braket_ahs simulator readout noise

[masaduzz1]

Hi, in the braket_ahs simulator, I see some discrepancy of the average density with respect to the results obtained from my exact diagonalization code. The discrepancy is greater for cases with more atoms. This made me think if there is a readout error already incorporated in the results of the braket_ahs simulator? I could not find relevant discussion on the simulator in the AWS page: https://docs.aws.amazon.com/braket/latest/developerguide/braket-submit-tasks-simulators.html#braket-simulator-ahs-local. Any comment in this regard will be much appreicated. --Asad, postdoc @ UIowa.
