From: Experimental filtering effect on the daylight operation of a free-space quantum key distribution
Performance optimization with the temporal filtering technique in daylight. The FOV is fixed at 283 μrad. (a) QBER as a function of the valid size of the signal window. (b) Sifted and secure key rates as functions of the valid size of the signal window. (c) Performance of the QBER and key rates with the optimal signal window size.
