  text: Quantum entanglement is a key resource in currently developed quantum technologies.
    Sharing this fragile property between superconducting microwave circuits and optical
    or atomic systems would enable new functionalities, but this has been hindered
    by an energy scale mismatch of >104 and the resulting mutually imposed loss and
    noise. In this work, we created and verified entanglement between microwave and
    optical fields in a millikelvin environment. Using an optically pulsed superconducting
    electro-optical device, we show entanglement between propagating microwave and
    optical fields in the continuous variable domain. This achievement not only paves
    the way for entanglement between superconducting circuits and telecom wavelength
    light, but also has wide-ranging implications for hybrid quantum networks in the
    context of modularization, scaling, sensing, and cross-platform verification.

  text: Solid-state microwave systems offer strong interactions for fast quantum logic
    and sensing but photons at telecom wavelength are the ideal choice for high-density
    low-loss quantum interconnects. A general-purpose interface that can make use
    of single photon effects requires < 1 input noise quanta, which has remained elusive
    due to either low efficiency or pump induced heating. Here we demonstrate coherent
    electro-optic modulation on nanosecond-timescales with only 0.16+0.02−0.01 microwave
    input noise photons with a total bidirectional transduction efficiency of 8.7%
    (or up to 15% with 0.41+0.02−0.02), as required for near-term heralded quantum
    network protocols. The use of short and high-power optical pump pulses also enables
    near-unity cooperativity of the electro-optic interaction leading to an internal
    pure conversion efficiency of up to 99.5%. Together with the low mode occupancy
    this provides evidence for electro-optic laser cooling and vacuum amplification
    as predicted a decade ago.

  text: "Recent substantial advances in the feld of superconducting circuits have
    shown its\r\npotential as a leading platform for future quantum computing. In
    contrast to classical\r\ncomputers based on bits that are represented by a single
    binary value, 0 or 1, quantum\r\nbits (or qubits) can be in a superposition of
    both. Thus, quantum computers can store\r\nand handle more information at the
    same time and a quantum advantage has already\r\nbeen demonstrated for two types
    of computational tasks. Rapid progress in academic\r\nand industry labs accelerates
    the development of superconducting processors which may\r\nsoon fnd applications
    in complex computations, chemical simulations, cryptography, and\r\noptimization.
    Now that these machines are scaled up to tackle such problems the questions\r\nof
    qubit interconnects and networks becomes very relevant. How to route signals on-chip\r\nbetween
    diferent processor components? What is the most efcient way to entangle\r\nqubits?
    And how to then send and process entangled signals between distant cryostats\r\nhosting
    superconducting processors?\r\nIn this thesis, we are looking for solutions to
    these problems by studying the collective\r\nbehavior of superconducting qubit
    ensembles. We frst demonstrate on-demand tunable\r\ndirectional scattering of
    microwave photons from a pair of qubits in a waveguide. Such a\r\ndevice can route
    microwave photons on-chip with a high diode efciency. Then we focus\r\non studying
    ultra-strong coupling regimes between light (microwave photons) and matter\r\n(superconducting
    qubits), a regime that could be promising for extremely fast multi-qubit\r\nentanglement
    generation. Finally, we show coherent pulse storage and periodic revivals\r\nin
    a fve qubit ensemble strongly coupled to a resonator. Such a reconfgurable storage\r\ndevice
    could be used as part of a quantum repeater that is needed for longer-distance\r\nquantum
    communication.\r\nThe achieved high degree of control over multi-qubit ensembles
    highlights not only the\r\nbeautiful physics of circuit quantum electrodynamics,
    it also represents the frst step\r\ntoward new quantum simulation and communication
    methods, and certain techniques\r\nmay also fnd applications in future superconducting
    quantum computing hardware.\r\n"

    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: 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: '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: 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.
