Rigetti has systematically
increased gate fidelity on
cloud-deployed systems.
Additional fidelity will be
achieved via integrating faster
gates and longer coherence.

The achievable gate fidelity
for superconductors based on
best-shown components is
>99.99%, approximately 50x
better than requirement for
fault-tolerance.
