  text: "The photon blockade breakdown in a continuously driven cavity QED system
    has been proposed as a prime example for a first-order driven-dissipative quantum
    phase transition. However, the predicted scaling from a microscopic behavior—dominated
    by quantum fluctuations—to a macroscopic one—characterized by stable phases—and
    the associated exponents and phase diagram have not been observed so far. In this
    work we couple a single transmon qubit with a fixed coupling strength \U0001D454
    to a superconducting cavity that is in situ bandwidth \U0001D705 tunable to controllably
    approach this thermodynamic limit. Even though the system remains microscopic,
    we observe its behavior becoming increasingly macroscopic as a function of \U0001D454/\U0001D705.
    For the highest realized \U0001D454/\U0001D705 of approximately 287, the system
    switches with a characteristic timescale as long as 6 s between a bright coherent
    state with approximately 8×103 intracavity photons and the vacuum state. This
    exceeds the microscopic timescales by 6 orders of magnitude and approaches the
    perfect hysteresis expected between two macroscopic attractors in the thermodynamic
    limit. These findings and interpretation are qualitatively supported by neoclassical
    theory and large-scale quantum-jump Monte Carlo simulations. Besides shedding
    more light on driven-dissipative physics in the limit of strong light-matter coupling,
    this system might also find applications in quantum sensing and metrology."

  text: "Superconductor-semiconductor heterostructures currently capture a significant
    amount of research interest and they serve as the physical platform in many proposals
    towards topological quantum computation.\r\nDespite being under extensive investigations,
    historically using transport techniques, the basic properties of the interface
    between the superconductor and the semiconductor remain to be understood.\r\n\r\nIn
    this thesis, two separate studies on the Al-InAs heterostructures are reported
    with the first focusing on the physics of the material motivated by the emergence
    of a new phase, the Bogoliubov-Fermi surface. \r\nThe second focuses on a technological
    application, a gate-tunable Josephson parametric amplifier.\r\n\r\nIn the first
    study, we investigate the hypothesized unconventional nature of the induced superconductivity
    at the interface between the Al thin film and the InAs quantum well.\r\nWe embed
    a two-dimensional Al-InAs hybrid system in a resonant microwave circuit allowing
    measurements of change in inductance.\r\nThe behaviour of the resonance in a range
    of temperature and in-plane magnetic field has been studied and compared with
    the theory of conventional s-wave superconductor and a two-component theory that
    includes both contribution of the $s$-wave pairing in Al and the intraband $p
    \\pm ip$ pairing in InAs.\r\nMeasuring the temperature dependence of resonant
    frequency, no discrepancy is found between data and the conventional theory.\r\nWe
    observe the breakdown of superconductivity due to an applied magnetic field which
    contradicts the conventional theory.\r\nIn contrast, the data can be captured
    quantitatively by fitting to a two-component model.\r\nWe find the evidence of
    the intraband $p \\pm ip$ pairing in the InAs and the emergence of the Bogoliubov-Fermi
    surfaces due to magnetic field with the characteristic value $B^* = 0.33~\\mathrm{T}$.\r\nFrom
    the fits, the sheet resistance of Al, the carrier density and mobility in InAs
    are determined.\r\nBy systematically studying the anisotropy of the circuit response,
    we find weak anisotropy for $B < B^*$ and increasingly strong anisotropy for $B
    > B^*$ resulting in a pronounced two-lobe structure in polar plot of frequency
    versus field angle.\r\nStrong resemblance between the field dependence of dissipation
    and superfluid density hints at a hidden signature of the Bogoliubov-Fermi surface
    that is burried in the dissipation data.\r\n\r\nIn the second study, we realize
    a parametric amplifier with a Josephson field effect transistor as the active
    element.\r\nThe device's modest construction consists of a gated SNS weak link
    embedded at the center of a coplanar waveguide resonator.\r\nBy applying a gate
    voltage, the resonant frequency is field-effect tunable over a range of 2 GHz.\r\nModelling
    the JoFET minimally as a parallel RL circuit, the dissipation introduced by the
    JoFET can be quantitatively related to the gate voltage.\r\nWe observed gate-tunable
    Kerr nonlinearity qualitatively in line with expectation.\r\nThe JoFET amplifier
    has 20 dB of gain, 4 MHz of instantaneous bandwidth, and a 1dB compression point
    of -125.5 dBm when operated at a fixed resonant frequency.\r\nIn general, the
    signal-to-noise ratio is improved by 5-7 dB when the JoFET amplifier is activated
    compared.\r\nThe noise of the measurement chain and insertion loss of relevant
    circuit elements are calibrated to determine the expected and the real noise performance
    of the JoFET amplifier.\r\nAs a quantification of the noise performance, the measured
    total input-referred noise of the JoFET amplifier is in good agreement with the
    estimated expectation which takes device loss into account.\r\nWe found that the
    noise performance of the device reported in this document approaches one photon
    of total input-referred added noise which is the quantum limit imposed in nondegenerate
    parametric amplifier."

  text: Superconductor-semiconductor hybrid devices are at the heart of several proposed
    approaches to quantum information processing, but their basic properties remain
    to be understood. We embed a twodimensional Al-InAs hybrid system in a resonant
    microwave circuit, probing the breakdown of superconductivity due to an applied
    magnetic field. We find a fingerprint from the two-component nature of the hybrid
    system, and quantitatively compare with a theory that includes the contribution
    of intraband p±ip pairing in the InAs, as well as the emergence of Bogoliubov-Fermi
    surfaces due to magnetic field. Separately resolving the Al and InAs contributions
    allows us to determine the carrier density and mobility in the InAs.

  text: Superconductor-semiconductor hybrids are platforms for realizing effective
    p-wave superconductivity. Spin-orbit coupling, combined with the proximity effect,
    causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and
    application of magnetic field can then result in transitions to the normal state,
    partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes.
    Experimentally probing the hybrid superconductor-semiconductor interface is challenging
    due to the shunting effect of the conventional superconductor. Consequently, the
    nature of induced pairing remains an open question. Here, we use the circuit quantum
    electrodynamics architecture to probe induced superconductivity in a two dimensional
    Al-InAs hybrid system. We observe a strong suppression of superfluid density and
    enhanced dissipation driven by magnetic field, which cannot be accounted for by
    the depairing theory of an s-wave superconductor. These observations are explained
    by a picture of independent intraband p±ip superconductors giving way to partial
    Bogoliubov Fermi surfaces, and allow for the first characterization of key properties
    of the hybrid superconducting system.
