Heisenberg-scaling measurement of the single-photon Kerr non-linearity using mixed states
Improving the precision of measurements is a significant scientific challenge. Previous works suggest that in a photon-coupling scenario the quantum fisher information shows a quantum-enhanced scaling of N(2), which in theory allows a better-than-classical scaling in practical measurements. In this...
