General optical state truncation and its teleportation
Mátyás Koniorczyk, Z. Kurucz, A. Gábris, József Janszky · Physical Review A · 2000
A setup is proposed in which the number-state expansion of a one-mode traveling-wave optical field is truncated so as to leave its vacuum, one-, and two-photon components. The process is a realization of quantum teleportation on a three-state basis. The possibility of generalization to the first n components is also considered.
