Key Takeaways
- Google’s Willow quantum chip solved previously impossible equations 13,000x faster than supercomputers
- India allocated ₹4,500 crore for quantum research with potential budget increases
- Quantum computing threatens current encryption standards, creating urgent cybersecurity challenges
- Global race intensifies as US and India invest heavily in quantum technology development
Quantum computing has moved from theoretical concept to practical reality with Google’s recent breakthrough, marking a technological shift that could redefine computational power as we know it.
On October 24, Google announced its Willow quantum computing chip achieved what was considered impossible – solving complex equations 13,000 times faster than the world’s most advanced supercomputers. This milestone signals quantum computing’s arrival at the application stage.
“What we’re witnessing globally is not just a race for faster computation, but a redefinition of what computational power itself means. (These) breakthroughs mark the beginning of a new era of scientific enterprise, where advances in physics, information science, and capital investment are finally moving in step,” said Professor Bhanu Das, director (CQuERE) at TCG Centres for Research and Education in Science and Technology (CREST), Kolkata.
What Makes Quantum Computing Different?
Unlike traditional computers using binary bits, quantum computers employ qubits that exist in multiple states simultaneously. This quantum advantage enables real-time error correction, accelerates drug discovery, improves climate modeling, and enhances financial forecasting accuracy.
The United Nations’ designation of 2025 as the International Year of Quantum Science and Technology appears increasingly prescient as developments accelerate.
Global Quantum Race Intensifies
India has allocated ₹4,500 crore for advanced technology research including quantum computing, with indications of further budget increases. Simultaneously, the Trump administration announced funding for American quantum companies in exchange for equity stakes, aiming for global leadership in this breakthrough technology.
India’s National Quantum Mission, semiconductor manufacturing initiatives, and the Quantum Research Park at IISc Bengaluru demonstrate the government’s strategic focus. Despite current limitations, India is positioning itself as a niche player developing smaller, efficient quantum computers with specialized applications.
The Cybersecurity Imperative
The Indian IT ministry and CERT-IN recently published a quantum computing white paper emphasizing cybersecurity concerns – for good reason.
“Quantum security is moving from theory to reality faster than many expected. The fact that governments like the US and India are now actively exploring funding for quantum technologies shows how strategic this field has become. It’s no longer just about research — it’s about national security, digital sovereignty, tech sovereignty, data protection at rest and transit, and future-proofing our digital world,” said Sudiptaa Paul Choudhury, CMO of QNu Labs, Bengaluru.
As quantum computing matures, current encryption standards protecting banking, email, and communications become vulnerable to rapid decryption.
“Today’s security relies on mathematical problems that would take classical computers millennia to solve, but quantum machines could crack them in hours,” pointed out IC Santhosh Sivasubramani, senior member of IEEE, the New York-headquartered technical professionals organization.”As quantum computers inch closer to practical reality, the encryption protecting everything from bank accounts to private communications becomes vulnerable. Even the Signal Protocol, the open-source encryption standard trusted by billions across messaging platforms, would crumble against a sufficiently powerful quantum machine,” he added, quipping, “We are essentially in a race to redesign our digital locks before quantum computers can pick them, and unlike software updates, this requires rethinking the fundamental architecture of how we protect information.””The question isn’t whether quantum computers will break current encryption, but whether we’ll have quantum-resistant alternatives deployed before they do,” he said.
This new technological frontier presents both unprecedented opportunities and urgent challenges, creating a global race where the stakes couldn’t be higher.
