Quantum-inspired laser system delivers distance measurements with sub-millimeter accuracy

University of Bristol researchers developed a quantum-inspired laser range-finding technique capable of sub-millimeter accuracy, even under intense sunlight conditions. The breakthrough overcomes traditional limitations of laser-based distance measurement, which often fail in bright environments due to solar interference. Field tests were conducted on the university’s iconic buildings, validating the method’s precision in real-world urban settings. Inspired by quantum principles, the system enhances signal detection by filtering background noise, a technique borrowed from quantum optics. This advancement could revolutionize surveying, autonomous navigation, and industrial metrology where high-precision measurements in daylight are critical.
