Physicists at the University of Colorado Boulder have created a groundbreaking quantum device that can measure 3D acceleration using ultracold atoms.

By chilling rubidium atoms to near absolute zero and splitting them into quantum superpositions, the team has built a compact atom interferometer guided by AI to decode acceleration patterns.

NASA awarded the researchers a $5.5 million grant through the agency's Quantum Pathways Institute to continue developing the sensor technology.

The Bose-Einstein Condensate is a matter-wave pond made of atoms.

When the atoms snap back together, they form a unique pattern, just like the two beams of laser light zipping together.

"We can decode that fingerprint and extract the acceleration that the atoms experienced," Holland said.
