Micro-LEDs Achieve Gigabit-per-Second Quantum Random Number Generation

Researchers from Saudi Arabia and the US have demonstrated a micro-LED-based quantum random number generator (QRNG) achieving an unprecedented 9.375 Gbit/s generation rate. Leveraging intensity fluctuations in the spontaneous emission of blue GaN micro-LEDs, the system passed rigorous NIST tests. Its compact, reliable, and energy-efficient design makes it promising for applications requiring high-speed random number generation, such as data encryption and complex simulations. Future work involves integrating a 2D array of micro-LEDs for parallel generation and creating a fully integrated QRNG chip.
