Return a list of the qubits for which the given instruction is defined. Single qubit instructions return a flat list, and multiqubit instructions return a list of ordered tuples.
Instruction]) – The name of the circuit instruction.
- Return type
Qubit indices which have the given instruction defined. This is a list of tuples if the instruction has an arity greater than 1, or a flat list of ints otherwise.
PulseError – If the instruction is not found.
