Generating entangled photons with nonlinear metasurfaces

Illustration of a metasurface generating pairs of photons (shown as spheres).  The photon entanglement can be varied by changing the pump beam (shown in red). Illustration by Andrei Komar & Matthew Parry. Subhed: A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions—an important step towards creating miniaturized […]
