Road to an all-optical single-photon gate using long-range Rydberg interactions — •Charles Möhl and Charles Adams — Durham University, United Kingdom

Due to their tunable long-range interactions, Rydberg atoms are ideal candidates for realising an all-optical single-photon controlled-z gate. The physical building blocks are electromagnetically-induced transparency (EIT) for photon storage and retrieval as well as Rydberg blockade caused by resonant dipolar or van-der-Waals interactions, both together enabling effective photon-photon interactions. In a previous work our group demonstrated correlations between photons after storage in and retrieval from two spatially separated Rydberg atom clouds (H. Busche et al., 2014, 10.1038/NPHYS4058). The system is further investigated as ways to reach the single-photon blockaded regime are explored.
