How can interference be a quantum system
Web21 de out. de 2024 · Interference isn’t just a wave phenomenon. The most general thing it means is this: when you have a linear system, the sum of two solutions is also a solution. But often quantities we care about are quadratic, not linear (the wave energy for electromagnetic waves; the probability for quantum states).
