On quantum entanglement, measurement and decoherence in nanosystems

This thesis discusses the interplay between entanglement, measurement and decoherence in quantum nanosystems.

Entanglement in Solid-State Nanostructures

The goal of this thesis is to investigate theoretically the generation and behaviour of multipartite entanglement for solid-state nanosystems, in particular electron spin quantum bits (so-called 'qubits') in quantum dots. A quantum dot is a tiny potential well where a single electron can be trapped. A quantum bit can be implemented in this...
