It is unanimously accredited that the quantum and the classical descriptions of the actual truth are very diversified, even though any quantum method is "mysteriously" reworked via dimension into an observable classical occasion. past the conceptual modifications, quantum and classical physics have much in universal. And, extra vital, there are classical and quantum phenomena which are comparable even though they ensue in different contexts. for instance, the Schrödinger equation has an analogous mathematical shape because the Helmholtz equation, there's an uncertainty relation in optics similar to that during quantum mechanics, etc; the record of examples is particularly lengthy. Quantum-classical analogies were utilized in fresh years to review many quantum legislation or phenomena on the macroscopic scale, to layout and simulate mesoscopic units on the macroscopic scale, to enforce quantum machine algorithms with classical capability, and so forth. nonetheless, the hot varieties of gentle – localized mild, frozen gentle – appear to have extra in universal with good kingdom physics than with classical optics. So those analogies are a worthy instrument within the quest to appreciate quantum phenomena and within the look for new (quantum or classical) functions, in particular within the zone of quantum units and computing.
