Quantum Dots for Quantum Information Processing: Controlling and Exploiting the Quantum Dot Environment

This thesis offers a comprehensive introduction to surface acoustic waves in the quantum regime. It addresses two of the most significant technological challenges in developing a scalable quantum information processor based on spins in quantum dots: (i) decoherence of the electronic spin qubit due to the surrounding nuclear spin bath, and (ii) long-range spin-spin coupling between remote qubits.

Electron spins confined in quantum dots (QDs) are among the leading contenders for implementin...
