Decoherence and Measurement of Charge Qubits in Double Quantum Dots
Decoherence and Measurement of Charge Qubits in Double Quantum Dots
In this thesis, theoretical studies of decoherence properties and the measurement process of a charge qubit defined in a double quantum dot structure are summarized. There have been three experimental realizations of charge qubits in double quantum dots already, where the quality factors have been quite small. Therefore, the theoretical analysis of possible decoherence mechanisms and how measurements can ideally be performed could be beneficial for the further development in new experiments.

Abstract

In this thesis, theoretical studies of decoherence properties and the measurement process of a charge qubit defined in a double quantum dot structure are summarized. There have been three experimental realizations of charge qubits in double quantum dots already, where the quality factors have been quite small. Therefore, the theoretical analysis of possible decoherence mechanisms and how measurements can ideally be performed could be beneficial for the further development in new experiments.
