Collective purification of interacting quantum networks beyond symmetry constraints
Saikat Sur, Pritam Chattopadhyay, Arnab Chakrabarti +5
Following any quantum information processing protocol, it is essential to reset a mixed state of a many-body interacting spin-network to the computational-zero pure state. This tas…

Power enhancement of heat engines via correlated thermalization in multilevel systems
David Gelbwaser-Klimovsky, Wolfgang Niedenzu, Paul Brumer +1
We analyze a heat machine based on a periodically-driven quantum system permanently coupled to hot and cold baths. It is shown that the maximal power output of a degenerate -typ…
