I want to run a simulation using
qasm with a realistic noise model from a backend, specifying a
coupling_map as well as an
initial_layout. I do that via a
QuantumInstance which in turn is passed to an algorithm. Now, two questions regarding that qubit layout:
I know that the transpiler may change the mapping of logical to physical qubits. Furthermore, I pass a circuit to the algorithm as an argument and the algorithm then adds an ancilla qubit to the circuit. Is there a way for me to verify the final logical to physical qubit mapping after transpiling?
Could that automatic adding of an ancilla cause problems when using
QuantumInstancewith a specific
