Based on some investigation, I have found the best qubit coherence timescales, in superconducting architectures, to be the order of milliseconds. https://journals.aps.org/prb/abstract/10.1103/PhysRevB.94.014506 Considering the gate operation timescales, typical qubit error rates per gate operation are in order of 0.001 to 0.01.
And the trapped ion qubit here supposedly has one hour coherence time https://www.nature.com/articles/s41467-020-20330-w However, gate timescales are not clear.
Are qubit error rates per gate operation in order of 0.001 to 0.01 the state of the art? Please share coherence timescales and gate timescales for other modern qubits if you know.
