Quantum teleportation by entanglement swapping with trapped ions

An effective teleportation scheme for an unknown ionic internal statevia trapped ions is proposed without joint Bell-state measurement(BSM). In the constructed quantum channel process, we make use ofentanglement swapping to avoid decrease in entanglement duringthe distributing of particles. Thus our scheme provides new prospectsfor quantum teleportation in a longer distance. The distinctadvantage of our scheme is insensitive to the heating of vibrationalmode. Furthermore, our scheme has no any individual optical access,and the successful probability also can reach 1.
