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: The ability to control the direction of scattered light is crucial to provide
flexibility and scalability for a wide range of on-chip applications, such as
integrated photonics, quantum information processing, and nonlinear optics. Tunable
directionality can be achieved by applying external magnetic fields that modify
optical selection rules, by using nonlinear effects, or interactions with vibrations.
However, these approaches are less suitable to control microwave photon propagation
inside integrated superconducting quantum devices. Here, we demonstrate on-demand
tunable directional scattering based on two periodically modulated transmon qubits
coupled to a transmission line at a fixed distance. By changing the relative phase
between the modulation tones, we realize unidirectional forward or backward photon
scattering. Such an in-situ switchable mirror represents a versatile tool for
intra- and inter-chip microwave photonic processors. In the future, a lattice
of qubits can be used to realize topological circuits that exhibit strong nonreciprocity
or chirality.

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: There are two elementary superconducting qubit types that derive directly
from the quantum harmonic oscillator. In one, the inductor is replaced by a nonlinear
Josephson junction to realize the widely used charge qubits with a compact phase
variable and a discrete charge wave function. In the other, the junction is added
in parallel, which gives rise to an extended phase variable, continuous wave functions,
and a rich energy-level structure due to the loop topology. While the corresponding
rf superconducting quantum interference device Hamiltonian was introduced as a
quadratic quasi-one-dimensional potential approximation to describe the fluxonium
qubit implemented with long Josephson-junction arrays, in this work we implement
it directly using a linear superinductor formed by a single uninterrupted aluminum
wire. We present a large variety of qubits, all stemming from the same circuit
but with drastically different characteristic energy scales. This includes flux
and fluxonium qubits but also the recently introduced quasicharge qubit with strongly
enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.
The use of a geometric inductor results in high reproducibility of the inductive
energy as guaranteed by top-down lithography—a key ingredient for intrinsically
protected superconducting qubits.

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.

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: 'Spontaneous emission spectra of two initially excited closely spaced identical
atoms are very sensitive to the strength and the direction of the applied magnetic
field. We consider the relevant schemes that ensure the determination of the mutual
spatial orientation of the atoms and the distance between them by entirely optical
means. A corresponding theoretical description is given accounting for the dipole-dipole
interaction between the two atoms in the presence of a magnetic field and for
polarizations of the quantum field interacting with magnetic sublevels of the
two-atom system. '

text: We study a polar molecule immersed in a superfluid environment, such as a
helium nanodroplet or a Bose–Einstein condensate, in the presence of a strong
electrostatic field. We show that coupling of the molecular pendular motion, induced
by the field, to the fluctuating bath leads to formation of pendulons—spherical
harmonic librators dressed by a field of many-particle excitations. We study the
behavior of the pendulon in a broad range of molecule–bath and molecule–field
interaction strengths, and reveal that its spectrum features a series of instabilities
which are absent in the field-free case of the angulon quasiparticle. Furthermore,
we show that an external field allows to fine-tune the positions of these instabilities
in the molecular rotational spectrum. This opens the door to detailed experimental
studies of redistribution of orbital angular momentum in many-particle systems.
