Continuous measurement of a microwave-driven solid state qubit
S. D. Barrett, T. M. Stace
We analyze the dynamics of a continuously observed, damped, microwave driven solid state charge qubit. The qubit consists of a single electron in a double well potential, coupled t…
Two spin measurements in exchange interaction quantum computers
S. D. Barrett, T. M. Stace
We propose and analyse a method for single shot measurement of the total spin of a two electron system in a coupled quantum dot or donor impurity structure, which can be used for r…
Parity measurement of one- and two-electron double well systems
T. M. Stace, S. D. Barrett, H. -S. Goan +1
We outline a scheme to accomplish measurements of a solid state double well system (DWS) with both one and two electrons in non-localised bases. We show that, for a single particle…
Selective spin coupling through a single exciton
A. Nazir, B. W. Lovett, S. D. Barrett +2
We present a novel scheme for performing a conditional phase gate between two spin qubits in adjacent semiconductor quantum dots through delocalized single exciton states, formed t…
