量子行走的离散事件模拟

Discrete-event simulation of quantum walks

Madita Willsch, Dennis Willsch, Kristel Michielsen, Hans De Raedt

摘要:

我们使用离散事件模拟在数字计算机上研究实验上可实现的量子行走的两种不同的模型。模拟模型符合爱因斯坦定域性,与简单的随机行走一样“现实”,因为粒子遵循明确定义的轨迹,没有粒子-波对偶性和波函数坍缩等概念,并通过因果,逐事件过程再现量子理论结果。我们的量子行走实验的模拟模型在[C. Robens等人,X 5,011003(2015)]再现了该实验的结果。因此,声称实验结果“严格排除(即,证伪)任何基于经典的、定义明确的轨道的量子输运解释都需要修正。

英文摘要:

We use discrete-event simulation on a digital computer to study two different models of experimentally realizable quantum walks. The simulation models comply with Einstein locality, are as "realistic" as the one of the simple random walk in that the particles follow well-defined trajectories, are void of concepts such as particle-wave duality and wave-function collapse, and reproduce the quantum-theoretical results by means of a cause-and-effect, event-by-event process. Our simulation model for the quantum walk experiment presented in [C. Robens et al., Phys. Rev. X 5, 011003 (2015)] reproduces the result of that experiment. Therefore, the claim that the result of the experiment "rigorously excludes (i.e., falsifies) any explanation of quantum transport based on classical, well-defined trajectories" needs to be revised.
