Quantum Measurement

Quantum measurement refers to the process of observing or detecting a property of a quantum system, like an electron or photon. Before measurement, such systems exist in a superposition—a combination of multiple possible states. When measured, the superposition collapses into a single, definite state, revealing a specific outcome. This process is fundamental to quantum mechanics and differs from classical measurement because it directly influences the state of the system. Essentially, measurement turns a range of possibilities into a concrete result, highlighting the intricate and probabilistic nature of quantum phenomena.
