Inaccurate fitted amplitude in rabi_amplitude_msr

aorgazf opened this issue · comments

Hi,
I've noticed that the fit of the amplitude of the pi pulse in rabi_amplitude_msr returns a value that is close, but incorrect.

As you may see in the picture, the returned value is 0.436, but the argmax of the fitting curve is 0.466.
I've tried it on several qubits and it always gives a slightly smaller value.

Hi @aorgazf,
thanks for opening the issue.
From the report it seems that you are using an older version of the code.
Do you see the same bug with the latest version of the code?

Hi @andrea-pasquale, I believe the issue is still there:
