Describe the fix.

The job limits have changed since the rollout of gen3 engine stack. The new Maximum executions is 10 million, and the new Maximum number of two-qubit gates per job is 400k per circuit (not per job) for static circuits and 100k for dynamic circuits. We no longer have a Maximum number of low-level instructions per qubit (at least for now).

@jyu00 - this applies to every job? Even on systems that don't support gen3?

[jyu00]

Gen3 is now enabled on all backends except the 4 dedicated ones - cleveland, kawasaki, quebec, and rensselaer. We can list them as exceptions. I was kind of hoping we'll have it on them by the time this update goes live 😄

we should also update the options page accordingly: https://quantum.cloud.ibm.com/docs/en/guides/runtime-options-overview#experimental-option-note

@jyu00 is this pph still accurate, or is it being replaced wholly by "400k per circuit (not per job) for static circuits and 100k for dynamic circuits"?:

This ensures that the job can be manipulated within the memory limits of the low-level software stack. The precise limit depends on the options selected in the Sampler or Estimator query. However, if a job has fewer than 10,000 two-qubit gates, it will pass validation. Some options might allow more, and the service will calculate the limit allowed for the user-selected options and communicate that should your job be rejected in validation.
