Entanglement is a quintessential property of quantum systems, it captures the fact that its state is written in a manner that is non-separable so that a measurement on one part affects the outcome of the other. Non-separability is not unique to quantum mechanics: weather maps are non-separable, and more pertinently, so are certain forms of structured classical light, controversially referred to as "classically entangled". The similarities between physical optics and quantum mechanics have been understood since the birth of quantum theory. It begs the questions: can quantum correlations be observed in classical systems? When do we really need quantum states of light?
In this webinar, hosted by the OSA Quantum Computing and Communication Technical Group, Professor Andrew Forbes of University of the Witwatersrand, Johannesburg, will review this contentious issue using shaped classical light fields as an example and highlight with examples the advantages classical light offers in studying quantum systems, as well as the limitations inherent in this non-quantum approach. Pertinently, Professor Forbes will show how classical light can be used to blur the classical-quantum divide, demonstrating quantum tools applied to the classical world, and classical beams used in quantum processes, for the best of both worlds.
