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…
Multi-point Gaussian states, quadratic-exponential cost functionals, and large deviations estimates for linear quantum stochastic systems
Igor G. Vladimirov, Ian R. Petersen, Matthew R. James
This paper is concerned with risk-sensitive performance analysis for linear quantum stochastic systems interacting with external bosonic fields. We consider a cost functional in th…
Physical Realizability Conditions for Mixed Bilinear-Linear Quantum Cascades with Pure Field Coupling
Luis A. Duffaut Espinosa, Z. Miao, I. R. Petersen +2
This paper aims to provide conditions under which a quantum stochastic differential equation can serve as a model for interconnection of a bilinear system evolving on an operator g…
On the preservation of commutation and anticommutation relations of N-level quantum systems
Luis A. Duffaut Espinosa, Z. Miao, I. R. Petersen +2
The goal of this paper is to provide conditions under which a quantum stochastic differential equation (QSDE) preserves the commutation and anticommutation relations of the SU(n) a…
Preservation of Commutation Relations and Physical Realizability of Open Two-Level Quantum Systems
Luis A. Duffaut Espinosa, Zibo Miao, I. R. Petersen +2
Coherent feedback control considers purely quantum controllers in order to overcome disadvantages such as the acquisition of suitable quantum information, quantum error correction,…
A reduced complexity numerical method for optimal gate synthesis
Srinivas Sridharan, Mile Gu, Matthew R. James +1
Although quantum computers have the potential to efficiently solve certain problems considered difficult by known classical approaches, the design of a quantum circuit remains comp…
