幻态蒸馏协议的结构

On the Structure of Protocols for Magic State Distillation

Earl T. Campbell, Dan E. Browne

摘要:

我们提出了一个定理,表明所有有用的协议的魔术状态蒸馏输出状态的保真度是上限的一类协议所产生的。这个简化的类由协议组成,其中状态的多个副本被投射到稳定器码空间上,然后逻辑量子比特被解码。

英文摘要:

We present a theorem that shows that all useful protocols for magic state distillation output states with a fidelity that is upper-bounded by those generated by a much smaller class of protocols. This reduced class consists of the protocols where multiple copies of a state are projected onto a stabilizer codespace and the logical qubit is then decoded.
