Trapping and optically interfacing laser-cooled neutral atoms are essential requirements for their use in advanced quantum technologies. Here we simultaneously realize both of these tasks with cesium atoms interacting with a multicolor evanescent field surrounding an optical nanofiber. The atoms are localized in a one-dimensional optical lattice about 200 nm above the nanofiber surface and can be efficiently interrogated with a resonant light field sent through the nanofiber. Our technique opens the route towards the direct integration of laser-cooled atomic ensembles within fiber networks, an important prerequisite for large scale quantum communication schemes. Moreover, it is ideally suited to the realization of hybrid quantum systems that combine atoms with, e.g., solid state quantum devices.

Colloquium: Strongly interacting photons in one-dimensional continuum (2016, background): “…strong coupling to single emitters in 1D can also be achieved in an ion trap (Meir et al., 2014), with cold atoms trapped inside (Bajcsy et al., 2009) or near (Vetsch et al., 2010) an optical fiber, or with single molecules doped in an organic crystal inside a glass capillary (Faez et al., 2014).”
Quantum matter built from nanoscopic lattices of atoms and photons (2018, background): “…also been an effort for over a decade to migrate from free space to microphotonic and nanophotonic platforms (Aoki et al., 2006; Nayak et al., 2007; Vetsch et al., 2010; Volz et al., 2011; Goban et al., 2012, 2014; O’Shea et al., 2013; Thompson et al., 2013; Shomroni et al., 2014) for a number of…”
Exponential Improvement in Photon Storage Fidelities Using Subradiance and “Selective Radiance” in Atomic Arrays (2017, background): “While cold atoms can now routinely be trapped near dielectric structures [29,47,80,112,113], the filling fractions remain quite low and new approaches (such as integration with tweezer arrays) must be developed to achieve near-perfect filling.”
Subradiant states of quantum bits coupled to a one-dimensional waveguide (2018, background): “Superconducting qubits coupled to photons propagating in open transmission lines [1–3] offer a platform to realize and investigate the fascinating world of quantum light-matter interactions in one dimension – so-called “waveguide quantum electrodynamics (QED)” [4–11].”
