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.","lang":"eng"}],"doi":"10.1103/prxquantum.1.020315","day":"23","isi":1,"external_id":{"isi":["000674680100001"]},"date_updated":"2024-10-29T09:11:05Z","citation":{"short":"W.J.

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.","lang":"eng"}],"citation":{"chicago":"Lambert, Nicholas J., Alfredo R Rueda Sanchez, Florian Sedlmeir, and Harald G.

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."}],"date_updated":"2024-08-07T07:11:55Z","year":"2019","citation":{"chicago":"Rueda Sanchez, Alfredo R, William J Hease, Shabir Barzanjeh, and Johannes M Fink. “Electro-Optic Entanglement Source for Microwave to Telecom Quantum State Transfer.” Npj Quantum Information.

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. Devices with hypersonic mechanical frequencies provide a natural pathway for integration with Josephson junction quantum circuits, a leading quantum computing technology, and nanophotonic systems capable of optical networking and distributing quantum information.","lang":"eng"}],"date_updated":"2023-08-24T14:48:08Z","citation":{"apa":"Kalaee, M., Mirhosseini, M., Dieterle, P.

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"}],"doi":"10.1038/s41377-019-0124-3","arxiv":1,"day":"06","language":[{"iso":"eng"}],"publication":"Light: Science and Applications","has_accepted_license":"1","month":"03","article_number":"28","oa_version":"Published Version","status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file":[{"date_updated":"2020-07-14T12:47:19Z","content_type":"application/pdf","file_name":"2019_Light_LeFeber.pdf","date_created":"2019-03-18T08:08:22Z","file_size":1119947,"checksum":"d71e528cff9c56f70ccc29dd7005257f","file_id":"6108","creator":"dernst","relation":"main_file","access_level":"open_access"}],"date_published":"2019-03-06T00:00:00Z","type":"journal_article","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":1,"publication_identifier":{"issn":["20955545"],"eissn":["20477538"]}},{"volume":568,"abstract":[{"text":"High-speed optical telecommunication is enabled by wavelength-division multiplexing, whereby hundreds of individually stabilized lasers encode information within a single-mode optical fibre. 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.","lang":"eng"}],"arxiv":1,"doi":"10.1038/s41586-019-1110-x","day":"18","isi":1,"external_id":{"isi":["000464950700053"],"arxiv":["1808.10608"]},"date_updated":"2023-08-25T10:15:25Z","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.","lang":"eng"}],"citation":{"chicago":"Barzanjeh, Shabir, Elena Redchenko, Matilda Peruzzo, Matthias Wulf, Dylan Lewis, Georg M Arnold, and Johannes M Fink. “Stationary Entangled Radiation from Micromechanical Motion.” Nature.

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"}],"day":"20","doi":"10.1364/OPTICA.5.001210","external_id":{"isi":["000447853100007"]},"isi":1,"year":"2018","citation":{"mla":"Botello, Gabriel, et al. “Sensitivity Limits of Millimeter-Wave Photonic Radiometers Based on Efficient Electro-Optic Upconverters.” Optica, vol. 5, no. 10, 2018, pp. 1210–19, doi:10.1364/OPTICA.5.001210.","short":"G.

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."}],"year":"2018","citation":{"ama":"Xuereb A, Aquilina M, Barzanjeh S.

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"}],"volume":120,"scopus_import":"1","_id":"436","issue":"6","author":[{"first_name":"Shabir","last_name":"Barzanjeh","orcid":"0000-0003-0415-1423","full_name":"Barzanjeh, Shabir","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Matteo","last_name":"Aquilina","full_name":"Aquilina, Matteo"},{"last_name":"Xuereb","first_name":"André","full_name":"Xuereb, André"}],"date_created":"2018-12-11T11:46:28Z","article_processing_charge":"No","department":[{"_id":"JoFi"}],"publication_status":"published","intvolume":" 120","title":"Manipulating the flow of thermal noise in quantum devices","ec_funded":1,"quality_controlled":"1","publisher":"American Physical Society","type":"journal_article","date_published":"2018-02-07T00:00:00Z","publist_id":"7387","oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1706.09051"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","related_material":{"link":[{"url":"https://ist.ac.at/en/news/interference-as-a-new-method-for-cooling-quantum-devices/","description":"News on IST Homepage","relation":"press_release"}]},"status":"public","publication":"Physical Review Letters","project":[{"grant_number":"732894","name":"Hybrid Optomechanical Technologies","call_identifier":"H2020","_id":"257EB838-B435-11E9-9278-68D0E5697425"},{"name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics SUPEREOM","grant_number":"707438","call_identifier":"H2020","_id":"258047B6-B435-11E9-9278-68D0E5697425"}],"oa_version":"Preprint","article_number":"060601 ","month":"02","language":[{"iso":"eng"}]},{"ddc":["539"],"volume":7,"isi":1,"external_id":{"isi":["000397450500001"]},"date_updated":"2023-09-20T11:33:07Z","year":"2017","citation":{"ieee":"J.

In second-order transitions this change is abrupt at a critical point, whereas in first-order transitions the two phases can coexist in a critical hysteresis domain. Here, we report the observation of a first-order dissipative quantum phase transition in a driven circuit quantum electrodynamics system. It takes place when the photon blockade of the driven cavity-atom system is broken by increasing the drive power. The observed experimental signature is a bimodal phase space distribution with varying weights controlled by the drive strength. Our measurements show an improved stabilization of the classical attractors up to the millisecond range when the size of the quantum system is increased from one to three artificial atoms. The formation of such robust pointer states could be used for new quantum measurement schemes or to investigate multiphoton phases of finite-size, nonlinear, open quantum systems."}],"doi":"10.1103/PhysRevX.7.011012","day":"31","file_date_updated":"2018-12-12T10:12:52Z","quality_controlled":"1","publisher":"American Physical Society","author":[{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M","last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M"},{"full_name":"Dombi, András","last_name":"Dombi","first_name":"András"},{"last_name":"Vukics","first_name":"András","full_name":"Vukics, András"},{"last_name":"Wallraff","first_name":"Andreas","full_name":"Wallraff, Andreas"},{"first_name":"Peter","last_name":"Domokos","full_name":"Domokos, Peter"}],"issue":"1","_id":"1114","scopus_import":"1","pubrep_id":"753","title":"Observation of the photon blockade breakdown phase transition","intvolume":" 7","publication_status":"published","department":[{"_id":"JoFi"}],"date_created":"2018-12-11T11:50:13Z","article_processing_charge":"Yes","status":"public","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"relation":"main_file","access_level":"open_access","creator":"system","file_id":"4972","file_size":1172926,"date_created":"2018-12-12T10:12:52Z","content_type":"application/pdf","file_name":"IST-2017-753-v1+1_PhysRevX.7.011012.pdf","date_updated":"2018-12-12T10:12:52Z"}],"date_published":"2017-01-31T00:00:00Z","type":"journal_article","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":1,"publist_id":"6252","publication_identifier":{"issn":["21603308"]},"language":[{"iso":"eng"}],"publication":"Physical Review X","has_accepted_license":"1","month":"01","article_number":"011012","oa_version":"Published Version"},{"date_published":"2017-07-01T00:00:00Z","type":"journal_article","publist_id":"6857","oa":1,"publication_identifier":{"issn":["00036951"]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1703.10195"}],"publication":"Applied Physics Letters","month":"07","article_number":"042603","oa_version":"Submitted Version","language":[{"iso":"eng"}],"isi":1,"external_id":{"isi":["000406779700031"]},"date_updated":"2023-09-27T12:13:36Z","year":"2017","citation":{"chicago":"Keller, Andrew J, Paul Dieterle, Michael Fang, Brett Berger, Johannes M Fink, and Oskar Painter. “Al Transmon Qubits on Silicon on Insulator for Quantum Device Integration.” Applied Physics Letters.

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.

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.
