具有共享EPR对的单侧错误QMA--一个简单的证明

One-Sided Error QMA with Shared EPR Pairs -- A Simpler Proof

Attila Pereszlényi

摘要:

我们给出了Kobayashi,Le Gall和Nishimura [arXiv:1210.1290v2]的一个结果的简单证明,该结果表明任何QMA协议都可以转换为单侧错误协议,其中Arthur和Merlin最初共享常数数量的EPR对,然后Merlin将他的证明发送给Arthur。我们的协议是类似的,但比原来的更简单。我们的主要贡献是一个更简单,更直接的分析的合理性属性,使用众所周知的结果在量子信息,如属性的跟踪距离和保真度,和量子de Finetti定理。

英文摘要:

We give a simpler proof of one of the results of Kobayashi, Le Gall, and Nishimura [arXiv:1210.1290v2], which shows that any QMA protocol can be converted to a one-sided error protocol, in which Arthur and Merlin initially share a constant number of EPR pairs and then Merlin sends his proof to Arthur. Our protocol is similar but somewhat simpler than the original. Our main contribution is a simpler and more direct analysis of the soundness property that uses well-known results in quantum information such as properties of the trace distance and the fidelity, and the quantum de Finetti theorem.
