Quantum control and signal enhancement exploiting the Stokes-anti-Stokes coherence
Wen-Zhao Zhang, Keye Zhang, Jie Li
We present a theoretical framework for the coherent coupling between Stokes and anti-Stokes scattering processes, revealing interference phenomena inaccessible to either process al…
Quantum Zeno effect in self-sustaining systems: suppressing phase diffusion via repeated measurements
Wenlin Li, Najmeh Es'haqi-Sani, Wen-Zhao Zhang +1
We study the effect of frequent projective measurements on the dynamics of quantum self-sustaining systems, by considering the prototypical example of the quantum Van der Pol oscil…
Measurement of the mechanical reservoir spectral density in optomechanical system
Wen-Zhao Zhang, Xian-Ting Liang, Jiong Cheng +1
To investigate the dynamical behavior of a quantum system embedded in a memory environment, it is crucial to obtain the knowledge of the reservoir spectral density. However, such k…
Quantum correlation enhanced weak field detection in optomechanical system
Wen-Zhao Zhang, Li-Bo Chen, Jiong Cheng +1
We propose a theoretical scheme to enhance the signal-to-noise ratio in ultrasensitive detection with the help of quantum correlation. By introducing the auxiliary oscillator and t…
Bistable cooling in optomechanical system
Wen-Zhao Zhang, Wen-Lin Li, Jiong Cheng +1
A scheme is presented to optimize the optomechanical cooling of mechanical resonator in instability regime. Based on the stability analysis, we uncovered a distinct bistable effect…
Optomechanical cooling in the non-Markovian regime
Wen-Zhao Zhang, Jiong Cheng, Wen-Dong Li +1
We propose a scheme in which the cooling of a mechanical resonator is achieved by exposing the optomechanical system to a non-Markovian environment. Because of the backflow from th…
