Design of Coherent Passive Quantum Equalizers Using Robust Control Theory
V. Ugrinovskii, M. R. James
The paper develops a methodology for the design of coherent equalizing filters for quantum communication channels. Given a linear quantum system model of a quantum communication ch…
Coherent Equalization of Linear Quantum Systems
V. Ugrinovskii, M. R. James
This paper introduces a -like methodology of coherent filtering for equalization of passive linear quantum systems to help mitigate degrading effects of quantum communica…
Quadratic-exponential functionals of Gaussian quantum processes
Igor G. Vladimirov, Ian R. Petersen, Matthew R. James
This paper is concerned with exponential moments of integral-of-quadratic functions of quantum processes with canonical commutation relations of position-momentum type. Such quadra…
Measurement-based feedback control of linear quantum stochastic systems with quadratic-exponential criteria
Igor G. Vladimirov, Matthew R. James, Ian R. Petersen
This paper is concerned with a risk-sensitive optimal control problem for a feedback connection of a quantum plant with a measurement-based classical controller. The plant is a mul…
Frequency-domain computation of quadratic-exponential cost functionals for linear quantum stochastic systems
Igor G. Vladimirov, Ian R. Petersen, Matthew R. James
This paper is concerned with quadratic-exponential functionals (QEFs) as risk-sensitive performance criteria for linear quantum stochastic systems driven by multichannel bosonic fi…
A Girsanov type representation of quadratic-exponential cost functionals for linear quantum stochastic systems
Igor G. Vladimirov, Ian R. Petersen, Matthew R. James
This paper is concerned with multimode open quantum harmonic oscillators and quadratic-exponential functionals (QEFs) as quantum risk-sensitive performance criteria. Such systems a…
