System for Trapping Cold Neutral Atoms Around an Optical Nanofiber

POSTER

Abstract

We have constructed a robust system for studying atom-light interactions in atomtronics and hybrid quantum information. We require the loading of atomic dipole traps formed on tapered optical nanofibers and other photonic structures from magneto-optical traps. A commercially available UHV manipulator allows for controlled translation of the structures into the chamber with the trap while reducing the turn-around time to obtain ultra-high vacuum. The translation and pump out protocols require care not to destroy or contaminate the fibers and other photonic structures. We can, for example, translate a 500 nm diameter, 2 cm length optical nanofiber to the center of a $^{87}$Rb cloud and load cold atoms into the evanescent field around the nanofiber. We also present experimental proposals to use the nanofiber trap as a microwave-to-optical photon transducer and as part of a stable atomic memory in a hybrid quantum processor that combines atoms and circuit-QED.
