On the Infeasibility of Entanglement Generation in Gaussian Quantum Systems via Classical Control

Nurdin, Hendra; Petersen, Ian; James, Matthew


This technical note uses a system theoretic approach to show that classical linear time invariant controllers cannot generate steady state entanglement in a bipartite Gaussian quantum system which is initialized in a Gaussian state. The technical note also shows that the use of classical linear controllers cannot generate entanglement in a finite time from a bipartite system initialized in a separable Gaussian state. The approach reveals connections between system theoretic concepts and the...[Show more]
