论文摘要

我们引入了量子房效应,这是一种非本地现象,显然不需要量子不和谐。如果两部分系统的子系统都处于纯状态,则足够的效果就足够了。这样,量子房效应完全填补了微不足道的相关性和量子不一致之间的空白。但是,我们讨论了为什么情况比这种情况更微妙的原因,表明在称为“量子室游戏”的具体加密设置中,产生量子不和谐的能力实际上对于量子房屋效应起作用是必不可少的。然后,我们建议一个称为“量子脱离”的原则,以根据物理系统所包含的信息所包含的信息来表征一般量子与经典性的不同地方。量子房效应在Spinq Gemini上证明是一种2 Quibit的液态NMR桌面量子计算机。

We introduce the quantum-house effect, a non-local phenomenon which apparently does not require quantum discord to be present. It suffices for the effect if neither subsystem of a bipartite system is in a pure state. This way, the quantum-house effect completely fills the gap between trivial correlations and quantum discord. However, we discuss why the situation is more subtle than that, by showing that in a concrete cryptographic setting called "the quantum-house game", the ability to produce quantum discord is in fact necessary for the quantum-house effect to work. Then, we suggest a principle called "quantum detachment" to characterize where quantumness in general departs from classicality, based on the information a physical system contains about itself. The quantum-house effect is demonstrated on SpinQ Gemini, a 2-qubit liquid-state NMR desktop quantum computer.
