Abstract

Coupling to propagating photons has recently emerged as a powerful alternative to cavity-QED for exploring light-matter interaction at the single photon and single emitter level. While the pioneering works have used near-field probes and lenses [1-3], an increasing number of theoretical studies have considered the coupling of emitters to guided modes and have pointed out intriguing quantum phenomena such as multi-photon bound states and photon blockade [4], emergence of fermion-like photons [5], or long-range entanglement between two emitters [6]. On this ground, challenging experiments are pursued for loading cold gasses inside hollow optical fibers [7] or in optical traps around nanofibers [8, 9]. In the solid state, where single emitters can be individually addressed, first steps have been taken to couple colloidal quantum dots to nanofibers [10], but this system suffers from massive dephasing and is not desirable for quantum optical investigations.
