On Realization of Back-Action-Evading Measurements and Quantum Non-Demolition Variables via Linear Systems Engineering
Zhiyuan Dong, Weichao Liang, Guofeng Zhang
We establish a framework for realizing back-action-evading (BAE) measurements and quantum non-demolition (QND) variables in linear quantum systems. The key condition, a purely imag…

Linear quantum systems: poles, zeros, invertibility and sensitivity
Zhiyuan Dong, Guofeng Zhang, Heung-wing Joseph Lee +1
The non-commutative nature of quantum mechanics imposes fundamental constraints on system dynamics, which, in the linear realm, are manifested through the physical realizability co…
Linear quantum systems: a tutorial
Guofeng Zhang, Zhiyuan Dong
The purpose of this tutorial is to give a brief introduction to linear quantum control systems. The mathematical model of linear quantum control systems is presented first, then so…
On the dynamics of a quantum coherent feedback network of cavity-mediated double quantum dot qubits
Zhiyuan Dong, Wei Cui, Guofeng Zhang
The purpose of this paper is to present a comprehensive study of a coherent feedback network where the main component consists of two distant double quantum dot (DQD) qubits which…
Quantum filtering for a two-level atom driven by two counter-propagating photons
Zhiyuan Dong, Guofeng Zhang, Nina H. Amini
The purpose of this paper is to propose quantum filters for a two-level atom driven by two continuous-mode counter-propagating photons and under continuous measurements. Two scenar…
