FermionicGate

class FermionicGate(name, num_modes, params=None, label=None, generator=None)

Unitary gates for fermionic circuits.

Parameters:

• name (str) – The Qobj name of the gate.

• num_modes (int) – The number of fermionic modes the gate acts on.

• params (Optional[List]) – A list of parameters.

• label (Optional[str]) – An optional label for the gate.

• generator (Optional[FermionicOp]) – The generating Hamiltonian of the gate unitary given as a FermionicOp
