The Indian Institute of Technology Madras (IIT Madras) has developed a silicon photonics-based high-speed Quantum Random Number Generator (QRNG). The institute has also signed an MoU with Indrarka Quantum Technologies to transfer the IP and for commercial deployment of the QRNG technology in a deal worth ₹1 crore.

The technology, developed at the institute’s Centre for Programmable Photonic Integrated Circuits and Systems (CPPICS), is expected to have critical applications in fields such as  defence, cryptographic algorithms, financial transactions, blockchain, and OTP generation. 

“Silicon photonics is an emerging area with a strong interface with Quantum Technologies. Random number generation is a critical building block for secure computing and communication. I am extremely excited that the CPPICS has developed this QRNG that could be readily deployed in the market,” said V Kamakoti, Director, IIT Madras. 

Meanwhile, a prototype version of the QRNG module was earlier delivered to the Young Scientist Laboratory – Quantum Technologies under the Defence Research and Development Organisation. The institute has also developed an advanced version of the QRNG module, which was deployed at the Society for Electronic Transactions and Security (SETS Chennai) for quantum security applications.

According to Dinanath Soni, Director, Indrarka Quantum Technologies, “We are committed to making this indigenous innovation accessible across critical sectors, establishing India as a global leader in quantum security and advancing our nation’s vision of technological self-reliance.
