Phys. Rev. A 65, 012320 (2001) [6 pages]From classical state swapping to quantum teleportationReceived 29 May 2001; published 14 December 2001 The quantum teleportation protocol is extracted directly out of a standard classical circuit that exchanges the states of two qubits using only controlled-NOT gates. This construction of teleportation from a classically transparent circuit generalizes straightforwardly to d-state systems. © 2001 The American Physical Society URL:
