The physical meaning of phase and its importance for quantum
teleportation
S. J. van Enk
abstract: We argue that the two parties in a quantum teleportation protocol need to
share more resources than just an entangled state and a classical communication
channel. As the phase between orthogonal states has no physical meaning by
itself, a shared standard defining all relevant phases is necessary. We discuss
several physical implementations of qubits and the corresponding physical
meaning of phase.
