    $\begingroup$ different technologies might result in entirely different answers. This sort of thing is better covered by asking individual questions focusing on each technology, imo $\endgroup$

I do not know the reliability of this site and these authors: The Next Decade in Quantum Computing—and How to Play 2018 Philipp Gerbert and Frank Ruess

In the article they provide an extensive summary (2018) of the different technologies and gate fidelities, see exhibit 7: enter image description here

    $\begingroup$ It would be nice if anyone can compile a similar list for the state of art at the year end of 2021. $\endgroup$
