Zero-operand gates and instructions will now work with
|
|
:func:`.circuit_to_gate`, :meth:`.QuantumCircuit.to_gate`,
|
|
:meth:`.Gate.control`, and the construction of an
|
|
:class:`~.quantum_info.Operator` from a :class:`.QuantumCircuit` containing
|
|
zero-operand instructions. This edge case is occasionally useful in creating
|
|
global-phase gates as part of larger compound instructions, though for many
|
|
uses, :attr:`.QuantumCircuit.global_phase` may be more appropriate.
