Phys. Rev. A 62, 032101 (2000) [4 pages]Bell theorem for the nonclassical part of the quantum teleportation processReceived 8 December 1999; published 3 August 2000 The quantum teleportation process is composed of a joint measurement performed upon two uncorrelated subsystems A and B, followed by a unitary transformation (parameters of which depend on the outcome of the measurement) performed upon a third subsystem C (EPR correlated with system B). The information about the outcome of the measurement is transferred by classical means. It is shown that this measurement process, plus possible measurements on subsystem C (with the classical channel switched off), cannot be described by a local realistic theory. © 2000 The American Physical Society URL:
