报告内容简介：

Realization of an efficient quantum interface will enable deterministic quantum state-transfer between atoms and photons for quantum information processing. A tapered optical nanofiber (ONF) based cavity provides a unique fiber-in-line platform for cavity quantum electrodynamics (QED). In order to trap atoms in the vicinity of the ONF, the only scheme demonstrated previously is the two-color guided mode trap. However, the scheme lacks the control over atom number and position. Recently our lab has demonstrated an optical tweezer based side-illumination trapping scheme to trap and efficiently interface individual single atoms to a few millimeter-long ONF cavity. These results may open new possibilities in quantum-state engineering for potential applications in all-fiber quantum networks and quantum information science [Phys. Rev. Lett. 123, 213602 (2019)].
