A quantum sensor: simultaneous precision gravimetry and magnetic gradiometry with a Bose-Einstein condensate

A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A \(5\times 10^6\) atom F=1 spinor condensate of \(^{87}\)Rb is released into free fall for up to \(750\)ms and probed with a Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simu...

Description
Summary:A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A \(5\times 10^6\) atom F=1 spinor condensate of \(^{87}\)Rb is released into free fall for up to \(750\)ms and probed with a Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states, \(\left| m_f=1,0,-1 \right\rangle\), facilitating a simultaneous measurement of the acceleration due to gravity with an asymptotic precision of $2.1\times 10^{-9}$$\Delta\(g/g and the magnetic field gradient to a precision \)8$pT/m.
