Learning quantum theory requires dedication and a willingness to challenge classical assumptions. Quantum interference, particularly for massive particles, is a pivotal example in this journey. The Schrödinger equation, inspired by de Broglie’s hypothesis, revolutionized our understanding by revealing the wavelike nature of even massive particles. This phenomenon not only deepens our grasp of nature but also fuels innovations in quantum applications, from quantum sensing to quantum computing. Yet many students don't have the opportunity to run experiments that require sophisticated hardware. Not anymore!
