Squeezed light mutes quantum noise

Oskar Painter spends his time carving silicon blocks into shapes that interact with light in strange ways. The latest of these — what Painter calls “Legos for adults” — squeezes the light from laser beams to push the limits of what they can measure. By eliminating some of the noise caused by quantum effects, researchers can use squeezed light to illuminate movements too small to see with normal light. Painter’s silicon sculpture, built on a microchip, could boost the sensitivity of sensors that use lasers to monitor motion, such as the gyroscopes that keep track of an aircraft’s orientation.
