一类三量子比特 X 态的几何量子失协

Abstract

Abstract:

Based on the definition of multipartite quantum discord proposed in [Phys Rev Lett, 124, 110401(2020)], we give the analytic expression for the multipartite geometric quantum discord of one type of three-qubit X states which depend on four real parameters by measurement induction. And we present the level surfaces of the class of three-qubit X states. As an application, we investigate the dynamic behavior of multipartite geometric quantum discord for the three-qubit X states under the phase flip channel.

Key words: Geometric quantum discord, Three-qubit X states, Phase flip channel
