"Quantum energy teleportation for a tripartite spin chain system in a Gibbs State"
Jose Daniel Trevison Solano (Tohoku University)
We considered quantum energy teleportation protocols in three element Ising spin chain system coupled to a thermal bath. In particular, a closed chain, and a open chain with non periodic boundary conditions were analyzed. For temperatures lower than a strong-passivity critical temperature the protocol becomes effective. On the other hand, for temperatures above the critical temperature it was found an optimal protocol which allows the amount of teleported energy to be larger than extractable energy by arbitrary local operations.
