Quantum logical networks for probabilistic teleportation of many particle state of general form

Abstract

The scheme for probabilistic teleportation of an $N$-particle state of general form is proposed. As the special cases we construct efficient quantum logic networks for implementing probabilistic teleportation of a two-particle state, a three-particle state and a four-particle state of general form, built from single qubit gates, two-qubit controlled-not gates, Von Neumann measurement and classically controlled operations.

An efficient scheme for generalized tripartite controlled teleportation of a two-quNit entangled state

“…By virtue of a shared resource of entanglement and some classical information, Bennett et al [1] first proposed the quantum teleportation scheme, where the sender can transmit an unknown qubit to a distant receiver via a quantum channel (EPR pairs) with two-bit classical communication. Up to now, quantum teleportation has always received much attention both theoretically [2][3][4][5][6][7][8][9][10][11][12][13] and experimentally [14][15][16] due to its important applications in quantum communication processing and quantum computation.…”

Quantum Logic Networks for Probabilistic and Controlled Teleportation of Unknown Quantum States

“…[25,26] In terms of only single-qubit gates, two-qubit CNOT gates, Von Neumann measurement, and classically controlled operations, Gao et al constructed an efficient quantum logic networks for probabilistic teleportation of an unknown two-particle state, three-particle state, and four-particle state in a general form. [27,28] Clearly the quantum logic networks for probabilistically teleporting an unknown state will be important in realizing the teleportation scheme in the experiment.…”
