Quantum decoherence explains wavefunction collapse through environmental interaction

Quantum decoherence describes the transition of a quantum system from a coherent state to a state that aligns with classical mechanics. This process involves the loss of quantum coherence as a system interacts with its environment, leading to the apparent collapse of the wavefunction.

Example

Consider an electron in a superposition of states. When it interacts with the surrounding environment, such as air molecules or electromagnetic fields, it loses its coherent superposition and appears to collapse into a definite state.

Remember this

Understanding decoherence is crucial for developing practical quantum technologies, such as quantum computing, which rely on maintaining quantum coherence.
