From: Dynamics of probing a quantum-dot spin qubit with superconducting resonator photons
(a) Schematic of two-electron spin single-triplet qubit in double quantum dots coupled to photons in a transmission line resonator. The control pulse for the spin qubit can be applied through the gate voltage of the quantum dot. In realistic setup, the spin qubit is influenced by the decoherence effects from the environment noises. The state of the spin qubit can be effectively determined by measuring the signal of a microwave field transmitted through the resonator. (b) For this spin-photon coupled system, the effective transverse coupling gx and longitudinal coupling gz are plotted as functions of the gate voltage \(\epsilon \) and inter-dot tunneling Tc.
