**Summary:**

Researchers at the Raman Research Institute have successfully generated certified random numbers using IBM’s cloud-based quantum computers. This breakthrough demonstrates that even current, noisy intermediate-scale quantum (NISQ) computers can perform tasks impossible for classical machines, specifically generating truly random numbers certified by quantum mechanics. The team used a single qubit and shallow circuits to violate the Leggett-Garg inequality, confirming the randomness. This achievement has significant implications for data encryption, secure communication, scientific simulations, and the advancement of quantum technology, as it showcases the practicality of quantum mechanics in addressing real-world problems and offers a new way to benchmark qubits.

**Quantum Leap: Indian Researchers Generate Certified Random Numbers Using IBM Quantum Computers**

**CHENNAI, October 11, 2025** – In a groundbreaking achievement, researchers at the Raman Research Institute have demonstrated the ability to generate certified random numbers using publicly accessible quantum computers from IBM. This breakthrough, published in *Frontiers in Quantum Science & Technology*, marks a significant step forward in harnessing the power of quantum mechanics for practical applications, particularly in fields requiring uncompromised randomness, such as cryptography and scientific simulations.

The team, led by Professor Urbasi Sinha, Head of the Quantum Information and Computing (QuIC) lab, leveraged the unique properties of quantum mechanics to overcome the limitations of traditional random number generators. Conventional computers rely on algorithms that produce pseudo-random numbers, which are predictable given the initial seed. In contrast, the researchers used a single qubit on IBM’s quantum computers and exploited the inherent randomness of quantum phenomena.

“The beauty of our implementation is that we have been able to show something as fundamental as certified randomness using a noisy intermediate scale quantum computer,” Prof. Sinha said. “We have been able to do this through careful error mitigation techniques and ensuring that ‘classical’ errors are under control and the randomness is purely from the underlying quantum mechanical principles.”

Their experiment involved violating the Leggett-Garg inequality (LGI) while adhering to the ‘no signalling in time’ condition, thereby certifying the generated bits as truly random. This approach demonstrates that even with today’s relatively noisy quantum computers, it’s possible to accomplish tasks beyond the reach of classical computers.

The implications of this research are far-reaching. Secure random numbers are crucial for data encryption, secure communications, and various scientific simulations. The ability to generate certified random numbers using readily available quantum cloud platforms opens new avenues for enhancing security and computational capabilities.

Furthermore, the study highlights the importance of error mitigation techniques in improving the reliability of quantum hardware. The team’s success also offers a new method for benchmarking qubits, paving the way for the development of more robust and efficient quantum computers.

“We can use our method as a strong benchmark for new qubit registers as they emerge, which will prove how useful these systems are going to be in solving real-world problems,” Prof. Sinha said.

This discovery underscores the potential of quantum mechanics to benefit society today and represents a significant contribution to both foundational physics and the advancement of quantum technology. The research was conducted using the IBM Quantum platform.
