论文摘要
大型现实主义是许多但不是全部经典系统的特征。例如，众所周知，经典的光可能违反leggett-garg的不平等，因此拒绝了大型现实主义的解释。最近的一个实验使用了纠缠的轻和负测量结果来证明无漏洞的大分子测试[PRX量子$ \ Mathbf {3} $，010307（2022）]。本文表明，这种实验虽然非常拒绝大分，但仍可以接受经典的解释。这是通过在带有梁阻滞剂的光学干涉仪中提供明确的征兆光子检测的明确经典模型来完成的。该模型的数值分析表明，与实验观察和与当地现实主义和对大分现实主义的拒绝的一致性相吻合。
Macrorealism is a characteristic feature of many, but not all, classical systems. It is known, for example, that classical light can violate a Leggett-Garg inequality and, hence, reject a macrorealist interpretation. A recent experiment has used entangled light and negative measurements to demonstrate a loophole-free test of macrorealism [PRX Quantum $\mathbf{3}$, 010307 (2022)]. This paper shows that such an experiment, while soundly rejecting macrorealism, may nevertheless be open to a classical interpretation. This is done by offering an explicit classical model of heralded photon detection in an optical interferometer with beam blockers. A numerical analysis of the model shows good agreement with experimental observations and consistency with both local realism and a rejection of macrorealism.
