Optimal control at the quantum speed limit
T Caneva et al. Phys Rev Lett. 2009.
Abstract
Optimal control theory is a promising candidate for a drastic improvement of the performance of quantum information tasks. We explore its ultimate limit in paradigmatic cases, and demonstrate that it coincides with the maximum speed limit allowed by quantum evolution.
