Figure 4: Two qubit level scheme and decay channels.
From: Observation of Dicke superradiance for two artificial atoms in a cavity with high decay rate
(a) Eigenstates in the coupled basis. All allowed transitions happen via the bright state. The dark state does not couple to the cavity field mode.(b) Eigenstates in the uncoupled basis. The transition rates are always proportional to the number of excitations in the system.
