In Qiskit, there are many different Quantum Error Functions.
From my understanding,
pauli_error represents the error rate of $X, Y, Z$ independently, and
deplolarizing_error is a combination of these Pauli operators. Is it correct? Are the two channels belong to incoherent errors?
amplitude_damping_error be regarded as $Z$ and $X$ errors respectively? Are they coherent or incoherent errors?
