Phase measurements exhibiting super sensitivity and super resolution features
Clemens Schäfermeier, Miroslav Ježek, Tobias Gehring, Ulrik L. Andersen · Conference on Lasers and Electro-Optics · 2016
By using an optical squeezed state and a post-processed homodyne detection scheme we show that phase measurements can overcome Rayleigh’s resolution criterion and beat the quantum shot noise limit simultaneously.
