Quantum lidar could help driverless vehicles spot bright objects


Entangled photons could make better detectors for driverless cars

user965874/Alamy

Driverless cars can use pulses of laser light to sense objects and measure how far away they are, but this can fail when it is very bright out or a lot of light is reflected from nearby vehicles. Swapping out the lasers for particles of quantum light could make it easier for autonomous vehicles to avoid collisions.

Lidar uses laser light to detect objects, similar to how radar uses radio waves. But there are a lot of sources of light on a …
