Avoiding entanglement sudden-death via measurement feedback control in a quantum network
Naoki Yamamoto, Hendra I. Nurdin, Matthew R. James +1
In this paper, we consider a linear quantum network composed of two distantly separated cavities that are connected via a one-way optical field. When one of the cavity is damped an…
Quantum Feedback Networks: Hamiltonian Formulation
J. Gough, M. R. James
A quantum network is an open system consisting of several component Markovian input-output subsystems interconnected by boson field channels carrying quantum stochastic signals. Ge…
Coherent quantum LQG control
H. I. Nurdin, M. R. James, I. R. Petersen
Based on a recently developed notion of physical realizability for quantum linear stochastic systems, we formulate a quantum LQG optimal control problem for quantum linear stochast…
Quantum Dissipative Systems and Feedback Control Design by Interconnection
Matthew R. James, John Gough
The purpose of this paper is to extend J.C. Willems' theory of dissipative systems to the quantum domain. This general theory, which combines perspectives from the quantum physics…
The Series Product and Its Application to Quantum Feedforward and Feedback Networks
J. Gough, M. R. James
The purpose of this paper is to present simple and general algebraic methods for describing series connections in quantum networks. These methods build on and generalize existing m…
A discrete invitation to quantum filtering and feedback control
Luc Bouten, Ramon van Handel, Matthew R. James
The engineering and control of devices at the quantum-mechanical level--such as those consisting of small numbers of atoms and photons--is a delicate business. The fundamental unce…
