About Research:
- Researchers at Raman Research Institute (RRI), Bengaluru, led by Dr. Urbasi Sinha, have developed new quantum techniques to generate and certify truly random numbers.
- Dr. Sinha’s team achieved device-independent quantum random number generation using quantum entanglement.
- Significance of Random Numbers
- Random numbers form the basis of encryption systems, passwords, and digital authentication.
- Most current systems use pseudorandom numbers, generated by algorithms — not truly random, hence vulnerable to quantum computing attacks.
- The Quantum Advantage:
- True randomness arises only from natural or quantum processes, not from algorithms.
- Quantum systems can generate randomness using the behaviour of photons or subatomic particles.
Implications:
- Can enable hack-proof digital and online security systems.
- Has strategic, commercial, and cybersecurity significance for India.
- Marks a key outcome under India’s National Quantum Mission.
Why in News?
- Indian scientists at Raman Research Institute achieved a global breakthrough by demonstrating true random number generation on a quantum computer, a step toward unhackable digital security.
