On the Structure of Quantum Finite-Level Systems: Decoherence-Free Subsystems, Quantum Nondemolition Variables, and Back-Action-Evading Measurements
Jia Gu, Guofeng Zhang, Ian R. Petersen
The purpose of this paper is to conduct a comprehensive structural analysis of quantum finite-level systems in the Heisenberg picture, where the evolution of system observables is…
Model Reduction for Augmented Model of Linear Non-Markovian Quantum Systems
Guangpu Wu, Shibei Xue, Guofeng Zhang +3
An augmented system model provides an effective way to model non-Markovian quantum systems, which is useful in filtering and control for this class of systems. However, since a lar…
Model Reduction for Linear Quantum Systems
G. P. Wu, S. Xue, G. F. Zhang +1
In this paper, an norm-based model reduction method for linear quantum systems is presented, which can obtain a physically realizable model with a reduced order for…
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…
The Quantum Kalman Decomposition: A Gramian Matrix Approach
Guofeng Zhang, Jinghao Li, Zhiyuan Dong +1
The Kalman canonical form for quantum linear systems was derived in \cite{ZGPG18}. The purpose of this paper is to present an alternative derivation by means of a Gramian matrix ap…
