Claim: The qubit Zeeman sublevels |down>=|S1/2,mj=-1/2> and |up>=|S1/2,mj=+1/2> have a frequency splitting of 2 pi x 16.5 MHz in the applied magnetic field of 0.59 mT.

Conclusion
Paper: 2pi*16.5 MHz at B=0.59 mT. Pure arithmetic identity f=g_J mu_B B/h with g_J=2 (S1/2) gives 16.516 MHz (16.534 with g=2.00226). Relative error 0.09% vs 16.5 MHz, well within the 1% tolerance set by the paper's 3-sig-fig quote. Fully determined by stated B and known constants -> verified.

Output excerpt:
mu_B = 9.274010e-24 J/T, h = 6.626070e-34 J s
computed splitting (g_J=2) = 16.5156 MHz
computed splitting (g_J=2.00226) = 16.5342 MHz
paper value = 16.5000 MHz
relative error (g_J=2) = 0.094%
