摘要：

我们提出了一个计算机模拟模型，这是一个一对一的副本量子擦除实验与光子（P。D. Schwindt { \sl等人}，A 60，4285（1999））。该模型完全基于实验事实，满足爱因斯坦的局部因果关系准则，不需要波动方程解的知识。尽管如此，模拟模型再现了从量子擦除实验的波动力学描述中获得的平均值，证明了有可能对光子的量子擦除实验给出仅粒子的描述。我们证明，虽然可见度可以作为一个衡量的干涉，它不能用来量化的光子的波动特性。经典的类粒子模拟模型使得用来解释光子量子擦除实验结果的波粒二象性概念变得多余。

英文摘要：

We present a computer simulation model that is a one-to-one copy of a quantum eraser experiment with photons (P. D. D. Schwindt {\sl et al.}, Phys. Rev. A 60, 4285 (1999)). The model is solely based on experimental facts, satisfies Einstein's criterion of local causality and does not require knowledge of the solution of a wave equation. Nevertheless, the simulation model reproduces the averages as obtained from the wave mechanical description of the quantum eraser experiment, proving that it is possible to give a particle-only description of quantum eraser experiments with photons. We demonstrate that although the visibility can be used as a measure for the interference, it cannot be used to quantify the wave character of a photon. The classical particle-like simulation model renders the concept of wave-particle duality, used to explain the outcome of the quantum eraser experiment with photons, superfluous.
