论文摘要
我们考虑了一种针对非本地量子相关性的玩具模型,其中大自然诉诸于某种形式的隐藏信号(即,在盒子之间的信号传导,但用户无法使用)以生成相关性。我们表明,如果这样的模型也有内存,各方将能够利用隐藏信号并使用它发送消息,从而实现比光线更快的通信。鉴于内存是任何物理系统易于使用的资源,我们的结果添加了反对隐藏信号作为自然非本地行为背后的机制的证据
We consider a toy model for non-local quantum correlations in which nature resorts to some form of hidden signaling (i.e., signaling between boxes but not available to the users) to generate correlations. We show that if such a model also had memory, the parties would be able to exploit the hidden-signaling and use it to send a message, achieving faster-than-light communication. Given that memory is a resource easily available for any physical system, our results add evidence against hidden signaling as the mechanism behind nature's non-local behavior
