To build novel quantum devices, researchers need to be able to control individual photons of light: Engineers propose doing so with a time lens. Like a magnifying glass zooming in on a spatial feature, this device ‘magnifies’ time and enabled the team to identify single photons from a larger laser beam at picosecond resolution — that’s 70x faster than has been observed with other types of single-photon detectors.
