Activation of Strong Local Passive States with Quantum Energy Teleportation Protocols
ORAL
Abstract
Strong local passivity is a property of multipartite systems from which it is impossible to locally extract energy. Surprisingly, if the system in a strong local passive state displays entanglement, it could be possible to locally activate energy density by adding classical communication between different partitions of the system, through so-called ‘quantum energy teleportation’ protocols. In this talk, I will present both the minimal theoretical model of activation with a fully unitary quantum energy teleportation protocol and the first experimental realization of local activation on a bipartite quantum system using nuclear magnetic resonance.
