Spin dephasing 1/Tφ as a function of detuning. a 1/Tφ as a function of detuning \(\epsilon _0\) due to tunneling noise (TN) only or detuning noise (DN) only. For tunneling noise, we choose representative values ∂t0/∂Eb = 10−2 (Dashed), 10−3 (Dotted), and 10−4 (Dash-dotted). b J/(2ħ) and 1/Tφ as a function of detuning \(\epsilon _0\), where A = (2 μeV)2 and ∂t0/∂Eb = 3.2 × 10−3. The dots are the experimental data for J/(2ħ) (circle) and 1/Tφ (square).15
