Population inversion of driven two-level systems in a structureless bath
T. M. Stace, A. C. Doherty, S. D. Barrett
We derive a master equation for a driven double-dot damped by an unstructured phonon bath, and calculate the spectral density. We find that bath mediated photon absorption is impor…
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…
Continuous measurement of a charge qubit with a point contact detector at arbitrary bias: the role of inelastic tunnelling
T. M. Stace, S. D. Barrett
We study the dynamics of a charge qubit, consisting of a single electron in a double well potential, coupled to a point-contact (PC) electrometer using the quantum trajectories for…
