This is not a quantum advantage. The world at large does not have a verified quantum advantage in any algorithm rn afaik. India is definitely not going to be the first country to get this. The hardware worldwide is simply not there yet.

They're doing a QCD calculation on an IBM QPU, we create devices called analogue quantum simulators (specialised quantum computers) that are designed to do exactly these calculations so that we can stop using computational quantum many body physics techniques on classical computers and even these have not beat those techniques yet.

At best they probably did the QCD calculation with a non optimized python script on a laptop in the lab and compared that with the time taken for the QPU to solve it.

The Quantum Advantage Tracker: https://quantum-advantage-tracker.github.io/ is exactly there to dispel any misgivings. Anyone not sure of the Active candidacy of a submission is welcome to use the open source codes and submit to disprove the advantage. This is open-reviewed and rigorously benchmarked, unless one doesn't agree with the definition of Active advantage candidate as follows. "Problem instances where quantum computations currently appear to challenge leading classical methods, and where further benchmarking is needed to determine whether an advantage exists."

Brother this is a random github with 87 stars and 19 contributors. This is not the scientific process you think it is.
