Before accepting these kind of PRs, one should check that the snapshot is actually a good one. Here some of the 2Q gates have errors of 1, eg.: ``` "qubits":...

So the difference is that Geneva is a new 27Q system that probably still has some kinks to work out. You are grabbing a snapshot of it when there are...

@jlapeyre Hmm, I think expectation value and average mean the same thing here. I guess your advocating for less physics orientated terminology? Even the Mike and Ike quote above does...

I do not think the operator and the state are on the same footing exactly. Namely it is the operator that determines much of the physical properties of the expectation...

I am also not a big fan of the `expectation(op, state)` way of doing things as it is a very Matlab way of doing things and does not leverage the...

The `Estimator` doesn't actually provide a unified interface. If all someone wanted was expectation values then yes. But what if I want to compute expectation values and also plot the...

I would also say that Qiskit is about more than the Runtime. Other hardware vendors might not implement the Runtime interfaces, and anyway the base implementations are statevector only. Thus...

So yeah when improving the `Estimator` your going to end up writing something like `counts.expectation_value` and then the request of this Issue is fulfilled, and others outside of Runtime can...

Bit-strings are the input to things like expectation values (see #8465) so it makes sense to have that data type returned as quickly as possible. So I guess the caching...

I see that the `QuasiDistribution` is looking for an upper bound on the standard deviation, whereas the IBM Runtime `Sampler` is returning the `mitigation_overhead`. One or the other should be...
