Figure. Concept of new quantum imaging with ultra-thin nonlinear metasurfaces. The metasurface generates spatially entangled photon pairs, with their emission angle tunable via the pump laser ...

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair. Subscribe to our newsletter for the latest sci-tech news ...

Metasurfaces are highly versatile for manipulating the amplitude, phase, or polarization of light. During the last decade, metasurfaces have been proposed for a vast range of applications — from ...
