Sensitivity and back-action in charge qubit measurements by a strongly coupled single-electron transistor
Neil P. Oxtoby, H. M. Wiseman, He-Bi Sun
We consider charge-qubit monitoring (continuous-in-time weak measurement) by a single-electron transistor (SET) operating in the sequential-tunneling regime. We show that commonly…
Quantum trajectories for the realistic measurement of a solid-state charge qubit
Neil P. Oxtoby, P. Warszawski, H. M. Wiseman +2
We present a new model for the continuous measurement of a coupled quantum dot charge qubit. We model the effects of a realistic measurement, namely adding noise to, and filtering,…
Modelling of Optical Detection of Spin-Polarized Carrier Injection into Light-Emitting Devices
M. C. de Oliveira, He Bi Sun
We investigate the emission of multimodal polarized light from Light Emitting Devices due to spin-aligned carriers injection. The results are derived through operator Langevin equa…
Continuous quantum measurement of two coupled quantum dots using a point contact: A quantum trajectory approach
Hsi-Sheng Goan, G. J. Milburn, H. M. Wiseman +1
We obtain the finite-temperature unconditional master equation of the density matrix for two coupled quantum dots (CQD) when one dot is subjected to a measurement of its electron o…
Quantum measurement of coherence in coupled quantum dots
H. M. Wiseman, Dian Wahyu Utami, He Bi Sun +4
We describe the conditional and unconditional dynamics of two coupled quantum dots when one dot is subjected to a measurement of its occupation number using a single electron trans…
Single Spin Measurement using Single Electron Transistors to Probe Two Electron Systems
B. E. Kane, N. S. McAlpine, A. S. Dzurak +4
We present a method for measuring single spins embedded in a solid by probing two electron systems with a single electron transistor (SET). Restrictions imposed by the Pauli Princi…
