Macroscopic Superpositions of Phase States with Bose-Einstein Condensates
F. Piazza, L. Pezze', A. Smerzi
Quantum superpositions of macroscopically distinguishable states having distinct phases can be created with a Bose-Einstein condensate trapped in a periodic potential. The experime…
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…
Non-Linear Beam Splitter in Bose-Einstein Condensate Interferometers
L. Pezze', A. Smerzi, G. P. Berman +2
A beam splitter is an important component of an atomic/optical Mach-Zehnder interferometer. Here we study a Bose Einstein Condensate beam splitter, realized with a double well pote…
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…
Sub Shot-Noise Phase Sensitivity with a Bose-Einstein Condensate Mach-Zehnder Interferometer
L. Pezze', L. A. Collins A. Smerzi, G. P. Berman +1
Bose Einstein Condensates, with their coherence properties, have attracted wide interest for their possible application to ultra precise interferometry and ultra weak force sensors…
