Quantum Energy Teleportation under Equilibrium and Nonequilibrium Environments
Xiaokun Yan, Kun Zhang, Jin Wang
Quantum energy teleportation (QET), implemented via local operations and classical communication, enables carrier-free energy transfer by exploiting quantum resources. While QET ha…

Fluctuation theorems for multipartite quantum coherence and correlation dynamics
Kun Zhang, Mo-Yang Ni, Hai-Long Shi +2
Fluctuation theorems establish exact relations for nonequilibrium dynamics, profoundly advancing the field of stochastic thermodynamics. In this work, we extend quantum fluctuation…

Quasiprobability fluctuation theorem behind the spread of quantum information
Kun Zhang, Jin Wang
Information spreads in time. For example, correlations dissipate when the correlated system locally couples to a third party, such as the environment. This simple but important fac…
