Quantum Positioning System

Posted 22 Aug 2001 at 22:30 UTC by steve Share This

Seth Lloyd and other MIT researchers have announced a paper detailing what they call a Quantum Positioning System (QPS). They plan to exploit quantum weirdness to increase the accuracy of traditional pulse-timing methods used by most current positioning systems such as GPS, sonar, lidar, and radar. They claim their scheme could increase the precision of such systems by a factor of 1000 or more. (a related scheme using quantum entanglement to syncronize clocks was proposed last year by Isaac Chuang of IBM.)
