‘Tipping point’ between quantum and classical worlds identified

24 marzo 2015

If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons — the fundamental unit of light. Achieving such understanding, however, is easier said than done. That’s because the physical behavior of photons — similar to electrons and other sub-atomic particles — is characterized not by classical physics, but by quantum mechanics. Now, scientists have observed the point at which classical and quantum behavior converge.
