量子信息有多少种分裂方式?
In how many ways can quantum information be split ?
摘要:
我们建立了一个理论上的理解,介导的量子信息分裂协议的物理系统的纠缠特性。我们量化了不同的方式,其中任意的$n$量子比特状态可以分裂之间的一组$k$参与者使用$N$量子比特纠缠信道,使得原始信息可以完全重建,只有当所有的参与者合作。基于此量化,我们展示了如何设计一个量子协议,以最少的资源和定义的分裂效率的量子信道,它提供了一种方法来表征纠缠态的基础上,他们的有用性,这样的量子网络协议。
英文摘要:
We establish a theoretical understanding of the entanglement properties of a physical system that mediates a quantum information splitting protocol. We quantify the different ways in which an arbitrary $n$ qubit state can be split among a set of $k$ participants using a $N$ qubit entangled channel, such that the original information can be completely reconstructed only if all the participants cooperate. Based on this quantification, we show how to design a quantum protocol with minimal resources and define the splitting efficiency of a quantum channel which provides a way of characterizing entangled states based on their usefulness for such quantum networking protocols.
