From Space to Quantum: India’s Next Big Leap into the Future of Technology

When India announced its National Quantum Mission in 2023, it barely made a ripple amid headlines dominated by elections, wars, and the relentless march of artificial intelligence. Yet in hindsight, I believe this will stand out as one of the most consequential decisions India has made in decades.

I say this not as a casual observer but as a physicist who spends his days thinking about the quantum world. A few days ago, listening to Prime Minister Narendra Modi’s speech on National Space Day, I was struck by how far India’s space program has come—and how quickly. The quantum mission, if pursued with the same grit, could be even more transformative.

For most people, the word quantum sounds mysterious, almost mystical. But it is not magic—it is physics at its strangest. At the atomic level, particles can exist in two states at once, or remain entangled across great distances. Harnessing these rules allows us to build machines that can outpace supercomputers, create communication networks that cannot be hacked, and design sensors of unimaginable precision.

That is exactly what India has set its eyes on: quantum computers with 50 to 1000 qubits, unhackable satellite-based links stretching 2000 kilometers, and quantum sensors that could change the game in healthcare, navigation, and defense. These are not small goals; they are audacious ones.

Why does this matter so much? Because we’ve seen this story before. In the 1950s, nations that mastered semiconductors wrote the rules of the modern economy. In the 1980s, those who embraced the internet early—first the U.S., later China—didn’t just benefit, they reshaped global geopolitics. Quantum technology is at a similar inflection point today.

If India merely sits back and imports quantum machines from elsewhere, it will be a follower. But if it builds them, it will be a rule-setter. That is the difference between being a consumer of history and being its author.

The encouraging part is that India has already begun. Four hubs have been set up at IISc Bengaluru, IIT Madras, IIT Bombay, and IIT Delhi, bringing researchers together in a way that Indian science has often lacked. Startups, too, are stirring. QpiAI in Bengaluru has already built a 25-qubit system. ISRO and DRDO are experimenting with secure quantum communications. Andhra Pradesh has declared its ambition to build a “Quantum Valley” in Amaravati. These may be small steps, but they are in the right direction.

Yet, let’s not romanticise this. Building quantum hardware is one of the hardest challenges in science today. It is not like writing software, where India has excelled. It requires materials science at the atomic scale, world-class fabrication facilities, and patient investment that may take decades to bear fruit. The ₹6,000 crore budget is significant, but the real question is whether this mission can survive the churn of politics, budget cycles, and the impatience of short-term thinking.

From where I stand, India has one unique advantage: it can do this differently from the United States or China. In America, quantum research is dominated by private giants like Google and IBM. Innovation is real, but it is also locked behind corporate walls. India, instead, is building a model where universities, public labs, startups, and the government work together. That is a strength. It could create a more open and collaborative ecosystem—something the world badly needs.

And here is where my personal conviction comes in. I do not see India’s quantum mission as merely India’s story. Just as India became the “pharmacy of the world” by producing affordable medicines, it could become the world’s trusted provider of quantum technologies—developed not just for the rich, but with the realities of the Global South in mind. Imagine affordable quantum-secure communications in Africa or Latin America, or low-cost quantum sensors revolutionizing agriculture in Asia. That would change not just India’s destiny, but the world’s.

The lesson of quantum mechanics is that nothing is certain, only probable. The same holds true for India’s mission. It may stumble; it may take longer than planned. But if India succeeds, it will not only catch up with the United States and China—it will stand alongside them as a leader of the next technological revolution.

The story of India’s space program shows us what is possible when ambition meets persistence. Chandrayaan-3’s landing on the Moon in 2023 was not just about space. It was about belief. The National Quantum Mission carries the same spark, perhaps even brighter.

India has chosen to leap into the quantum future. My view is simple: the rest of us should not just watch. We should engage, collaborate, and recognize that this is not just India’s chapter to write—it is a chapter for all of humanity.
