  text: 'State-of-the-art transmon qubits rely on large capacitors, which systematically
    improve their coherence due to reduced surface-loss participation. However, this
    approach increases both the footprint and the parasitic cross-coupling and is
    ultimately limited by radiation losses—a potential roadblock for scaling up quantum
    processors to millions of qubits. In this work we present transmon qubits with
    sizes as low as 36 × 39 µm2 with  100-nm-wide vacuum-gap capacitors that are micromachined
    from commercial silicon-on-insulator wafers and shadow evaporated with aluminum.
    We achieve a vacuum participation ratio up to 99.6% in an in-plane design that
    is compatible with standard coplanar circuits. Qubit relaxationtime measurements
    for small gaps with high zero-point electric field variance of up to 22 V/m reveal
    a double exponential decay indicating comparably strong qubit interaction with
    long-lived two-level systems. The exceptionally high selectivity of up to 20 dB
    to the superconductor-vacuum interface allows us to precisely back out the sub-single-photon
    dielectric loss tangent of aluminum oxide previously exposed to ambient conditions.
    In terms of future scaling potential, we achieve a ratio of qubit quality factor
    to a footprint area equal to 20 µm−2, which is comparable with the highest T1
    devices relying on larger geometries, a value that could improve substantially
    for lower surface-loss superconductors. '

  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 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: 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: 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: 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 has been significant interest recently in using complex quantum systems
    to create effective nonreciprocal dynamics. 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.

  text: Nonreciprocal circuit elements form an integral part of modern measurement
    and communication systems. Mathematically they require breaking of time-reversal
    symmetry, typically achieved using magnetic materials and more recently using
    the quantum Hall effect, parametric permittivity modulation or Josephson nonlinearities.
    Here we demonstrate an on-chip magnetic-free circulator based on reservoir-engineered
    electromechanic interactions. Directional circulation is achieved with controlled
    phase-sensitive interference of six distinct electro-mechanical signal conversion
    paths. The presented circulator is compact, its silicon-on-insulator platform
    is compatible with both superconducting qubits and silicon photonics, and its
    noise performance is close to the quantum limit. With a high dynamic range, a
    tunable bandwidth of up to 30 MHz and an in situ reconfigurability as beam splitter
    or wavelength converter, it could pave the way for superconducting qubit processors
    with multiplexed on-chip signal processing and readout.

  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.
