Multiparticle Entanglement in Waveguides

We present two schemes for the dissipative preparation of multiemitter entangled states in a waveguide. These schemes include: (i) a protocol for preparing a maximally entangled state between two atoms, and (ii) a protocol for generating a W entangled state among three emitters. Starting from arbitrary initial states, both protocols drive the system to a steady-state entangled configuration. We provide an analysis of the final fidelity based on the waveguide parameters, and identify the intrinsic errors associated with each protocol. Additionally, we explore potential experimental challenges. To conclude, we discuss the scalability of the second protocol.
