qiskit.ignis.verification.CNOTDihedral.compose

CNOTDihedral.compose(other, qargs=None, front=False)

Return the composed operator.

Parameters

• other (CNOTDihedral) – an operator object.

• qargs (None) – using specific qargs is not implemented for this operator.

• front (bool) – if True compose using right operator multiplication, instead of left multiplication [default: False].

Returns

The operator self @ other.

Return type

CNOTDihedral

Raises

• QiskitError – if operators have incompatible dimensions for composition.

• NotImplementedError – if qargs is not None.

Additional Information:

Composition (@) is defined as left matrix multiplication for matrix operators. That is that A @ B is equal to B * A. Setting front=True returns right matrix multiplication A * B and is equivalent to the dot() method.
