Attraction Domain Analysis for Steady States of Markovian Open Quantum Systems
Shikun Zhang, Guofeng Zhang
This article concerns the attraction domain analysis for steady states in Markovian open quantum systems. The central question is proposed as: given a steady state, which part of t…
Quantum coherent and measurement feedback control based on atoms coupled with a semi-infinite waveguide
Haijin Ding, Nina H. Amini, Guofeng Zhang +1
In this paper, we show that quantum feedback control may be applied to generate desired states for atomic and photonic systems based on a semi-infinite waveguide coupled with multi…
Quantum coherent feedback control of an N-level atom with multiple excitations
Haijin Ding, Guofeng Zhang
The purpose of this paper is to study the dynamics of a quantum coherent feedback network, where an -level atom is coupled with a cavity and the cavity is also coupled with sing…
Quantum feedback control of a two-atom network closed by a semi-infinite waveguide
Haijin Ding, Guofeng Zhang, Mu-Tian Cheng +1
The purpose of this paper is to study the delay-dependent coherent feedback dynamics by focusing on one typical realization, i.e., a two-atom quantum network whose feedback loop is…
Efficient Depth Selection for the Implementation of Noisy Quantum Approximate Optimization Algorithm
Yu Pan, Yifan Tong, Shibei Xue +1
Noise on near-term quantum devices will inevitably limit the performance of Quantum Approximate Optimization Algorithm (QAOA). One significant consequence is that the performance o…
Quantum coherent feedback control with photons
Haijin Ding, Guofeng Zhang
The purpose of this paper is to study two-photon dynamics induced by the coherent feedback control of a cavity quantum electrodynamics (cavity-QED) system coupled to a waveguide. I…
