Dynamical protection of quantum steering and fidelity dynamics in the double Jaynes-Cummings model
Koushik Mandal, Chitra Rangan, Shohini Ghose
We investigate the dynamics of Einstein-Podolsky-Rosen (EPR) steering in a double Jaynes-Cummings model, where two initially entangled spatially separated two-level atoms in two ca…
Trees, Forests, and Stationary States of Quantum Lindblad Systems
Patrick Rooney, Anthony M. Bloch, Chitra Rangan
In this paper, we study the stationary orbits of quantum Lindblad systems. We show that they can be characterized in terms of trees and forests on a directed graph with edge weight…
Single particle model of a strongly driven, dense, nanoscale quantum ensemble
C. S. DiLoreto, C. Rangan
We study the effects of interatomic interactions on the quantum dynamics of a dense, nanoscale, atomic ensemble driven by a strong electromagnetic field. We use a self-consistent,…
Quantum Dynamics of a Two-level System Near a Gold Nanoparticle
Somayeh M. A. Mirzaee, Chitra Rangan
The ability to prepare desired states without allowing time for the atomic system to spontaneously decay to the ground state is limited by the fact that Hamiltonian controls cannot…
Flag-based Control of Orbit Dynamics in Quantum Lindblad Systems
Patrick Rooney, Anthony M. Bloch, C. Rangan
In this paper, we demonstrate that the dynamics of an -dimensional Lindblad control system can be separated into its inter- and intra-orbit dynamics when there is fast controlla…
Flag-Based Control of Quantum Purity for Systems
Patrick Rooney, Anthony M. Bloch, C. Rangan
This paper investigates the fast Hamiltonian control of density operators by continuously varying the flag as one moves away from the completely mixed state. In general, the…
