Staying adiabatic with unknown energy gap
J. Nehrkorn, S. Montangero, A. Ekert +3
We introduce an algorithm to perform an optimal adiabatic evolution that operates without an apriori knowledge of the system spectrum. By probing the system gap locally, the algori…
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…
Phase Sensitivity of a Mach-Zehnder Interferometer
Luca Pezze', Augusto Smerzi
The best performance of a Mach-Zehnder interferometer is achieved with the input state |N_T/2 + 1>|N_T/2-1 > + |N_T/2 - 1>|N_T/2+1>, being N_T the total number of atoms/photons. Th…
