CU1 gate cannot be printed to qasm #233

Open bachbao opened 3 months ago

It occurs to me that when using ControlledGate(U1Gate()), the feature to output qasm file is having issue.

Thanks for making this bug report. To clarify, we should be able to build a ControlledGate(U1Gate()) and save to qasm, load that same qasm, and have the same gate.

from bqskit.ir.gates import ControlledGate, U1Gate
g = ControlledGate(U1Gate())

from bqskit import Circuit
c = Circuit(2)
c.append_gate(g, (0, 1))
c.to('qasm')

This seems to be printing fine. @bachbao, do you have a case where this isn't working?
