I came here after reading about the announcement regarding the Sycamore processor and Google's Quantum Supremacy claim. I am hung up on several key things and I am hoping that I could find those answers here, or at least direction to the answers.
First, I am trying to make sense of the comparison, i.e. Sycamore is a 53-qubit processor (54 but 1 is not functional). One the paper itself (doi: 10.1038/s41586-019-1666-5) figure caption 4,
... hereas an equal-fidelity classical sampling would take 10,000 years on a million cores, and verifying the fidelity would take millions of years
I assume this a million cores refers to IBM Summit at Oak Ridge, right?
My actual questions revolve around the power consumption. I assume it takes a lot of power to use that a million cores to simulate quantum state; how much power did the Sycamore consume to perform the same task? In other words, how much power did the Sycamore use along with its other auxiliary/peripheral devices for that span of 200 seconds vs. how much power theoretically Summit would use in the span of 2.5 days (IBM's counter-claim) if not 10,000 years (Google's claim)?
Second question with regard to power consumption, given power consumed as percent fraction, how much power does Sycamore consume, how much goes to the dilution refrigerator?
