  text: Quantum illumination uses entangled signal-idler photon pairs to boost the
    detection efficiency of low-reflectivity objects in environments with bright thermal
    noise. 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.

  text: Microelectromechanical systems and integrated photonics provide the basis
    for many reliable and compact circuit elements in modern communication systems.
    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.

  text: "Superconductor insulator transition in transverse magnetic field is studied
    in the highly disordered MoC film with the product of the Fermi momentum and the
    mean free path kF*l close to unity. 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 \U0001D435\U0001D4502,
    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 \U0001D435\U0001D4502 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 \U0001D435\U0001D4502."

  text: Quantum illumination is a sensing technique that employs entangled signal-idler
    beams to improve the detection efficiency of low-reflectivity objects in environments
    with large thermal noise. 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.

  text: Quantum transduction, the process of converting quantum signals from one form
    of energy to another, is an important area of quantum science and technology.
    The present perspective article reviews quantum transduction between microwave
    and optical photons, an area that has recently seen a lot of activity and progress
    because of its relevance for connecting superconducting quantum processors over
    long distances, among other applications. Our review covers the leading approaches
    to achieving such transduction, with an emphasis on those based on atomic ensembles,
    opto-electro-mechanics, and electro-optics. We briefly discuss relevant metrics
    from the point of view of different applications, as well as challenges for the
    future.

  text: Quantum information technology based on solid state qubits has created much
    interest in converting quantum states from the microwave to the optical domain.
    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.

  text: 'The superconducting circuit community has recently discovered the promising
    potential of superinductors. These circuit elements have a characteristic impedance
    exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of
    ground state charge fluctuations. 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. '

  text: Practical quantum networks require low-loss and noise-resilient optical interconnects
    as well as non-Gaussian resources for entanglement distillation and distributed
    quantum computation. The latter could be provided by superconducting circuits
    but existing solutions to interface the microwave and optical domains lack either
    scalability or efficiency, and in most cases the conversion noise is not known.
    In this work we utilize the unique opportunities of silicon photonics, cavity
    optomechanics and superconducting circuits to demonstrate a fully integrated,
    coherent transducer interfacing the microwave X and the telecom S bands with a
    total (internal) bidirectional transduction efficiency of 1.2% (135%) at millikelvin
    temperatures. The coupling relies solely on the radiation pressure interaction
    mediated by the femtometer-scale motion of two silicon nanobeams reaching a <jats:italic>V</jats:italic><jats:sub><jats:italic>π</jats:italic></jats:sub>
    as low as 16 μV for sub-nanowatt pump powers. Without the associated optomechanical
    gain, we achieve a total (internal) pure conversion efficiency of up to 0.019%
    (1.6%), relevant for future noise-free operation on this qubit-compatible platform.

  text: "Microwave photonics lends the advantages of fiber optics to electronic sensing
    and communication systems. 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."

  text: Recent technical developments in the fields of quantum electromechanics and
    optomechanics have spawned nanoscale mechanical transducers with the sensitivity
    to measure mechanical displacements at the femtometre scale and the ability to
    convert electromagnetic signals at the single photon level. 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.

  text: 'Light is a union of electric and magnetic fields, and nowhere is the complex
    relationship between these fields more evident than in the near fields of nanophotonic
    structures. 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.'

  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.'

  text: We propose an efficient microwave-photonic modulator as a resource for stationary
    entangled microwave-optical fields and develop the theory for deterministic entanglement
    generation and quantum state transfer in multi-resonant electro-optic systems.
    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.

  text: We prove that the observable telegraph signal accompanying the bistability
    in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings
    model is the finite-size precursor of what in the thermodynamic limit is a genuine
    first-order phase transition. We construct a finite-size scaling of the system
    parameters to a well-defined thermodynamic limit, in which the system remains
    the same microscopic system, but the telegraph signal becomes macroscopic both
    in its timescale and intensity. The existence of such a finite-size scaling completes
    and justifies the classification of the photon-blockade-breakdown effect as a
    first-order dissipative quantum phase transition.

  text: Mechanical systems facilitate the development of a hybrid quantum technology
    comprising electrical, optical, atomic and acoustic degrees of freedom1, and entanglement
    is essential to realize quantum-enabled devices. 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.

  text: In this paper, we discuss biological effects of electromagnetic (EM) fields
    in the context of cancer biology. In particular, we review the nanomechanical
    properties of microtubules (MTs), the latter being one of the most successful
    targets for cancer therapy. We propose an investigation on the coupling of electromagnetic
    radiation to mechanical vibrations of MTs as an important basis for biological
    and medical applications. In our opinion, optomechanical methods can accurately
    monitor and control the mechanical properties of isolated MTs in a liquid environment.
    Consequently, studying nanomechanical properties of MTs may give useful information
    for future applications to diagnostic and therapeutic technologies involving non-invasive
    externally applied physical fields. For example, electromagnetic fields or high
    intensity ultrasound can be used therapeutically avoiding harmful side effects
    of chemotherapeutic agents or classical radiation therapy.

  text: There is currently significant interest in operating devices in the quantum
    regime, where their behaviour cannot be explained through classical mechanics.
    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.
