a Experimental and (b) theoretical results of an element ∣ρ03∣ of the density matrix with respect to the normalized evolution time γt and the ratio Ω/γ. c Curve fitting using the damped sinusoidal function for experimental data (circles) at Ω/γ = 5. The inset shows the fitting results using the hyperbolic sine function at Ω/γ = 0.5. The experimental data are averaged over 400 repetitions with error bars representing the standard deviation. d Fitted oscillation and decay factors B1 or B2 with respect to Ω/γ. The error bar, which is smaller than the symbols, denotes the 95% confidence intervals of the fit.
