How does the quantum measurement work as a projection?
In the realm of quantum mechanics, the measurement process plays a fundamental role in determining the state of a quantum system. When a quantum system is in a superposition of states, meaning it exists in multiple states simultaneously, the act of measurement collapses the superposition into one of its possible outcomes. This collapse is often
