Abstract
We analyse the entanglement properties of deterministic path-entangled
photonic states generated by coupling the emission of a quantum-dot biexciton
cascade to a chiral nanophotonic waveguide, as implemented by {\O}stfeldt et
al. [PRX Quantum 3, 020363 (2022)]. We model the degree of entanglement through
the concurrence of the two-photon entangled state in the presence of realistic
experimental imperfections. The model accounts for imperfect chiral
emitter-photon interactions in the waveguide and the asymmetric coupling of the
exciton levels introduced by fine-structure splitting along with time-jitter in
the detection of photons. The analysis shows that the approach offers a
promising platform for deterministically generating entanglement in integrated
nanophotonic systems in the presence of realistic experimental imperfections.
