# FermionicSpecifier

### FermionicSpecifier *: [TypeAlias](https://docs.python.org/3/library/typing.html#typing.TypeAlias)* *= qiskit.circuit.Qubit | qiskit.circuit.QuantumRegister | int | slice | collections.abc.Sequence[qiskit.circuit.Qubit | int]*

A type alias equivalent to Qiskit’s `QubitSpecifier` but for fermionic modes.
