Is there any built-in functions in Qiskit to help with two qubit gate decomposition? Thanks in advance!

Hi there, just want to clarify the post. Are you trying to decompose some arbitrary 2-qubit unitary operation into some basis gates? If so, u might find the following useful:

qiskit.org/documentation/stubs/qiskit.quantum_info.TwoQubitBasisDecomposer.html

FYI, u might also want to understand how to construct a universal 2-qubit gate [1]. The conclusion is we need at least 15 single qubit rotation gates from ${ R_y, R_z }$ and 3 CNOT gates.
