To provide a quantization communication method and its system by which teleportation of quantization bits is realized.
A 1st particle [1] having a quantum condition in response to information to be transmitted, and 2nd and 3rd particles [2], [3] correlated with each other including a tangled state in terms of quantum mechanics are prepared. The 1st particle [1] and the 2nd particle [2] are possessed by a sender and the 3rd particle [3] is possessed by a receiver. The sender and the receiver have in common a state 16 of mixing a quantum condition obtained by a synthesis system of the 2nd and 3rd particles [2], [3] and a quantum condition obtained by a product state between the quantum condition of the 1st particle [1] and its orthogonal state at a prescribed ratio. The measurement result conducted by the sender in the system consisting of the 1st and 2nd particles [1], [2] is sent to the receiver through a classic communication path, and the receiver reproduces the quantum condition lost from the 1st particle [1] by the 3rd particle [3] by measuring the 3rd particle [3] based on the information sent through the classic communication path.
