Chamath’s 8k qubit figure doesn’t seem right to me, way too low. Not really worried about it yet. Lots of Snake Oil vibes. Not an expert on quantum computing though.
quoting note13cm…2l39I wanted to see for myself how long it would take various strengths of quantum computers to brute force a single SHA256 hash. I couldn’t find any comprehensive research, so after finding a couple data points from Bitcoin news sources, I extrapolated the rest.
From what I can tell, the strongest quantum computer currently is ~1k qubits. However, there appear to be many, many caveats. Ex. All qubits aren’t made equal. I’m also not a quantum computer expert at all. These calculations could be way off. Corrections welcome.
