Tuning entanglement with an asymmetric metasurface

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned, from a layer thinner than a human hair. The photon pairs are created by a metasurface made of indium gallium phosphide (InGaP), which has a nonlinear response that can split a classical photon into two quantum photons. By tuning the wavelength of the initial photon, the two new photons can be generated as fully entangled...
