27T00:00:00Z","intvolume":" 570","volume":570,"author":[{"last_name":"Barzanjeh","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","first_name":"Shabir","orcid":"0000-0003-0415-1423","full_name":"Barzanjeh, Shabir"},{"last_name":"Redchenko","id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","full_name":"Redchenko, Elena","first_name":"Elena"},{"full_name":"Peruzzo, Matilda","first_name":"Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3415-4628","last_name":"Peruzzo"},{"last_name":"Wulf","first_name":"Matthias","full_name":"Wulf, Matthias","id":"45598606-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6613-1378"},{"last_name":"Lewis","full_name":"Lewis, Dylan","first_name":"Dylan"},{"last_name":"Arnold","full_name":"Arnold, Georg M","first_name":"Georg M","id":"3770C838-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1397-7876"},{"full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","first_name":"Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink"}],"page":"480-483","type":"journal_article","citation":{"ieee":"S.

Quantum states, including entangled states, are fragile and easily disturbed by excessive thermal noise. Here we address the question of whether it is possible to create non-reciprocal devices that encourage the flow of thermal noise towards or away from a particular quantum device in a network. Our work makes use of the cascaded systems formalism to answer this question in the affirmative, showing how a three-port device can be used as an effective thermal transistor, and illustrates how this formalism maps onto an experimentally-realisable optomechanical system. Our results pave the way to more resilient quantum devices and to the use of thermal noise as a resource.","lang":"eng"}],"external_id":{"isi":["000453298500019"],"arxiv":["1806.01000"]},"date_created":"2018-12-11T11:44:55Z","publication_status":"published"},{"main_file_link":[{"open_access":"1","url":"www.doi.org/10.1364/OPTICA.5.001210 "}],"title":"Sensitivity limits of millimeter-wave photonic radiometers based on efficient electro-optic upconverters","year":"2018","department":[{"_id":"JoFi"}],"article_type":"original","oa":1,"language":[{"iso":"eng"}],"publication_identifier":{"issn":["23342536"]},"doi":"10.1364/OPTICA.5.001210","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"Optica","day":"20","scopus_import":"1","publication_status":"published","external_id":{"isi":["000447853100007"]},"date_created":"2018-12-11T11:44:12Z","abstract":[{"text":"Conventional ultra-high sensitivity detectors in the millimeter-wave range are usually cooled as their own thermal noise at room temperature would mask the weak received radiation. The need for cryogenic systems increases the cost and complexity of the instruments, hindering the development of, among others, airborne and space applications. In this work, the nonlinear parametric upconversion of millimeter-wave radiation to the optical domain inside high-quality (Q) lithium niobate whispering-gallery mode (WGM) resonators is proposed for ultra-low noise detection. We experimentally demonstrate coherent upconversion of millimeter-wave signals to a 1550 nm telecom carrier, with a photon conversion efficiency surpassing the state-of-the-art by 2 orders of magnitude. Moreover, a theoretical model shows that the thermal equilibrium of counterpropagating WGMs is broken by overcoupling the millimeter-wave WGM, effectively cooling the upconverted mode and allowing ultra-low noise detection. By theoretically estimating the sensitivity of a correlation radiometer based on the presented scheme, it is found that room-temperature radiometers with better sensitivity than state-of-the-art high-electron-mobility transistor (HEMT)-based radiometers can be designed. This detection paradigm can be used to develop room-temperature instrumentation for radio astronomy, earth observation, planetary missions, and imaging systems.","lang":"eng"}],"quality_controlled":"1","issue":"10","_id":"22","intvolume":" 5","date_published":"2018-10-20T00:00:00Z","page":"1210 - 1219","volume":5,"author":[{"first_name":"Gabriel","full_name":"Botello, Gabriel","last_name":"Botello"},{"full_name":"Sedlmeir, Florian","first_name":"Florian","last_name":"Sedlmeir"},{"last_name":"Rueda Sanchez","first_name":"Alfredo R","full_name":"Rueda Sanchez, Alfredo R","orcid":"0000-0001-6249-5860","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Abdalmalak","full_name":"Abdalmalak, Kerlos","first_name":"Kerlos"},{"full_name":"Brown, Elliott","first_name":"Elliott","last_name":"Brown"},{"first_name":"Gerd","full_name":"Leuchs, Gerd","last_name":"Leuchs"},{"full_name":"Preu, Sascha","first_name":"Sascha","last_name":"Preu"},{"full_name":"Segovia Vargas, Daniel","first_name":"Daniel","last_name":"Segovia Vargas"},{"last_name":"Strekalov","first_name":"Dmitry","full_name":"Strekalov, Dmitry"},{"last_name":"Munoz","full_name":"Munoz, Luis","first_name":"Luis"},{"last_name":"Schwefel","full_name":"Schwefel, Harald","first_name":"Harald"}],"type":"journal_article","article_processing_charge":"No","citation":{"chicago":"Botello, Gabriel, Florian Sedlmeir, Alfredo R Rueda Sanchez, Kerlos Abdalmalak, Elliott Brown, Gerd Leuchs, Sascha Preu, et al. “Sensitivity Limits of Millimeter-Wave Photonic Radiometers Based on Efficient Electro-Optic Upconverters.” Optica, 2018. https://doi.org/10.1364/OPTICA.5.001210.","ieee":"G.

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."}],"publication_status":"published","date_created":"2018-12-11T11:46:28Z","external_id":{"arxiv":["1706.09051"],"isi":["000424382100004"]},"scopus_import":"1","volume":120,"author":[{"last_name":"Barzanjeh","first_name":"Shabir","orcid":"0000-0003-0415-1423","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","full_name":"Barzanjeh, Shabir"},{"full_name":"Aquilina, Matteo","first_name":"Matteo","last_name":"Aquilina"},{"full_name":"Xuereb, André","first_name":"André","last_name":"Xuereb"}],"date_published":"2018-02-07T00:00:00Z","intvolume":" 120","_id":"436","issue":"6","quality_controlled":"1","language":[{"iso":"eng"}],"oa":1,"ec_funded":1,"article_number":"060601 ","day":"07","publication":"Physical Review Letters","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","doi":"10.1103/PhysRevLett.120.060601","title":"Manipulating the flow of thermal noise in quantum devices","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1706.09051"}],"arxiv":1,"department":[{"_id":"JoFi"}],"year":"2018","project":[{"grant_number":"732894","_id":"257EB838-B435-11E9-9278-68D0E5697425","name":"Hybrid Optomechanical Technologies","call_identifier":"H2020"},{"grant_number":"707438","_id":"258047B6-B435-11E9-9278-68D0E5697425","name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics SUPEREOM","call_identifier":"H2020"}]},{"main_file_link":[{"url":"https://arxiv.org/pdf/1612.07061.pdf","open_access":"1"}],"title":"Optomechanical proposal for monitoring microtubule mechanical vibrations","year":"2017","department":[{"_id":"JoFi"}],"project":[{"call_identifier":"H2020","_id":"258047B6-B435-11E9-9278-68D0E5697425","name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics","grant_number":"707438"}],"ec_funded":1,"article_number":"012404","language":[{"iso":"eng"}],"publication_identifier":{"issn":["24700045"]},"oa":1,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","doi":"10.1103/PhysRevE.96.012404","publication":" Physical Review E Statistical Nonlinear and Soft Matter Physics ","day":"12","scopus_import":1,"abstract":[{"text":"Microtubules provide the mechanical force required for chromosome separation during mitosis. 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"}],"publication_status":"published","date_created":"2018-12-11T11:48:00Z","_id":"700","quality_controlled":"1","issue":"1","intvolume":" 96","date_published":"2017-07-12T00:00:00Z","author":[{"last_name":"Barzanjeh","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0415-1423","first_name":"Shabir","full_name":"Barzanjeh, Shabir"},{"full_name":"Salari, Vahid","first_name":"Vahid","last_name":"Salari"},{"last_name":"Tuszynski","full_name":"Tuszynski, Jack","first_name":"Jack"},{"last_name":"Cifra","first_name":"Michal","full_name":"Cifra, Michal"},{"full_name":"Simon, Christoph","first_name":"Christoph","last_name":"Simon"}],"volume":96,"type":"journal_article","citation":{"chicago":"Barzanjeh, Shabir, Vahid Salari, Jack Tuszynski, Michal Cifra, and Christoph Simon. “Optomechanical Proposal for Monitoring Microtubule Mechanical Vibrations.” Physical Review E Statistical Nonlinear and Soft Matter Physics .
