Dynamics and Control of Open Quantum Systems

Control and Optimization of Open Quantum Systems for Information Processing

This workshop was held at the American Institute of Mathematics (AIM) in Palo Alto, CA from June 21-25, 2010. The workshop enabled researchers from three distinct quantuminformation-science research communities to interact and exchange ideas. Specifically, these fields were dynamical decoupling (Lie-algebra based), optimal control (topology/variationalcalculus based) and quantum error-correctio...

A pseudospectral method for optimal control of open quantum systems.

In this paper, we present a unified computational method based on pseudospectral approximations for the design of optimal pulse sequences in open quantum systems. The proposed method transforms the problem of optimal pulse design, which is formulated as a continuous-time optimal control problem, to a finite-dimensional constrained nonlinear programming problem. This resulting optimization probl...

Control of Open Quantum Systems by Nicolas Boulant

This thesis describes the development, investigation and experimental implementation via liquid state nuclear magnetic resonance techniques of new methods for controlling open quantum systems. First, methods that improve coherent control through the use of both strong control fields and detailed knowledge of the subsystem's Hamiltonian are demonstrated. With the aid of numerical search methods,...
