Abstract

We investigate a game where a sender (Alice) teleports coherent states to two receivers (Bob and Charlie) through a tripartite Gaussian state. The aim of the receivers is to optimize their teleportation fidelities by means of local operations and classical communications. We show that a non-cooperative strategy corresponding to the standard telecloning protocol can be outperformed by a cooperative strategy which gives rise to a novel (cooperative) telecloning protocol.
