Scientists turn light pulses into atomic mirrors to enhance quantum sensors

Quantum sensors use the wave-like behavior of atoms to measure the acceleration and rotation of objects, such as spacecraft, submarines, or even the Earth’s surface, with great precision.

To work properly, they rely on carefully designed mirrors and beam splitters to control the movement of atoms. However, there could be instances when some atoms reflect in unexpected ways due to flaws in the optical setup or stray light.

These unintended reflections can interfere with the measurements of quantum sensors and reduce their accuracy. The study authors used light pulses as high-velocity atomic mirrors to overcome this challenge.
