Description

Qiskit has uniformly controlled gates (AKA multiplexors) https://docs.quantum.ibm.com/api/qiskit/qiskit.circuit.library.UCGate

It should be possible to convert these operations to a MultiplexorBox and the other types of Multiplexor supported in TKET.

I guess its a question of whether this is a useful enough conversion to be worth implementing and maintaining.

Contributor guide

Research direction
Study the existing conversion logic in pytket qiskit for other gate types, and understand how UCGate is defined in Qiskit and how MultiplexorBox works in pytket. Consider implementing the conversion and adding tests.
