Subradiant states for two imperfect quantum emitters coupled by a nanophotonic waveguide

Coherent interactions between quantum emitters in tailored photonic structures is a fundamental building block for future technologies, but remains challenging to observe complex solid-state environments, where the role of decoherence must be considered. Here, we investigate optical interaction two mediated by one-dimensional waveguides realistic environment, focusing on creation, population, and detection subradiant state, presence dephasing. We show that as dephasing increases, signatures subradiance quickly vanish intensity measurements, yet remain pronounced photon correlation particularly when are pumped separately so populate state efficiently. The applied Green's tensor approach used model crystal waveguide, including dependence spatial position integrated emitter. work lays out route experimental realization states nanophotonic containing emitters.
