Teleportation of n-Particle State via n Pairs of EPR Channels

The teleportation of an arbitrary n-particle state $(n \ge 1)$ is proposed if n pairs of identical EPR states are utilized as quantum channels. Independent Bell state measurements are performed for joint measurement. By using a special Latin square of order $2^n(n \ge 1)$, explicit expressions of outcomes after the Bell state measurements by Alice (sender) and the corresponding unitary transformations by Bob (receiver) can be derived. It is shown that the teleportation of n-particle state can be implemented by a series of single-qubit teleportation.
