Methodology for increasing the qubit preparation fidelity. Single-qubit preparation fidelity in terms of the length of the DFG waveguide (L), the bandwidth of pump 1 (\(\sigma _1\) ), and the length (\(l_c\) ) and reflectivity (\(R_i\)) of the SFWM cavity, for \(\sigma _2 = 0.5\) THz and \(\sigma _f=4\) THz. The black circle marker indicates the combination of parameters we choose for our example.
