Circuit QED techniques have been instrumental in manipulating and probing with exquisite
sensitivity the quantum state of superconducting quantum bits coupled to microwave …

Microwave cavities have been widely used to investigate the behavior of closed few-level
systems. Here, we show that they also represent a powerful probe for the dynamics of …

Control over quantum systems is typically achieved by time-dependent electric or magnetic
fields. Alternatively, electronic spins can be controlled by spin-polarized currents. Here, we …

Following recent achievements in quantum-coherent manipulation and detection of
individual atomic spins with the use of spin-polarized scanning tunneling microscope, we …

We analyze a model of a double quantum dot Cooper pair splitter coupled to two
ferromagnetic detectors and demonstrate the possibility of determination of spin correlation …

Stochastic systems feature, in general, both coherent dynamics and incoherent transitions
between different states. We propose a method to identify the coherent part in the full …

We consider the relaxation dynamics of two spins coupled to a common bosonic bath. The
time evolution is simulated by a generalized master equation derived within a real-time …

We study the interplay of spin and charge coherence in a single-level quantum dot. A tunnel
coupling to a superconducting lead induces superconducting correlations in the dot. With full …

Graphene spintronics offers a promising route to achieve low power 2D electronics for next
generation classical and quantum computation. As device length scales are reduced to the …

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) …
