1 Product Overview
The quantum random number generator EQT-PQR01G is a board-type true random number generator independently developed by our company, based on the principle of pulsed phase fluctuation. The EQT-PQR01G uses phase fluctuations of a pulsed light source as the quantum random entropy source, combined with signal detection and data post-processing, to output quantum random number sequences. The board employs a standard PCIe 2.0×1 hardware interface.
This product can be applied to quantum random number output and device debugging, featuring high speed, stability, compact structure, and easy-to-use interfaces, providing a reliable source of quantum random numbers for applications such as internal network data transmission and information data encryption. The appearance schematic is shown in Figure 1-1.
