Quantum teleportation and state sharing using a genuinely entangled six-qubit state
Abstract
The usefulness of the genuinely entangled six-qubit state that has recently been introduced by Borras et al (2007 J. Phys. A: Math. Theor. 40 13407) is investigated for the quantum teleportation of an arbitrary three-qubit state and for quantum state sharing (QSTS) of an arbitrary two-qubit state. We construct two distinct protocols for QSTS of an arbitrary two-qubit state using this state as an entangled channel. We construct 16 orthogonal four-qubit states which can lock an arbitrary two-qubit state between two parties.
