GPS-free navigation nears reality with quantum technology breakthrough | Integrated photonic chips enable compact, low-cost quantum navigation
The idea of using quantum technology for navigation isn't exactly novel. The technique relies on sensors called atom interferometers that can track position and motion without any...
In a nutshell: Today's typical navigation-grade motion sensors are about the size of a grapefruit, helping steer ships, planes, and vehicles in conjunction with GPS signals. A team at Sandia National Labs has developed ultra-compact optical chips that can power those quantum navigation sensors in a package small enough to stick basically anywhere. "By harnessing the principles of quantum mechanics, these advanced sensors provide unparalleled accuracy in measuring acceleration and angular velocity, enabling precise navigation even in GPS-denied areas," said Sandia scientist Jongmin Lee.
