Quantum energy teleportation in phase space quantum mechanics
Abstract
In this paper, we investigate the Quantum Energy Teleportation protocol within the phase space formulation of quantum mechanics. By employing the Wigner quasi-probability distribution and the star product, we show that the teleported energy is proportional to the amount of entanglement present in the initial ground state. Further, we introduce the Husimi $Q$-function on a Bloch coherent state in order to determine the Wehrl entropy of the system. Finally, the Wherl entropy enable us to compute the consumption of coherence and entanglement throughout the protocol.
