I have something problem with using qiskit. I searched several qiskit docs to get 'qubit location' or 'variables' that represent qubit.
I searched three documents below.
qiskit.transpiler.passes.layout.sabre_layout qiskit.transpiler.passes.routing.sabre_swap qiskit.dagcircuit.DAGCircuit
However, I couldn't get the information about qubit location in these docs. SABRE algorithm use qubit location to switch qubit's location to execute on the real quantum hardware with satisfying its coupling graph. That's why I'm sure that these docs will contain information about qubit location to use them. But I can't find it. Could you help me?
If I need to find out some other docs, please let me know. Thank you.
