Abstract

An atom interferometer using a Bose–Einstein condensate of 87Rb atoms is utilized for the measurement of magnetic-field gradients. Composite optical pulses are used to construct a spatially symmetric Mach–Zehnder geometry. By using a biased interferometer we demonstrate the ability to measure small residual forces in our system and discriminate between magnetic and inertial effects. These are a residual ambient magnetic-field gradient of 15±2 mG/cm and an inertial acceleration of 0.08±0.02 m/s2. Our method has important applications in the calibration of precision measurement devices and the reduction of systematic errors.
