研究了Brown等人（J Phys A 38（5），1119-1131，2005）提出的五比特真纠缠态在任意三比特态的量子信息分裂中的新应用.我们证明了这样一个真正的五比特纠缠态和一个Bell态可以通过Bell态测量和单比特测量来实现任意三比特态的确定性量子信息系统。所提出的协议被证明是安全的，对某些窃听攻击。
A new application of the genuinely entangled five-qubit state introduced by Brown et al. (J Phys A 38(5), 1119-1131, 2005) is investigated for quantum information splitting (QIS) of an arbitrary three-qubit state. We demonstrate that such a genuine five-qubit entangled state and a Bell-state can be used to realize the deterministic QIS of an arbitrary three-qubit state by performing the Bell-state measurements and single qubit measurement. The presented protocol is showed to be secure against certain eavesdropping attacks.
