Quantum Metrology with Cold AtoMS

Abstract

As quantum metrology advanced, it has achieved better sensitivity scaling in estimation of various parameters of different quantum mechanical systems. Interferometry is the most suitable method to perform measurements and implement the parameter estimation theories. We obtain interesting results when we merge the field of ultra-cold matter and quantum metrology. Here, numerical simulations of using a two-mode Bose Einstein condensate for performing Ramsay interferometry is presented. It is observed to attain the sensitivity scaling better than Heisenberg limit.
