Canonical Quantum Teleportation
arXiv:quant-ph/0001052 · doi:10.1103/PhysRevA.61.022310
Abstract
Canonically conjugated observables such as position-momentum and phase-number are found to play a 3-fold role in the drama of the quantum teleportation. Firstly, the common eigenstate of two commuting canonical observables like phase-difference and number-sum provides the quantum channel between two systems. Secondly, a similar pair of canonical observables from another two systems is measured in the Bell operator measurements.
