Atomic interferometry with ultra-low noise quantum sensors
Atom interferometers utilize the wavelike behavior of atoms to make extremely precise measurements of gravity, acceleration, and rotation. These sensors are able to achieve sensitivities and accuracies superior to traditional light-based interferometers by making better use of the unique properties of quantum mechanics. The contemporaneous utilizing of optical lattices and laser beams in the new layout makes it possible to manage atoms on a scale that can measure just a few micrometres extensive, seamlessly down to nanometre-degree rotational sensing. The move marks a huge step towards Quantum technology being used in practical applications, from navigation systems to research in fundamental physics. This is an area with vast potential for further research and development, leading to new scientific avenues and opportunities for technological advance.
