In this paper, we show how the GHZ paradox can be used to design a computing device that cannot be physically implemented within the context of classical physics, but nonetheless can be within quantum physics, i.e., in a quantum physics laboratory. This example gives an illustration of the many subtleties involved in the quantum control of distributed quantum systems. We also show how the second elementary symmetric Boolean function can be interpreted as a quantification of the nonlocality and indeterminism involved in the GHZ paradox.

如何构建无法构建的设备。

在本文中，我们展示了GHZ悖论如何用于设计无法在经典物理学的上下文中物理实现的计算设备，但是仍然可以在量子物理学中，即在量子物理学实验室中实现。这个例子说明了分布式量子系统的量子控制中涉及的许多细节。我们还展示了如何将第二个基本对称布尔函数解释为GHZ悖论中涉及的非局部性和不确定性的量化。
