Time-minimum control of quantum purity for 2-level Lindblad equations
William Clark, Anthony Bloch, Leonardo Colombo +1
We study time-minimum optimal control for a class of quantum two-dimensional dissipative systems whose dynamics are governed by the Lindblad equation and where control inputs acts…
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…
Optimal Control of Quantum Purity for Systems
William Clark, Anthony Bloch, Leonardo Colombo +1
The objective of this work is to study time-minimum and energy-minimum global optimal control for dissipative open quantum systems whose dynamics is governed by the Lindblad equati…
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…
Decoherence Control and Purification of Two-dimensional Quantum Density Matrices under Lindblad Dissipation
Patrick Rooney, Anthony Bloch, Chitra Rangan
Control of quantum dissipative systems can be challenging because control variables are typically part of the system Hamiltonian, which can only generate motion along unitary orbit…
