I'm trying to use Qiskit's built in transpiler passes to do the following. I would like to take a quantum circuit and allocate the logical qubits to physical qubits.
The tutorial doesn't really explain how to do this. I would like to use one of the preset passes (
DenseLayout, etc) to get this allocation.
from qiskit import QuantumCircuit from qiskit.compiler import transpile from qiskit.transpiler import PassManager, passes from qiskit.test.mock import FakeMelbourne # NB will need to install dev requirements """ This is the circuit we are going to look at""" qc = QuantumCircuit(13, 13) qc.h(3) qc.cx(0,6) qc.h(1) qc.cx(6,0) qc.cx(0,1) qc.cx(3,1) qc.h(3) qc.cx(3,0) qc.measure_all() backend = FakeMelbourne() properties = backend.properties() coupling_map = backend.configuration().coupling_map
The output of the program should be a dictionary or something that gives tells me which physical qubit each logical qubit is mapped to. How can I do this?
