A simple laser for quantum-like classical light – Phys.org
Tailoring light is much like tailoring cloth, cutting and snipping to turn a bland fabric into one with a desired pattern. In the case of light, the tailoring is…
A simple laser comprising just two standard mirrors was used to create higher-dimensional classically entangled light, a new state of the art, deviating from the prevailing paradigm of two-dimensional Bell states. The approach combines internal generation, in-principle unlimited in what can be created, with external control, allowing user-defined states to be molded. Shown here are examples of two-dimensional Bell (left) and high-dimensional states (right), including the famous GHZ states. Credit:…
