Quantum information splitting of arbitrary two-particle state using two GHZ states

Abstract

Abstract:

A scheme is presented for quantum information splitting of arbitrary two-particle state by using two GHZ states as quantum channel. In this scheme, Alice performs two Bell-state measurements and publishes four classical bits to her two receivers Bob and Charlie. If the two recipients Bob and Charlie collaborate together, they can deterministically reconstruct the quantum information by performing single-qubit measurements and two single-qubit unitary operations. And the unitary operation is explicitly given with the splitting scheme.

Key words: quantum information, quantum information splitting, GHZ state, unitary operation
