Weird quantum effect used for highly precise interferometer
Posted by Paul Battista in categories: particle physics, quantum physics
A team of researchers from France has developed the first three-directional hybrid quantum inertial sensor, which can measure acceleration without using satellite signals. At the heart of this breakthrough device is something called “matter wave interferometry,” which uses two distinct characteristics of quantum mechanics: wave-particle duality and superposition.
In the cloud
The device consists of a cloud of rubidium atoms that are cooled to temperatures nearing absolute zero. The atoms are placed in a vacuum and are in free fall due to gravity.
