Steady-State Multiparticle Entanglement via Dissipative Engineering in Waveguide QED
This protocol uses collective interactions from subradiant and superradiant states, combined with the quantum Zeno effect, to deterministically generate high-fidelity W-type entangled states in waveguide QED. It achieves this by engineering dissipation to drive the system into a desired steady state without needing external feedback or precise timing.
