This is part of the reason I like that the first phase of Google's current quantum computer roadmap is "physics derisking" [1]. There's no known reason that it should be impossible to make a thousand qubits dance together in a highly controlled way and get the expected results, but maybe there are some unexpected or unknown obstacles. That being said, if physics derisking failed, it seems really unlikely to me that it would be because quantum mechanics itself was wrong as opposed to there just being some unforseen problematic error mechanism that was consistent with quantum mechanics. Finding a flaw in quantum mechanics itself would be a scientific revolution, which would be awesome, but those are also pretty rare. I also think it's a little telling that people keep thinking it's the philosophically unsatisfying parts of quantum mechanics that are going to break, when entering a new regime. It smells of confirmation bias. Disclaimer: am on google quantum team. 1: https://youtu.be/VvHh6GoNhy8?t=311 https://youtu.be/VvHh6GoNhy8?t=311
