Multiparty teleportation
Wolfgang Dür, J. I. Cirac · Journal of Modern Optics · 2000
We consider the problem of multiparty teleportation, where N copies of a qubit are teleported to N different locations. We show how to achieve this by measuring an appropriate POVM and using the multiparticle entangled state introduced in the context of telecloning. Our procedure also gives the optimal N ← M telecloning.
