Willow quantum chip demonstrates verifiable quantum advantage on hardware

"surpassing even the fastest classical supercomputers (13,000x faster)"

"Quantum verifiability means the result can be repeated on our quantum computer — or any other of the same caliber — to get the same answer, confirming the result."

"The results on our quantum computer matched those of traditional NMR, and revealed information not usually available from NMR, which is a crucial validation of our approach."

It certainly seems like this time, there finally is a real advantage?

I’ve only skimmed the paper but it seems like the “information not usually available” from NMR is the Jacobian and Hessian of the Hamiltonian of the system.

So basically you’re able to go directly from running the quantum experiment to being able to simulate the dynamics of the underlying system, because the Jacobian and Hessian are the first and second partial derivatives of the system with respect to all of its parameters in matrix form.
