Fault tolerant filtering and fault detection for quantum systems driven by fields in single photon states
Qing Gao, Daoyi Dong, Ian R. Petersen, Herschel Rabitz · Journal of Mathematical Physics · 2016
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.
