Reality check: no one has ever built a quantum computer with qubits lasting more than a tiny fraction of a second, and quite possibly they never will.

First, you're more than able to do a literature search yourself. Second, shifting goalposts. Third, here. 8.7 (7) spic.twitter.com/Jl7EwetFUG
Thank you for confirming that you have no peer-reviewed evidence of a working quantum computer with long-lasting qubits.

Figure 8g, 10qubit parallel operations. We've been operating with 1s+ coherence since 2013. We achieved 9s last year (data provided). https://iopscience.iop.org/article/10.1088/2058-9565/abdca6 …pic.twitter.com/phG0tqXmap

You started with an important premise - that building QCs is VERY hard, and that many systems (like those from Goog/IBM) do have microsecond coherence times. But you made a specific factual assertion about current and future status of QC that's not correct. Have a good day.

Curious why when presented with lots of instances of qubits with seriously long coherences your focus is on them not being “true” quantum computers currently rather than the fact that it makes your “and they likely never will” statement look extremely hollow
