摘要

量子信息分裂或量子态共享是经典秘密共享方案在量子方案中的概括。在量子信息分裂中，一种量子态的形式被划分并分发给多个接收者。提出一个通过使用六粒子的最大纠缠态作为量子通道来分裂两量子比特混态的方案。首先Alice执行两个Bell基测量并且宣布测量结果，同时分配Charlie(Bob)来重建未知的初态。如果控制者 Bob(Charlie)同意帮助Charlie(Bob)获得初态，他们就在各自的量子比特上执行单粒子测量。在发送者对粒子执行Bell基测量以及合作者对粒子执行单粒子测量之后，通过运用适当的幺正算符，接收者可以重建发送者信息的初始状态。

Abstract

Quantum information splitting (QIS) or quantum state sharing is the generalization of classical secret sharing schemes to the quantum scenario. In QIS, a piece of quantum information (in the form of a quantum state) is divided and distributed to a number of receivers. A scheme of splitting two-qubit states was proposed by using six-particle maximally entangled state as the quantum channel. Alice first performs two Bell-basis measurement and announces her measurement outcome and assigns Charlie (Bob) to reconstruct the original unknown state. If the controllers Bob (Charlie) agree to help Charlie (Bob) obtain the original state, they should perform single-particle measurements on their respective qubits. After the sender performs Bell-basis measurements on her particles, and the cooperators operate single-particle measurements on their particles, the state receiver can reconstruct the original state of the sender by applying the appropriate unitary operation.
