Classical vs. Quantum Light Fields

Isaac Nape

Analogies between quantum entanglement and nonseparable classical structured-light fields are yielding new insights and potential applications.

Recent advances are breaking the barriers between classical and quantum light. [I. Nape]

Over the past century, advances in classical and quantum optics have shaped developments in telecommunications, sensing, manufacturing, medical imaging and many other areas. Driving these advances has been the sophisticated control of lasers and individual photon states, facilitated by the development of tools that manipulate individual degrees of freedom of light such as time, frequency, spatial, path and polarization.
