Explaining Quanta with Optical Illusions (2501.08583v1)

Abstract: In this work, I propose a way to help high school students and the general population understand quantum concepts by adopting a new inherently dual representation. Major difficulties in explaining to people the basic concepts of quantum mechanics reside in the apparent impossibility of representing quantum superposition with examples taken from everyday life. In this context, I propose a new pictorial paradigm that illustrates a number of quantum concepts by means of optical illusions, potentially without raising misconceptions. The method is based on "bistable reversible figures", which induce in the viewer a multistable perception, conveying a direct understanding of superposition, random collapse, and observer effect via a sensorial experience. I present the advantages and discuss the limitations of this analogy, and show how it extends to the concepts of complementarity and quantum entanglement, also helping to avoiding misconceptions in quantum teleportation. Finally, I also address quantum spin and quantum measurement by using different types of optical illusions.
