Optimal Control of a Markovian Qubit with Unitary Control
Emanuel Malvetti
We study a single Markovian qubit governed by a Lindblad master equation and subject to fast unitary control. Using reduced control systems and optimal control theory we determine…

Provably Time-Optimal Cooling of Markovian Quantum Systems
Emanuel Malvetti
We address the problem of cooling a Markovian quantum system to a pure state in the shortest amount of time possible. Here the system drift takes the form of a Lindblad master equa…

Entanglement in Bipartite Quantum Systems with Fast Local Unitary Control
Emanuel Malvetti
The well-known Schmidt decomposition, or equivalently, the complex singular value decomposition, states that a pure quantum state of a bipartite system can always be brought into a…
