A Protocol For Cooling and Controlling Composite Systems by Local Interactions
Daniel Klaus Burgarth, Vittorio Giovannetti · arXiv (Cornell University) · 2007
We discuss an explicit protocol which allows one to externally cool and control a composite system by operating on a small subset of it. The scheme permits to transfer arbitrary and unknown quantum states from a memory on the network ("upload access") as well as the inverse ("download access"). In particular it yields a method for cooling the system.
