摘要

无信号集大于量子集的事实表明，可以通过调用额外的约束来切断多余的区域。在本章中，我们提出了一些作为“物理原理”的约束:信息因果性、宏观局部性和局部正交性。这三种方法都捕捉到了量子集的有趣特征，但都不能准确地把它挑出来。

The Quest for Device-Independent Quantum Principles

The fact that the no-signaling set is larger than the quantum set suggests that the excess regions could be cut off by invoking additional constraints. In this chapter, we present some of the constraints that have been proposed as “physical principles”: information causality, macroscopic locality and local orthogonality. All three capture interesting features of the quantum set but fail to single ti out exactly.
