Abstract

The phenomenon of interference lies at the heart of quantum physics, and is responsible for many of the unusual aspects of quantum behaviour that deviate from our everyday expectations. Though classical physics allows for waves (e.g. of sound) to interfere, quantum theory allows for interference effects also to affect single particles. One device that demonstrates this experimentally is the Mach–Zehnder interferometer: here a single particle (e.g. a photon) travels down one of two possible paths, and quantum interference between the two paths affects the final position where the particle arrives. In this article, I propose a mechanism to musically demonstrate quantum single-particle interference: the musical Mach–Zehnder interferometer. This new quantum musical instrument makes use of two independently operated electronic keyboards, whose outputs are interfered according to the rules of the Mach–Zehnder interferometer. I discuss the musical possibilities this instrument enables, and outline a method to construct it via software simulation.
音乐马赫-曾德尔干涉仪
干涉现象是量子物理学的核心,也是量子行为中许多不同寻常的方面偏离我们日常预期的原因。尽管经典物理学允许波(例如声音)干涉,量子理论允许干涉效应也影响单个粒子。马赫-曾德干涉仪是一种实验证明这一点的设备:在这里,单个粒子(例如光子)沿着两条可能的路径之一运动,两条路径之间的量子干涉会影响粒子到达的最终位置。在这篇文章中,我提出了一种用音乐来演示量子单粒子干涉的机制:音乐马赫-曾德尔干涉仪。这种新的量子乐器使用两个独立操作的电子键盘,其输出根据马赫-曾德尔干涉仪的规则进行干扰。我讨论了这种乐器的音乐可能性,并概述了一种通过软件模拟来构建它的方法。
