**Quantum Leap for Cybersecurity: Scientists Develop Traceable Random Numbers Using Entangled Photons**

**Sri City, August 5, 2025** – In a breakthrough for cybersecurity, a team of researchers has unveiled a new method for generating truly random numbers using quantum mechanics and blockchain technology. This innovation addresses a long-standing challenge in online security: creating unpredictable encryption keys that are resistant to hacking.

The current standard, pseudorandom number generators, relies on algorithms that, while seemingly random, can be predicted if the starting point is known. Traditional methods such as the lava lamp method used by cybersecurity company Cloudflare, while providing a degree of unpredictability, are still ultimately governed by deterministic physics.

Recognizing the inherent randomness of quantum mechanics, scientists at the University of Colorado, Boulder (CUB) and the National Institute of Standards and Technologies (NIST) have harnessed the properties of quantum entangled photons. By measuring the polarization of these photons, a process inherently random, they generate a string of numbers.

To ensure the integrity of the process, the team integrated blockchain technology. This innovative approach creates a traceable cryptographic contract, enabling independent verification of each step in the random number generation process.

“Every step can be audited and verified,” said Peter Bierhorst, a quantum information theory researcher at the University of New Orleans, calling the work “innovative.”

While the technique is a significant step forward, experts caution that it is currently limited in scale. Sanjit Chatterjee, an information security researcher at the Indian Institute of Science, Bengaluru, noted that the current output is “nowhere near” the volume of random numbers needed for everyday operations. The complex equipment required also presents a challenge for widespread commercial deployment.

Despite these limitations, the research holds immense promise for the future of cybersecurity. As Gautam A. Kavuri, the lead researcher at CUB, aims to decentralize trust further, he looks forward to adding to their Twine protocol. This method will create a secure and trustworthy foundation for encrypting data and safeguarding personal information in an increasingly digital world. Experts predict that this quantum-powered encryption could become more commonplace in the coming years.
