Many of the new generation of quantum technologies rely on the precise control of light. Quantum information is carried by photons, and lasers are used to manipulate matter in quantum computers, sensors, cameras, clocks and cryptography. This has become possible through the ability to generate and work with very pure light, with precise frequencies and low phase noise, thanks to advanced laser systems. The field is now being driven in two directions – towards higher power with low noise to enable full‐scale quantum computers, and towards miniature, low cost systems for commercial clocks and sensors.
