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 by adding classical communication between different partitions of the system, through so-called ‘quantum energy teleportation’ protocols. In this talk, first, I will present how to fully characterize this distinct notion of local passivity by giving necessary and sufficient conditions using optimization techniques from semidefinite programming [1]. Then, I will introduce the minimal theoretical model of energy activation with a fully unitary quantum energy teleportation protocol [2]. Finally, I will present the first experimental observation of the local activation of a strong local passive state on a bipartite quantum system using nuclear magnetic resonance [2]. Refs.
