Quantum Sensors: A Revolution in the Offing?

New measuring devices exploit the extreme sensitivity of quantum states—but making them practical is a challenge.

by Edwin Cartlidge

Single-Photon Sources

Exploring and extending the promise of quantum technologies requires the ability to work with single quantum objects—especially photons. Here’s a look at the range of single-photon-source technologies available, and how and where they work.
