Periodic Reporting for period 1 - SinglePass (A cold-atom photonic-crystal-waveguide interface for efficient quantum operations in single pass)
Okres sprawozdawczy: 2021-03-01 do 2023-02-28
SinglePass aimed at coupling atoms to Photonic Crystal Waveguides (PCW) exhibiting slow modes for enhancing the atom-light coupling. Reaching the strong coupling regime with such a waveguide quantum electrodynamics (wQED) platform with atoms offers the prospect of realizing for instance an all-guided single-photon transistor in single pass.
The fellow obtained a permanent academic position during the course of the fellowship, which led to the early termination of the action.
A critical requirement for reaching the strong coupling regime in this wQED platform is to trap the atoms in the evanescent field of guided modes. A significant step was attained to this end by the development of a Python package for computing such dipole traps: nanotrappy. This package was used to design the PCWs that will be used, and has been made available in open source to the community.
