Multiqubit Quantum Teleportation

TL;DR

This paper introduces a new class of six-qubit states for perfect three-qubit teleportation, generalizes them to 2n-qubit states for n-qubit teleportation, and discusses their application in dense coding.

Contribution

It presents a novel class of multi-qubit states for quantum teleportation and extends this to a general framework for n-qubit teleportation and dense coding.

Findings

Includes six-qubit states for perfect three-qubit teleportation.

Generalizes to 2n-qubit states for n-qubit teleportation.

Applicable for dense coding of 2n classical bits.

Abstract

We provide a class of six-qubit states for three-qubit perfect teleportation. These states include the six-qubit cluster states as a special class. We generalize this class of six-qubit states to 2n-qubit pure states for n-qubit teleportation, n >=1. These states can be also used for 2n bit classical information transmission in dense coding.
