Structural characterization of linear quantum systems with application to back-action evading measurement
Guofeng Zhang, Ian R. Petersen, Jinghao Li
The purpose of this paper is to study the structure of quantum linear systems in terms of their Kalman canonical form, which was proposed in a recent paper \cite{ZGPG18}. The spect…
On the dynamics of two photons interacting with a two-qubit coherent feedback network}
Guofeng Zhang, Yu Pan
The purpose of this paper is to study the dynamics of a quantum coherent feedback network composed of two two-level systems (qubits) driven by two counter-propagating photons, one…
Single-photon quantum filtering with multiple measurements
Zhiyuan Dong, Guofeng Zhang, Nina H. Amini
The single-photon quantum filtering problems have been investigated recently with applications in quantum computing. In practice, the detector responds with a quantum efficiency of…
On the response of a two-level system to two-photon inputs
Zhiyuan Dong, Guofeng Zhang, Nina H. Amini
The purpose of this paper is to study the interaction between a two-level system and two continuous-mode photons. Two scenarios are investigated: Case 1, how a two-level system cha…
