Experimental estimation of tunnel coupling. Starting with ρ↑↓, the measured probability P↑↓ (a) and the theoretical prediction (b) as a function of pulse wait time and detuning position. For the model we have used a value of tc = 200 MHz. c Solid green and blue curves show theoretical predictions for wait times of 0.3 and 1 ms respectively (corresponding cuts shown in a). Blue and green crosses show measurements for these wait times. The dashed and dotted lines show the theoretical predictions for tunnel coupling values of tc = 500 and 50 MHz respectively
