The viewpoint by a University of Bristol academic on a recent experiment, which shows that exotic quantum processes are not necessary to reach the ultimate limits of measurements, is reported in the international journal Science.

Dr Jeremy O’Brien, Reader in Research at the Centre for Quantum Photonics in the Department of Physics and the Department of Electrical & Electronic Engineering, said: “All science is founded on measurement and improvements in precision have led not just to more detailed knowledge but also to new fundamental understanding.”
