Q: "Ask HN: What's the Equivalent of 'Hello, World' for a Quantum Computer?" https://news.ycombinator.com/item?id=22707580 [ IBM Qiskit, Microsoft Q#, Google TFQ TensorFlow Quantum, Google Cirq ([NumFOCUS,] SymPy) ]

A: Set a register to zero and see how many times it reads as zero: A) in the local software simulator; and B) with just one modern day qubit register.
As far as I know, nobody in the industry is making absurd claims about their current offerings. That said, some claims of projected growth I've seen appear to be batshit.
And, I believe that you're wrong: Google's quantum supremacy result appears to be genuine, and IBM's refutation was, essentially, "we can use a ginormous supercomputer to match that" -- not your ordinary desktop.
