Atom interferometers are examples of quantum sensors, which rely on the strange phenomena that emerge at the universe’s tiniest scales.

Researchers have developed a new laser system to help make these sensors fit in a shoebox, as well as potentially mass-producible.

The laser system may also help reduce costs of hundreds of modulators.

The researchers integrated their new modulators into an atom interferometer.

The scientists detailed their findings on 10 July in the journal Science Advances .

“The final performance of this accelerometer doesn’t yet compete with the best laboratory quantum inertial sensor out there,” Kodigala says.
