Fidelity of the QST process for the multimode Dicke model. Time-evolution of the QST fidelity \({ {\mathcal F} }_{{\rm{QST}}}\) between the states \(|\chi \rangle =\,\cos \,\theta |\uparrow \rangle +\,\sin \,\theta {e}^{i\varphi }|\downarrow \rangle \) and \({\rho }_{{Q}_{2}}(t)\), averaged over the Bloch sphere. We have considered the multimode Dicke mediator initialized in a thermal state at T = 100 mK.
