Two-step feedback preparation of entanglement for qubit systems with time delay
Yanan Liu, Daoyi Dong, Sen Kuang +2
Quantum entanglement plays a fundamental role in quantum computation and quantum communication. Feedback control has been widely used in stochastic quantum systems to generate give…
Fault-tolerant control for optical parametric oscillators with pumping fluctuations
Yanan Liu, Daoyi Dong, Ian R. Petersen +1
Optical Parametric Oscillators (OPOs) have wide applications in quantum optics for generating squeezed states and developing advanced technologies. When the phase or/and the amplit…
A Coherent LQG approach to Quantum Equalization
Rebbecca TY Thien, Shanon L. Vuglar, Ian R. Petersen
We propose a method to design a suboptimal, coherent quantum LQG controller to solve a quantum equalization problem. Our method involves reformulating the problem as a control prob…
Coherent quantum LQG controllers with Luenberger dynamics
Igor G. Vladimirov, Ian R. Petersen
This paper is concerned with the coherent quantum linear-quadratic-Gaussian control problem of minimising an infinite-horizon mean square cost for a measurement-free field-mediated…
Measuring decoherence by commutation relations decay for quasilinear quantum stochastic systems
Igor G. Vladimirov, Ian R. Petersen
This paper considers a class of open quantum systems with an algebraic structure of dynamic variables, including the Pauli matrices for finite-level systems as a particular case. T…
A J-spectral Factorization Condition for the Physical Realizability of a Transfer Function Matrix with only Direct Feedthrough Quantum Noise
Rebbecca TY Thien, Shanon L. Vuglar, Ian R. Petersen
This paper gives a J-spectral factorization condition for the implementation of a strictly proper transfer function matrix as a physically realizable quantum system using only dire…
