A crossed vortex bottle beam trap for single-atom qubits

Quantum Physics 2015-06-03 v3 Atomic Physics

Abstract

We demonstrate trapping and quantum state control of single Cesium atoms in a 532 nm wavelength bottle beam trap. The three dimensional trap is formed by crossing two unit charge vortex beams. Single atoms are loaded with 50% probability directly from a magneto-optical trap. We achieve a trapping lifetime of up to 6 s, and demonstrate fast Rabi oscillations with a coherence time of T243±9msT_2\sim 43 \pm 9\rm ms.
