Fig. 4: Stokes detection probability and Stokes–anti-Stokes coincidence probability.

a Blue squares are the measured values of Stokes detection probability \(P_S^{(m)}\) as a function of the number of modes m. b Blue squares are the measured values of Stokes–anti-Stokes coincidence probability \(P_{S,AS}^{(m)}\) as a function of the number of modes m. The errors associated with the data correspond to one standard deviation of the measured value and are smaller than the data points displayed.
