How to implement IBM AAIS on IBM devices

One can easily translate instruction calls of AAIS into single qubit and two qubit rotation gates in Qiskit.

Since the compiled abstract schedule may contain a large amount of short evolution fragments, the Qiskit compiler makes use of two CNOT gates to realize one rotation gate because of calibration convenience. We make use of the pulse-efficient circuit transpilation to shorten the total duration of generated pulse
