text: Superconductor/semiconductor hybrid devices have attracted increasing interest
in the past years. Superconducting electronics aims to complement semiconductor
technology, while hybrid architectures are at the forefront of new ideas such
as topological superconductivity and protected qubits. In this work, we engineer
the induced superconductivity in two-dimensional germanium hole gas by varying
the distance between the quantum well and the aluminum. We demonstrate a hard
superconducting gap and realize an electrically and flux tunable superconducting
diode using a superconducting quantum interference device (SQUID). This allows
to tune the current phase relation (CPR), to a regime where single Cooper pair
tunneling is suppressed, creating a sin(2y) CPR. Shapiro experiments complement
this interpretation and the microwave drive allows to create a diode with ≈ 100%
efficiency. The reported results open up the path towards integration of spin
qubit devices, microwave resonators and (protected) superconducting qubits on the
same silicon technology compatible platform.

text: The epitaxial growth of a strained Ge layer, which is a promising candidate
for the channel material of a hole spin qubit, has been demonstrated on 300 mm
Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB)
layers. The assessment of the layer and the interface qualities for a buried strained
Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping
confirmed that the reduction of the growth temperature enables the 2-dimensional
growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless,
dislocations at the top and/or bottom interface of the Ge layer were observed
by means of electron channeling contrast imaging, suggesting the importance of
the careful dislocation assessment. The interface abruptness does not depend on
the selection of the precursor gases, but it is strongly influenced by the growth
temperature which affects the coverage of the surface H-passivation. The mobility
of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010
/cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the
heterostructure thanks to the high Si0.3Ge0.7 SRB quality.

text: A density wave (DW) is a fundamental type of long-range order in quantum matter
tied to self-organization into a crystalline structure. The interplay of DW order
with superfluidity can lead to complex scenarios that pose a great challenge to
theoretical analysis. In the past decades, tunable quantum Fermi gases have served
as model systems for exploring the physics of strongly interacting fermions, including
most notably magnetic ordering1, pairing and superfluidity2, and the crossover
from a Bardeen–Cooper–Schrieffer superfluid to a Bose–Einstein condensate3. Here,
we realize a Fermi gas featuring both strong, tunable contact interactions and
photon-mediated, spatially structured long-range interactions in a transversely
driven high-finesse optical cavity. Above a critical long-range interaction strength,
DW order is stabilized in the system, which we identify via its superradiant light-scattering
properties. We quantitatively measure the variation of the onset of DW order as
the contact interaction is varied across the Bardeen–Cooper–Schrieffer superfluid
and Bose–Einstein condensate crossover, in qualitative agreement with a mean-field
theory. The atomic DW susceptibility varies over an order of magnitude upon tuning
the strength and the sign of the long-range interactions below the self-ordering
threshold, demonstrating independent and simultaneous control over the contact
and long-range interactions. Therefore, our experimental setup provides a fully
tunable and microscopically controllable platform for the experimental study of
the interplay of superfluidity and DW order.

text: Semiconductor-superconductor hybrid systems are the harbour of many intriguing
mesoscopic phenomena. This material combination leads to spatial variations of
the superconducting properties, which gives rise to Andreev bound states (ABSs).
Some of these states might exhibit remarkable properties that render them highly
desirable for topological quantum computing. The most prominent and hunted of
such states are Majorana zero modes (MZMs), quasiparticles equals to their own
quasiparticles that they follow non-abelian statistics. In this thesis, we first
introduce the general framework of such hybrid systems and, then, we unveil a
series of mesoscopic phenomena that we discovered. Firstly, we show tunneling
spectroscopy experiments on full-shell nanowires (NWs) showing that unwanted quantum-dot
states coupled to superconductors (Yu-Shiba-Rusinov states) can mimic MZMs signatures.
Then, we introduce a novel protocol which allowed the integration of tunneling
spectroscopy with Coulomb spectroscopy within the same device. Employing this
approach on both full-shell NWs and partial-shell NWs, we demonstrated that longitudinally
confined states reveal charge transport phenomenology similar to the one expected
for MZMs. These findings shed light on the intricate interplay between superconductivity
and quantum confinement, which brought us to explore another material platform,
i.e. a two-dimensional Germanium hole gas. After developing a robust way to induce
superconductivity in such system, we showed how to engineer the proximity effect
and we revealed a superconducting hard gap. Finally, we created a superconducting
radio frequency driven ideal diode and a generator of non-sinusoidal current-phase
relations. Our results open the path for the exploration of protected superconducting
qubits and more complex hybrid devices in planar Germanium, like Kitaev chains
and hybrid qubit devices.

text: The spin-orbit interaction permits to control the state of a spin qubit via
electric fields. For holes it is particularly strong, allowing for fast all electrical
qubit manipulation, and yet an in-depth understanding of this interaction in hole
systems is missing. Here we investigate, experimentally and theoretically, the
effect of the cubic Rashba spin-orbit interaction on the mixing of the spin states
by studying singlet-triplet oscillations in a planar Ge hole double quantum dot.
Landau-Zener sweeps at different magnetic field directions allow us to disentangle
the effects of the spin-orbit induced spin-flip term from those caused by strongly
site-dependent and anisotropic quantum dot g tensors. Our work, therefore, provides
new insights into the hole spin-orbit interaction, necessary for optimizing future
qubit experiments.

text: Hybrid semiconductor–superconductor devices hold great promise for realizing
topological quantum computing with Majorana zero modes1,2,3,4,5. However, multiple
claims of Majorana detection, based on either tunnelling6,7,8,9,10 or Coulomb
blockade (CB) spectroscopy11,12, remain disputed. Here we devise an experimental
protocol that allows us to perform both types of measurement on the same hybrid
island by adjusting its charging energy via tunable junctions to the normal leads.
This method reduces ambiguities of Majorana detections by checking the consistency
between CB spectroscopy and zero-bias peaks in non-blockaded transport. Specifically,
we observe junction-dependent, even–odd modulated, single-electron CB peaks in
InAs/Al hybrid nanowires without concomitant low-bias peaks in tunnelling spectroscopy.
We provide a theoretical interpretation of the experimental observations in terms
of low-energy, longitudinally confined island states rather than overlapping Majorana
modes. Our results highlight the importance of combined measurements on the same
device for the identification of topological Majorana zero modes.

abstract:
- lang: eng
text: A semiconducting nanowire fully wrapped by a superconducting shell has been
proposed as a platform for obtaining Majorana modes at small magnetic fields.
In this study, we demonstrate that the appearance of subgap states in such structures
is actually governed by the junction region in tunneling spectroscopy measurements
and not the full-shell nanowire itself. Short tunneling regions never show subgap
states, whereas longer junctions always do. This can be understood in terms of
quantum dots forming in the junction and hosting Andreev levels in the Yu-Shiba-Rusinov
regime. The intricate magnetic field dependence of the Andreev levels, through
both the Zeeman and Little-Parks effects, may result in robust zero-bias peaks—features
that could be easily misinterpreted as originating from Majorana zero modes but
are unrelated to topological superconductivity.

text: Hole gases in planar germanium can have high mobilities in combination with
strong spin-orbit interaction and electrically tunable g factors, and are therefore
emerging as a promising platform for creating hybrid superconductor-semiconductor
devices. A key challenge towards hybrid Ge-based quantum technologies is the design
of high-quality interfaces and superconducting contacts that are robust against
magnetic fields. In this work, by combining the assets of aluminum, which provides
good contact to the Ge, and niobium, which has a significant superconducting gap,
we demonstrate highly transparent low-disordered JoFETs with relatively large
ICRN products that are capable of withstanding high magnetic fields. We furthermore
demonstrate the ability of phase-biasing individual JoFETs, opening up an avenue
to explore topological superconductivity in planar Ge. The persistence of superconductivity
in the reported hybrid devices beyond 1.8 T paves the way towards integrating
spin qubits and proximity-induced superconductivity on the same chip.

text: "In the worldwide endeavor for disruptive quantum technologies, germanium
is emerging as a versatile material to realize devices capable of encoding, processing,
or transmitting quantum information. These devices leverage special properties
of the germanium valence-band states, commonly known as holes, such as their inherently
strong spin-orbit coupling and the ability to host superconducting pairing correlations.
In this Review, we initially introduce the physics of holes in low-dimensional
germanium structures with key insights from a theoretical perspective. We then
examine the material science progress underpinning germanium-based planar heterostructures
and nanowires. We review the most significant experimental results demonstrating
key building blocks for quantum technology, such as an electrically driven universal
quantum gate set with spin qubits in quantum dots and superconductor-semiconductor
devices for hybrid quantum systems. We conclude by identifying the most promising
prospects\r\ntoward scalable quantum information processing. "

text: 'Quantum information and computation has become a vast field paved with opportunities
for researchers and investors. As large multinational companies and international
funds are heavily investing in quantum technologies it is still a question which
platform is best suited for the task of realizing a scalable quantum processor.
In this work we investigate hole spins in Ge quantum wells. These hold great promise
as they possess several favorable properties: a small effective mass, a strong
spin-orbit coupling, long relaxation time and an inherent immunity to hyperfine
noise. All these characteristics helped Ge hole spin qubits to evolve from a single
qubit to a fully entangled four qubit processor in only 3 years. Here, we investigated
a qubit approach leveraging the large out-of-plane g-factors of heavy hole states
in Ge quantum dots. We found this qubit to be reproducibly operable at extremely
low magnetic field and at large speeds while maintaining coherence. This was possible
because large differences of g-factors in adjacent dots can be achieved in the
out-of-plane direction. In the in-plane direction the small g-factors, on the
other hand, can be altered very effectively by the confinement potentials. Here,
we found that this can even lead to a sign change of the g-factors. The resulting
g-factor difference alters the dynamics of the system drastically and produces
effects typically attributed to a spin-orbit induced spin-flip term. The investigations
carried out in this thesis give further insights into the possibilities of holes
in Ge and reveal new physical properties that need to be considered when designing
future spin qubit experiments.'

text: Spin qubits are considered to be among the most promising candidates for building
a quantum processor. Group IV hole spin qubits have moved into the focus of interest
due to the ease of operation and compatibility with Si technology. In addition,
Ge offers the option for monolithic superconductor-semiconductor integration.
Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical
field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge
and by encoding the qubit into the singlet-triplet states of a double quantum
dot. We observe electrically controlled X and Z-rotations with tunable frequencies
exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with
echo techniques. These results show that Ge hole singlet triplet qubits outperform
their electronic Si and GaAs based counterparts in speed and coherence, respectively.
In addition, they are on par with Ge single spin qubits, but can be operated at
much lower fields underlining their potential for on chip integration with superconducting
technologies.

text: The potential of Si and SiGe-based devices for the scaling of quantum circuits
is tainted by device variability. Each device needs to be tuned to operation conditions.
We give a key step towards tackling this variability with an algorithm that, without
modification, is capable of tuning a 4-gate Si FinFET, a 5-gate GeSi nanowire
and a 7-gate SiGe heterostructure double quantum dot device from scratch. We achieve
tuning times of 30, 10, and 92 minutes, respectively. The algorithm also provides
insight into the parameter space landscape for each of these devices. These results
show that overarching solutions for the tuning of quantum devices are enabled
by machine learning.

text: "Quantum computation enables the execution of algorithms that have exponential
complexity. This might open the path towards the synthesis of new materials or
medical drugs, optimization of transport or financial strategies etc., intractable
on even the fastest classical computers. A quantum computer consists of interconnected
two level quantum systems, called qubits, that satisfy DiVincezo’s criteria. Worldwide,
there are ongoing efforts to find the qubit architecture which will unite quantum
error correction compatible single and two qubit fidelities, long distance qubit
to qubit coupling and \r\n calability. Superconducting qubits have gone the furthest
in this race, demonstrating an algorithm running on 53 coupled qubits, but still
the fidelities are not even close to those required for realizing a single logical
qubit. emiconductor qubits offer extremely good characteristics, but they are
currently investigated across different platforms. Uniting those good characteristics
into a single platform might be a big step towards the quantum computer realization.\r\nHere
we describe the implementation of a hole spin qubit hosted in a Ge hut wire double
quantum dot. The high and tunable spin-orbit coupling together with a heavy hole
state character is expected to allow fast spin manipulation and long coherence
times. Furthermore large lever arms, for hut wire devices, should allow good coupling
to superconducting resonators enabling efficient long distance spin to spin coupling
and a sensitive gate reflectometry spin readout. The developed cryogenic setup
(printed circuit board sample holders, filtering, high-frequency wiring) enabled
us to perform low temperature spin dynamics experiments. Indeed, we measured the
fastest single spin qubit Rabi frequencies reported so far, reaching 140 MHz,
while the dephasing times of 130 ns oppose the long decoherence predictions. In
order to further investigate this, a double quantum dot gate was connected directly
to a lumped element\r\nresonator which enabled gate reflectometry readout. The
vanishing inter-dot transition signal, for increasing external magnetic field,
revealed the spin nature of the measured quantity."
