Enhanced quantum teleportation using multi-qubit logical states

Abstract

In this paper, an innovative approach is suggested for quantum teleportation of multi-qubit physical state into an error correctable multi-qubit logical state. For this purpose, an efficient quantum error correction scheme is applied to detect and correct one bit flip and/or phase flip error in the teleported logical state. In addition, the proposed mechanism is substantiated by teleporting an eight-qubit physical state via four-qubit cluster state which involves three-qubit logical states as a quantum channel. The proposed scheme may be physically realized in the future fault tolerant quantum technologies.
