Description
Summary:In recently, we have proposed a scheme to sensitive quantum measurement using ultracold atoms [1]. Most attractive properties of the system, its measurement sensitivity limit is very high due to the quantum nature of the ultracold atoms. Here, we propose a temperature sensitivity measurement of the order of Pico-Kelvin and an another sensitive measurement of purity gas of bosons in phase-space. The impurity in the gases changes the effective mass of the system; this combined mass is the reduced mass. This mass difference will result in relative phase difference which we measured in Wigner phase-space. In this scheme we showed a measurement when mass difference is 2.4 % of actual mass.
