High data acquisition rates and low-noise detection of ultracold neutral atoms present important challenges for high-precision atom interferometers that exploit the excellent mode quality of Bose-Einstein condensates. Here, we present a high-flux source of Rb-87 Bose-Einstein condensates combined with a number-resolving detection.
For the high-fidelity tomography of many-body quantum states in the spin degree of freedom, it is desirable to select a single mode for a number-resolving detection. We demonstrate the low-noise selection of subsamples with average atom numbers of up to 35 and their subsequent detection via accurate atom counting. The presented techniques offer an exciting path towards the creation and analysis of mesoscopic quantum states with unprecedented fidelities, and their exploitation for fundamental and metrological applications.
