Quantum Measurements

Quantum measurements involve observing particles like electrons or photons, which exist in a state of possibilities called superposition. Before measurement, they have multiple potential outcomes simultaneously. When a measurement is made, this superposition "collapses" into a specific state, determining a single outcome. This process is fundamental to quantum mechanics and differs from classical measurements because it directly influences the system being observed. In essence, quantum measurement is the act that turns probabilities into actual, observable results, revealing the particle’s state at the moment of measurement.
