From: Dynamics of probing a quantum-dot spin qubit with superconducting resonator photons

(a) (left) The energy level diagram of the spin single-triplet qubit in double quantum dot. (right) Schematic showing the sequence for coherent control of the spin qubit and measurement of the resonator signal. (b) The phase of resonator field Ï• as a function of the measurement time tm. The signal shows the resonator response dynamics, conditioned on the spin qubit state. (c) The phase of resonator field Ï• as a function of the gate operation time tp, showing coherent oscillations of spin qubit states.
