Fault-Tolerant Control of Linear Quantum Stochastic Systems

Shi Wang, Daoyi Dong

Published Aug 30, 2016• 40 citations
Publisher

Abstract

In quantum engineering, faults may occur in a quantum control system, which will cause the quantum control system unstable or deteriorate other relevant performance of the system. This note presents an estimator-based fault-tolerant control design approach for a class of linear quantum stochastic systems subject to fault signals. In this approach, the fault signals and some commutative components of the quantum system observables are estimated, and a fault-tolerant controller is designed to compensate the effect of the fault signals. Numerical procedures are developed for controller design and an example is presented to demonstrate the proposed design approach.

Fault-Tolerant Coherent $H^\infty$ Control for Linear Quantum Systems

Yanan Liu, Daoyi Dong, Ian R. Petersen +4 more

Robustness and reliability are two key requirements for developing practical quantum control systems. The purpose of this article is to design a coherent feedback controller for a class of linear quantum systems suffering from Markovian jumping faults so that the closed-loop quantum system has both fault tolerance and$H^\infty$disturbance attenuation performance. This article first extends the physical realization conditions from the time-invariant case to the time-varying case for linear stochastic quantum systems. By relating the fault-tolerant$H^\infty$control problem to the dissipation properties and the solutions of Riccati differential equations, an$H^\infty$controller for the quantum system is then designed by solving a set of linear matrix inequalities. In particular, an algorithm is employed to introduce additional quantum inputs and to construct the corresponding input matrices to ensure the physical realizability of the quantum controller. Also, we propose a real application of the developed fault-tolerant control strategy to quantum optical systems. A linear quantum system example from quantum optics, where the amplitude of the pumping field randomly jumps among different values due to the fault processes, can be modeled as a linear Markovian jumping system. It is demonstrated that a quantum$H^\infty$controller can be designed and implemented using some basic optical components to achieve the desired control goal for this class of systems.

Design of a Discrete-Time Fault-Tolerant Quantum Filter and Fault Detector

Qing Zhong Gao, Daoyi Dong, Ian R. Petersen +1 more

This paper solves the problem of discrete-time fault-tolerant quantum filtering for a class of laser-atom open quantum systems subject to the stochastic faults. We show that by using the discrete-time quantum measurements, optimal estimates of both the atomic observables and the classical fault process can be simultaneously determined in terms of recursive quantum stochastic difference equations. A dispersive interaction quantum system example is used to demonstrate the proposed filtering approach.

Fault tolerant filtering and fault detection for quantum systems driven by fields in single photon states

Qing Gao, Daoyi Dong, Ian R. Petersen +1 more

The purpose of this paper is to solve the fault tolerant filtering and fault detection problem for a class of open quantum systems driven by a continuous-mode bosonic input field in single photon states when the systems are subject to stochastic faults. Optimal estimates of both the system observables and the fault process are simultaneously calculated and characterized by a set of coupled recursive quantum stochastic differential equations.

A unified framework for fault tolerant quantum filtering and fault detection

Qing Zhong Gao, Daoyi Dong, Ian R. Petersen

A quantum-classical probability space model is developed for a class of open quantum systems where the system dynamics involve both classical and quantum random variables. This model provides a unified framework for analyzing open quantum systems subject to stochastic faults. A fault tolerant quantum filter and a fault detection equation are simultaneously derived for this class of open quantum systems using a reference probability approach. A two-level open quantum system subject to Poisson-type faults is presented to illustrate the proposed method. These results have the potential for the systematic development of new fault tolerant control theory for quantum systems.
