decoherence
/ˌdiːkoʊˈhɪərəns/
Definition
The process by which a quantum system loses its sensitive wave-like properties due to interaction with the surrounding environment, effectively destroying quantum information.
Etymology
The word is derived from the prefix 'de-' (meaning reversal or removal) and the Latin 'cohaerere' (to stick together or hold fast). It emerged in physics to describe the 'un-sticking' or breakdown of coherent quantum states.
In the news
In the article, decoherence is described as a noise-related phenomenon that disrupts the quantum states of molecules, which the researchers aim to minimize in their precision measurement experiments.
