Yes, NASA Did Help Achieve Quantum Supremacy

Quantum supremacy using a programmable superconducting processor, Nature

"Our Sycamore processor takes about 200 seconds to sample one instance of a quantum circuit a million times--our benchmarks currently indicate that the equivalent task for a state-of-the-art classical supercomputer would take approximately 10,000 years. This dramatic increase in speed compared to all known classical algorithms is an experimental realization of quantum supremacy for this specific computational task, heralding a much-anticipated computing paradigm."

Quantum Supremacy Using a Programmable Superconducting Processor, NASA

"Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits ... While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task."

Keith's note: A month ago I noted that a paper on this achievement was posted and then removed by NASA from NTRS. It had Eleanor G. Rieffel as an author - as does this Nature apaper - the titles are identical. Let's see if NASA bothers to mention their role in all of this - or not. When I asked PAO about this a month ago they did not want to talk about it. I wonder if they even know it has been published.
