bloch_vector_to_standard_basis

forest.benchmarking.utils.bloch_vector_to_standard_basis(theta: float, phi: float) → Tuple[complex, complex]

Converts the Bloch vector representation of a 1q state given in spherical coordinates to the standard representation of that state in the computational basis.

Parameters:

• theta – azimuthal angle given in radians
• phi – polar angle given in radians

Returns:

tuple of the two coefficients a and b for the state a|0> + b|1> where a is real
