AASRouting doesn't work for circuits with non-default register names. #1534
Description
Benny and I found this by running a randomly generated circuit through the compiler
subcirc_4 = Circuit(2, 2, "subcirc_4")
subcirc_4.add_q_register("qreg", 1)
subcirc_4.measure_all()
AASRouting(RingArch(subcirc_4.n_qubits)).apply(subcirc_4)Results in:
----> 7 AASRouting(RingArch(subcirc_4.n_qubits)).apply(subcirc_4)
9 draw(subcirc_4)
RuntimeError: Circuit does not contain unit with id: q[2]
