This post explores the intriguing world of the quantum double-slit experiment, where particles exhibit interference patterns. By simplifying the experiment to focus on one-dimensional scenarios, the author emphasizes that superposition is an OR state, not an AND. The narrative delves into whether particles or wave functions can pass through multiple doors simultaneously, highlighting the conceptual differences between physical space and the space of possibilities. In the realm of 1920s quantum physics, the post asserts that neither particles nor wave functions can traverse two doors at once. This thought-provoking discussion challenges conventional expectations of quantum phenomena, shedding light on the complexities of wave-particle duality.
