a Wavefunctions and Wigner functions of the synthesized state with n = 16. From the left, N = 1, 2, 3, 4 and N = 4 followed by a damping operaiton. The broken lines are the wavefunctions of the target state. b No-error rate of theoretical and simulated \(\left\vert {\tilde{0}}_{\Delta ,\Delta }\right\rangle\) state. Round dots are the results with various (n, N) under c = 1. the star-shaped points are the result with (n, N) = (16, 4) under c ≠ 1. c Wigner functions of the synthesized magic states over 10 dB squeezing.
