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…
Quantum Computing with Spin Qubits Interacting Through Delocalized Excitons: Overcoming Hole Mixing
Brendon W. Lovett, Ahsan Nazir, Ehoud Pazy +3
As a candidate scheme for controllably coupled qubits, we consider two quantum dots, each doped with a single electron. The spin of the electron defines our qubit basis and trion s…
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…
