= Dephasing
{wiki=Dephasing}
Dephasing is a concept primarily encountered in quantum mechanics and quantum information theory, as well as in classical wave physics. It refers to the process in which a coherent quantum state loses its relative phase information due to interactions with the environment or other systems. In quantum mechanics, particles such as electrons and photons can exist in superposition states, meaning they can simultaneously occupy multiple states. Coherence is crucial for maintaining these superpositions.
