Non-Markovian dynamics of a nanomechanical resonator measured by a quantum point contact
Po-Wen Chen, Chung-Chin Jian, Hsi-Sheng Goan
We study the dynamics of a nanomechanical resonator (NMR) subject to a measurement by a low transparency quantum point contact (QPC) or tunnel junction in the non-Markovian domain.…
A microwave transducer for a nano mechnical resonator
G. J. Milburn, C. A. Holmes, L. M. Kettle +1
We give a quantum master equation description of the measurement scheme based on a coplanar microwave cavity capacitively coupled to nano mechanical resonator. The system exhibits…
From insulator to quantum Hall liquid at low magnetic fields
Tsai-Yu Huang, C. -T. Liang, Gil-Ho Kim +5
We have performed low-temperature transport measurements on a GaAs two-dimensional electron system at low magnetic fields. Multiple temperature-independent points and accompanying…
Molecular orbital calculations of two-electron states for P donor solid-state spin qubits
L. M. Kettle, Hsi-Sheng Goan, Sean C. Smith
We theoretically study the Hilbert space structure of two neighbouring P donor electrons in silicon-based quantum computer architectures. To use electron spins as qubits, a crucial…
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…
Monte Carlo Method for a Quantum Measurement Process by a Single-Electron Transistor
Hsi-Sheng Goan
We derive the quantum trajectory or stochastic (conditional) master equation for a single superconducting Cooper-pair box (SCB) charge qubit measured by a single-electron transisto…
