A quantum computer just did in 20 seconds what took a classical machine 2 hours.
No contrived party trick.
A real physics problem.
And the scientist behind it isn't in Silicon Valley or MIT.
She's in Goa.
Meet Dr. Indrakshi Raychowdhury, associate professor at BITS Pilani.
Her team just did something no Indian lab has ever done before.
Quarks. Gluons. The strong nuclear force.
Particles inside a proton, mutually shoving each other in real time.
Classical computers can snapshot them fine.
But watching them move, frame by frame?
Exponentially hard.
So her team flipped the script.
They used a quantum computer to imitate a quantum system.
Quantum computers are terrible at simple arithmetic.
Adding two numbers? Painfully slow.
But simulating a chaotic, interacting quantum system?
That's exactly where they shine.
"That is highly counterintuitive," she said, "but it is where quantum advantage lies."
Enter the Quantum Advantage Tracker — IBM's watchdog, launched November 2025.
Submit a result. A committee tries to break it, on classical and quantum machines.
Stricter than peer review.
Her result is one of them.
The first ever from an Indian lab.
CERN has taken notice.
She's headed to Switzerland next month, invited to see if her method can push their simulations further.
And the algorithm was built to travel.
"If someone gave me a 1,000-qubit computer today, our algorithm would scale to it seamlessly," she says.
Here's the part that stings a little.
India's National Quantum Mission has ₹6,003 crore behind it.
But India still doesn't own a high-end quantum computer.
Every run happened over the cloud, on IBM's hardware, from a desk in Goa.
No lab. No supercomputer. Just an algorithm.
Turns out, the hardware was never the hard part.
That's all for now!
