Dual Quantum Random Number Generator using a FPGA for QKD-CV systems: Preliminary results

This paper presents the preliminary results of a dual quantum random number generator using a FPGA DE0 Nano and optical set-up experiment with variable transmission rate from 10 to 50 Mbps using coherent detection to detect the quadrature components in a simultaneously way of an optical vacuum state using a 90 degree optical hybrid. The main application for this type of system is the quantum cryptographic systems of second generation and all activities where two random sequences requiring speeds of about 50 Mbps are necessary. Finally, the performance of the overall systems is determined measuring the bias probability (0.0002±0.000001) of the finals random binary sequences.
