Cooling a charged mechanical resonator with time-dependent bias gate voltages
Jian-Qi Zhang, Yong Li, Mang Feng
We show a purely electronic cooling scheme to cool a charged mechanical resonator (MR) down to nearly the vibrational ground state by elaborately tuning bias gate voltages on the e…
Exact Non-Markovian Master Equation and Dispersive Probing of Non-Markovian Process
Li-Ping Yang, C. Y. Cai, D. Z. Xu +2
For a bosonic (fermionic) open system in a bath with many bosons (fermions) modes, we derive the exact non-Markovian master equation in which the memory effect of the bath is refle…
Precision measurement of charge number with optomechanically induced transparency
Jian-Qi Zhang, Yong Li, Mang Feng +1
We propose a potentially practical scheme to precisely measure the charge numbers of small charged objects by optomechanical systems using optomechanically induced transparency (OM…
Confidence and Backaction in the Quantum Filter Equation
Wei Cui, Neill Lambert, Yukihiro Ota +4
We study the confidence and backaction of state reconstruction based on a continuous weak measurement and the quantum filter equation. As a physical example we use the traditional…
Global Quantum discord of multi-qubit states
Jianwei Xu
Global quantum discord (GQD), proposed by Rulli and Sarandy [Phys. Rev. A \textbf{84}, 042109 (2011)], is a generalization of quantum discord to multipartite states. In this paper,…
Franck-Condon Effect in Central Spin System
Li-Ping Yang, Yong Li, C. P. Sun
We study the quantum transitions of a central spin surrounded by a collective-spin environment. It is found that the influence of the environmental spins on the absorption spectrum…
