(a) A singly charged QD inside a single-sided cavity interacting with a photon where the decay rate (γ) of X− and the side leakage rate (κ s ). (b) The spin selection rule for optical transitions of X− in the QD \(|\uparrow \rangle \to |\uparrow \downarrow \Uparrow \rangle \) (\(|\downarrow \rangle \to |\downarrow \uparrow \Downarrow \rangle \)) is driven by the photon \(|L\rangle \) (\(|R\rangle \)).
