Abstract:
A controlled quantum dense coding scheme is proposed with a three-particle non-maximally entangled Greenberger-Horne-Zeilinger (GHZ) state. The third party controlls the quantum channel via the local measurement. By introducing an auxiliary particle and performing an unitary transformation, quantum dense coding will be succeeded with certain probability.[著者文摘]
