Many emerging quantum technologies demand precise engineering and control over
networks consisting of quantum mechanical degrees of freedom connected by propagating …

The purpose of this tutorial is to give a brief introduction to linear quantum control systems.
The mathematical model of linear quantum control systems is presented first, then some …

The control of flying quantum bits (qubits) carried by traveling quantum fields is crucial for
coherent information transmission in quantum networks. In this paper, we develop a general …

The control of flying qubits is at the core of quantum networks. When the flying qubits are
carried by single-photon fields, the control involves not only their logical states but also their …

We derive quantum trajectories (also known as stochastic master equations) that describe
an arbitrary quantum system probed by a propagating wave packet of light prepared in a …

We derived quantum trajectories for a system interacting with the environment prepared in a
continuous mode single-photon state as the limit of a discrete filtering model with an …

The purpose of this paper is to propose quantum filters for a two-level atom driven by two
continuous-mode counter-propagating photons and under continuous measurements. Two …

An approximate exponential quantum projection filtering scheme is developed for a class of
open quantum systems described by Hudson–Parthasarathy quantum stochastic differential …

This work extends the previous quantum projection filtering scheme in Gao et al.(2019), by
adding an optimality analysis result. A reformulation of the quantum projection filter is …

In this paper, we investigate the dynamics of quantum linear systems where the input signals
are multi-channel multi-photon states, namely states determined by a definite number of …
