quri_parts.circuit.clifford_gate module#
- is_clifford(gate, rtol=1e-05, atol=1e-08)#
Returns True if the input gate is Clifford, otherwise False. In the case of a rotation gate, whether it is a Clifford gate or not is determined by whether the rotation angle is in the Clifford angle set
or not. This can be applied only to the gates in the set CLIFFORD_GATE_NAMES and currently implemented rotation gates: {RX, RY, RZ, U1, U2, U3, PauliRotation}. Since newly defined gates (e.g. U’(a, b) = RZ(2*a)RY(a+2b)) may return the wrong result, in this case this function currently returns a NotImplementedError.- Parameters:
gate (QuantumGate) – A gate to be checked whether Clifford or not.
rtol (float) – The relative tolerance parameter determines how close the angle of rotation is to the angle in the Clifford angle set.
atol (float) – The absolute tolerance parameter determines how close the angle of rotation is to the angle in the Clifford angle set.
- Return type:
bool
