Metrology with -symmetric cavities: Enhanced sensitivity near the -phase transition
Zhong-Peng Liu, Jing Zhang, Şahin Kaya Özdemir +7
We propose and analyze a new approach based on parity-time () symmetric microcavities with balanced gain and loss to enhance the performance of cavity-assisted metrol…
Entanglement distribution over quantum code-division-multiple-access networks
Chang-long Zhu, Nan Yang, Yu-xi Liu +2
We present a method for quantum entanglement distribution over a so-called code-division-multiple-access network, in which two pairs of users share the same quantum channel to tran…
Noise suppression of on-chip mechanical resonators by chaotic coherent feedback
Nan Yang, Jing Zhang, Hui Wang +5
We propose a method to decouple the nanomechanical resonator in optomechanical systems from the environmental noise by introducing a chaotic coherent feedback loop. We find that th…
Signal Flows in Non-Markovian Linear Quantum Feedback Networks
Re-Bing Wu, Jing Zhang, Yu-xi Liu +1
Enabled by rapidly developing quantum technologies, it is possible to network quantum systems at a much larger scale in the near future. To deal with non-Markovian dynamics that is…
Nonlinear quantum input-output analysis using Volterra series
Jing Zhang, Yu-xi Liu, Re-Bing Wu +5
Quantum input-output theory plays a very important role for analyzing the dynamics of quantum systems, especially large-scale quantum networks. As an extension of the input-output…
Quantum feedback: theory, experiments, and applications
Jing Zhang, Yu-xi Liu, Re-Bing Wu +2
The control of individual quantum systems is now a reality in a variety of physical settings. Feedback control is an important class of control methods because of its ability to re…
