Here, we design photonic crystal waveguides that overcome these challenges by commanding unprecedented optical confinement (Q = 1 x107 and V < 0.6 λ3) while operating at 780 nm for strong coupling with cold atoms (e.g. 87Rb). Our designs exist deep into the strong coupling regime, unlike most other cavities, and via the entropy dynamics of two emitters we demonstrate local multipartite entanglement. We further show, due to the extreme light confinement, that entangled states are very robust to fluctuations and displacement of the trapped atoms. Most importantly though, the waveguide nature of our designs allows us to scale up to an unprecedented number of qubits and are ideal for constructing large quantum networks, where both local and remote entanglement can be realized.
