Abstract:

A scheme is proposed for quantum information splitting (QIS) of a product state of an arbitrary single-qubit state with three-qubit GHZ states. In our scheme, we focus on a product state of an arbitrary single-qubit state, and the original state can be reconstructed only if the receivers cooperate with each other, every receiver has the same authority for getting the sender’s secret, and the receivers have the same probability to get the original secret , the probability to gain is obtained as , the probability to gain is obtained as .

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