Entanglement swapping with local certification: Application to remote micromechanical resonators

Entanglement swapping allows to entangle two distant systems which never interacted. This paper applies this protocol to an initial tripartite systems of two identical cavity optomechanical systems. Each system is formed by a micro-mechanical resonator playing the role of the remote mode, coupled to two independently driven optical cavity modes with different frequencies, whose output field are sent to Bell and certification modes.
