U3Gate.calc_params

U3Gate.calc_params(utry)[source]

Calculate the three parameters to a U3Gate from a given unitary.

Parameters:

utry (UnitaryMatrix) – The single-qubit unitary matrix to calculate a U3Gate’s parameters for.

Returns:

The three parameters to a U3Gate,: such that, U3Gate().get_unitary will return utry.

Return type:

list[float]

Raises:

ValueError – If utry is not a single-qubit unitary.
