Fig. 2: Coupling cavity photons to multiple electronuclear spin transitions in [Yb(trensal)].
From: High cooperativity coupling to nuclear spins on a circuit quantum electrodynamics architecture
a Color plot of the microwave transmission measured at T = 10 mK near the bare resonance frequency fr = 2.93 GHz of a LC superconducting resonator and as a function of the magnetic field. Changes in the resonator mark the coupling of cavity photons to different electronic spin transitions. The crystal had a x = 5% Yb nominal concentration. The lines assign each of the observed features to the different Yb isotopes naturally present in this crystal b Same as in a for a fr = 548.5 MHz resonator and a crystal with x = 8%. This LC cavity is specifically designed to optimally couple to nuclear spin transitions in [173Yb(trensal)]. Some of them are identified in the caption. Color scale bars indicate the amplitude of the transmitted signal in relation to the input signal on a logarithmic scale.
