Electromagnetic Information Leakage of a Quasi-Quantum Key Distribution Receiver

This dataset contains 1200 records of 2500 samples classified into 4 labels. The dataset contains 600 measurements per antenna of radiated signals of the quasi-Quantum Key Distribution (QKD) receiver. That is a total of 1200 measurements of time-domain signals captured by both antennas. Each record is a vector of 2500 samples of the amplitude measured by the oscilloscope that ranges between -10 and 10 mV. The records are either noise or a signal carrying the emission radiated by one of the four SPADs in the quasi-QKD receiver during each acquisition. Each record is associated with one SPAD or noise with a label. Labels 1, 2, 3, or 4 are the corresponding SPAD and 0 is noise.
