In this thesis, we investigate carbon nanotube (CNT) quantum dot (QD) hybrid devices-in
which a single CNT is coupled either to superconducting (S) and normal metal (N) …

A key element in quantum computing applications is the ability to measure non-local
correlations, known as entanglement, as well as reliably generate them. A naturally …

In this thesis, we investigate integrated quantum dots as tunnel spectrometers in
semiconductor–superconductor nanowire hybrid devices, by means of low temperature …

This thesis aims to study InAs nanowires with built-in crystal-phase defined quantum dots as
a platform for quantum computing. We investigate them as a platform for topological qubits …

Fast measurement of small currents and even smaller fluctuations in devices with large
impedance is not trivial. Standard low frequency lock-in measurements suffer from stray …

Quantum entanglement has applications in quantum cryptography and quantum computing
as the main and speed-enhancing ingredient to quantum algorithms. A possible way to …

Noise is defined as random fluctuations of a signal in time. The fundamental requirement for
noise is some sort of randomness. Noise is well-known and infamous to every …

The implementation of ferromagnetic contacts in complex nanoelectronic devices, eg in spin-
valves bears great potential for applications and fundamental investigations. Spin-valves are …

Semiconducting nanowires have attracted a large research interest in the recent years due
to their flexibility to fabricate various quantum electronic devices. The semicondcuting nature …

This thesis presents results from experimental and theoretical investigations of carbon
nanotube (CNT) quantum devices at cryogenic temperatures. Specifically, Cooper pair …
