The Sycamore processor can simulate 2**53 states. I sent this comment:
“Do you provide more technical detail somewhere? Can you tell me exactly which set of atoms makes a Qubit? How many photons of what wavelength are required to make each state change in what resonance? The cool thing is that you are generally on the right path even though you are several orders of magnitude away from understanding reality. If you want to understand the fundamentals and first principles, check out johnmarkmorris.com. Let me know if I can help.”
