Quantum state-agnostic work extraction (almost) without dissipation
Josep Lumbreras, Ruo Cheng Huang, Yanglin Hu +2
We investigate work extraction protocols designed to transfer the maximum possible energy to a battery using sequential access to copies of an unknown pure qubit state. The cor…

Some properties and applications of the new quantum -divergences
Salman Beigi, Christoph Hirche, Marco Tomamichel
Recently, a new definition for quantum -divergences was introduced based on an integral representation. These divergences have shown remarkable properties, for example when inve…
