a Model of a singlet-triplet spin qubit from circuit perspective. b System eigenenergies as a function of detuning for zero (solid black lines) and non-zero magnetic field (dashed green lines). c Admittance for varying gate voltages and magnetic field at zero (ground state) and finite temperature for slow (center) and fast (right) relaxation, showing PSB and its lifting. The dashed line shows the signet-triplet crossing where \(2g{\mu }_{{\rm{B}}}B=\sqrt{{(2{t}_{{\rm{c}}})}^{2}+{\varepsilon }_{{\rm{DQD}}}^{2}}\). The system is probed at 500 MHz with tc = 7 GHz.
