Abstract
A tripartite quantum operation sharing protocol is proposed by utilizing a five-qubit absolutely maximally entangled (AME) state presented by Helwig et al. (Phys. Rev. A 86, 052335 (2012). The security of the proposed protocol is analyzed and ensured. The essential role of the state in this quantum task is explained. The protocol determinacy and the sharer asymmetry are identified. The experimental feasibility of the proposed protocol is discussed and confirmed. Moreover, the protocol is compared with Peng’s tripartite protocol using a six-qubit AME state [Quantum Inf Process 14, 4255 (2015)] and its distinct advantages of consuming less quantum resources, degrading the intensity of necessary operations, and owning the higher intrinsic efficiency, are revealed.
