text: "This thesis explores advancements in quantum remote sensing and non-equilibrium
phase\r\ntransitions in the microwave regime, with a focus on dissipative phase
transitions and quantumenhanced sensing.\r\nIn the first project, I experimentally
studied photon blockade breakdown as a dissipative phase\r\ntransition in a zero-dimensional
cavity-qubit system. By defining an appropriate thermodynamic\r\nlimit, we demonstrated
that the observed bistability is a genuine signature of a first-order\r\nphase
transition in this system. This work provides insight into non-equilibrium quantum\r\ndynamics
and phase transitions in driven-dissipative open quantum systems.\r\nThe second
project focuses on the experimental realization of a phase-conjugate receiver
for\r\nquantum illumination (QI), a quantum sensing protocol that enhances target
detection in noisy\r\nenvironments using entangled light. While an ideal spontaneous
parametric down-conversion\r\n(SPDC) source and receiver could, in theory, provide
up to a 6 dB advantage over classical\r\nillumination, no such ideal receiver
exists. Instead, we explore an experimental realization of a\r\nphase-conjugate
receiver for QI in the microwave regime at millikelvin temperatures using a\r\nJosephson
parametric converter (JPC) as a source of continuous-variable Gaussian entangled\r\nsignal-idler
pairs, where a maximum 3 dB advantage is theoretically achievable. We investigate\r\nkey
experimental limitations that constrain practical QI performance, contributing
to the\r\ndevelopment of quantum-enhanced sensing.\r\nAdditionally, this thesis
presents efficient digital signal processing (DSP) techniques implemented in C++
and Python in collaboration with Przemysław Zieliński and Luka Drmić. These\r\nmethods,
optimized using the Intel Integrated Performance Primitives (IPP) library, have
been\r\nessential in data acquisition, noise filtering, and correlation analysis
across multiple research\r\nprojects. Although not real-time, these DSP techniques
significantly enhance the accuracy of\r\nquantum measurements.\r\nOverall, this
thesis advances quantum-enhanced sensing by establishing the thermodynamic\r\nlimit
in a single transmon-cavity system and experimentally exploring a phase-conjugate
receiver\r\nfor QI. These findings contribute to quantum metrology, particularly
for weak signal detection\r\nand remote sensing in noisy environments.\r\n"

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: 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: "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"

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: 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

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

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 Vπ
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.
