(a) Genuine entanglements of four QEs inserted in the hotspots of five spheres cluster as showed in the inset at ω₁ = 4540 THz and ω₂ = 4950 THz. The corresponding spontaneous decay rate Γ (b) and interference term (c) of QEs with d = 1 nm (solid), d = 2 nm (dashed) and d = 4 nm (dotted), the other parameters are taken identical with those in Fig. 1.
