Entanglement, Non-linear Dynamics, and the Heisenberg Limit
L. Pezze', A. Smerzi
We show that the quantum Fisher information provides a sufficient condition to recognize multi-particle entanglement in a qubit state. The same criterion gives a necessary and…

Mach-Zehnder Interferometry at the Heisenberg Limit with coherent and squeezed-vacuum light
L. Pezze', A. Smerzi
We show that the phase sensitivity of a Mach-Zehnder interferometer fed by a coherent state in one input port and squeezed-vacuum in the other one is i) independent from the t…

Phase detection at the quantum limit with multi-photon Mach-Zehnder interferometry
L. Pezze, A. Smerzi, G. Khoury +2
We study a Mach-Zehnder interferometer fed by a coherent state in one input port and vacuum in the other. We explore a Bayesian phase estimation strategy to demonstrate that it is…
