Fig. 3: Fidelity data of AI-optimized memory.
From: AI-assisted hyper-dimensional broadband quantum memory with efficiency above 90% in warm atoms
Fidelity as a function of the delay time for OAM (a) and SAM (b). The delay time is the time difference between W and R pulses, the error bars are the standard deviation of 10 consecutive acquisitions. The inset of (b): intensity of horizontal polarization of before and after memory as the polarization angle changes from 0 to 2π. c The projection results of SAM information encode on OAM (l = 2) of \({S}_{in}^{{\prime} }\) and SR signals. \({S}_{in}^{{\prime} }\) is the Sin signal passing through the whole optical path without memory by blocking pump field.
