projection postulate
The projection postulate is a fundamental concept in quantum mechanics. It states that the act of measuring an observable on a quantum system causes the system to collapse into one of the eigenstates of that observable. This collapse is known as wavefunction collapse and is represented mathematically by the projection operator. The projection postulate helps us understand how quantum systems transition from a superposition of states to a definite state upon measurement. It forms the basis for the probabilistic nature of quantum measurements and is essential in describing the behavior of quantum particles.
