Polariton interferometer

The Polariton Interferometer is a navigation device proposed for military use because of its independence from traditional GPS, which tends to be subject to jamming and accuracy issues.[1] The polartion interferometer only needs to know its starting location, and works by precisely measuring the changes in movement using interference data from 2 dark-state polaritons, stored in a 1-spin atom,[2] and applying those changes to the starting point. While this would be an incredible technology to incorporate for military and space-program use, it has major obstacles, such as specific operating conditions, arising from the quantum nature of the measurement system used herein, as well as the size and cost of the system, which may require new architecture to incorporate it into existing submarines, and other vehicles.[1]
