A collaborative team of scientists from King Abdullah University of Science and Technology (KAUST) and King Abdulaziz City for Science and Technology (KACST) has achieved a groundbreaking milestone in data security. The researchers have developed the world’s fastest quantum random number generator (QRNG), according to international performance standards.
QRNG
In a statement from KAUST, the university announced that their QRNG successfully passed the rigorous randomness tests set by the U.S. National Institute of Standards and Technology (NIST). The device generates random numbers at speeds nearly 1,000 times faster than existing QRNGs.
“This marks a major breakthrough for industries that rely on robust data security,” said Professor Boon Ooi of KAUST, lead author of the study published in Optics Express.
Random number generators are essential for secure applications in sectors like healthcare, finance, and defense. However, conventional systems often rely on “pseudo-random” algorithms — complex but ultimately predictable computations. In contrast, QRNGs use quantum mechanics to generate truly random numbers, making them inherently more secure.
“Unlike traditional systems, quantum random number generators don’t just appear random — they are fundamentally unpredictable due to their quantum basis,” explained Professor Ooi.
The team’s record-setting performance was made possible by innovative advances in both device fabrication and post-processing algorithms. Their QRNG utilizes ultra-small micro-LEDs — only a few micrometers in size — which significantly lower power consumption and enhance portability, enabling broader deployment across various technologies.
Dr. Abdullah Almogbel, a contributing researcher from KACST’s Microelectronics and Semiconductors Institute and Director of the Center of Excellence for Solid-State Lighting, emphasized the project’s alignment with Saudi Arabia’s Vision 2030.

“KACST is dedicated to advancing applied research that supports national goals, especially in positioning the Kingdom as a global leader in strategic fields like quantum-enabled technologies,” said Almogbel. “Research like this has the potential to deliver high value across multiple industries and enhance Saudi Arabia’s global competitiveness.”
National Institute of Standard and Technology (NIST), an internationally recognized authority in measurement standards, sets the benchmarks used to validate the quality and integrity of random number generators.
