一种提取多部CSS状态的散列协议

Hashing protocol for distilling multipartite CSS states

Erik Hostens, Jeroen Dehaene, Bart De Moor

摘要:

我们提出了一个散列协议,通过本地Clifford操作,泡利测量和经典的通信来提取多部CSS状态。它表明,该散列协议优于以前的版本,充分利用信息论,不仅适用于本地Clifford操作的hocTs。使用信息理论的概念,一个强典型集,我们计算的协议作为一个线性规划问题的解决方案的渐近收益率。

英文摘要:

We present a hashing protocol for distilling multipartite CSS states by means of local Clifford operations, Pauli measurements and classical communication. It is shown that this hashing protocol outperforms previous versions by exploiting information theory to a full extent an not only applying CNOTs as local Clifford operations. Using the information-theoretical notion of a strongly typical set, we calculate the asymptotic yield of the protocol as the solution of a linear programming problem.
