Figure 1
(a) Schematic of a singly charged QD inside a single-sided cavity, interacting with a photon (input and output field operators: \(\hat{b}_{{{\text{in}}}}\) and \(\hat{b}_{{{\text{out}}}}\)), with a side-leakage rate (\(\kappa_{s}\)) of cavity mode and decay rate (\(\gamma\)) of \({\text{X}}^{ - }\). (b) By the spin selection rule in the QD, the induced interaction is \(\left| \uparrow \right\rangle \to \left| { \uparrow \downarrow \Uparrow } \right\rangle\) (\(\left| \downarrow \right\rangle \to \left| { \downarrow \uparrow \Downarrow } \right\rangle\)), according to the photon polarization of \(\left| L \right\rangle\) (\(\left| R \right\rangle\)).
