Researchers have built a quantum sensor prototype that cancels laser phase noise, advancing atom interferometry for cosmic ...

For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies. This phenomenon, known as spin relaxation, ...

Light is incredibly useful in daily life. We use light to see objects and determine details about them. Light is similarly valuable in probing the quantum world. It is often critical for both ...

Solid-state lasers require optical pumping; the most efficient method would be to use a narrow-line source at a suitable absorption frequency larger than the laser’s, but as close as possible. The ...
