Engineering quantum entanglement at the nanoscale

Columbia University School of Engineering and Applied Science
Peer-Reviewed Publication

Currently, the most efficient way to create photon pairs requires sending lightwaves through a crystal large enough to see without a microscope. In a paper published today in Nature Photonics, a team led by Columbia Engineering researchers and collaborators, describe a new method for creating these photon pairs that achieves higher performance on a much smaller device using less energy.
