Entanglement-free, Heisenberg-limited Phase Measurement

Not Accessible

Your library or personal account may give you access


We demonstrate experimental Heisenberg-limited scaling of the variance in optical phase measurements. Our algorithm replaces entangled states - often thought essential for Heisenberg scaling - with single photons, multiple phase shift passes, and adaptive measurement.
