qit.utils.R_nmr

qit.utils.R_nmr(theta, phi)

SU(2) rotation \(\theta_\phi\) (NMR notation).

One-qubit rotation by angle theta about the unit vector \([\cos(\phi), \sin(\phi), 0]\), or \(\theta_\phi\) in the NMR notation.

Parameters

• theta (float) – rotation angle

• phi (float) – angle between the rotation axis and the positive x axis

Returns

rotation matrix

Return type

array[complex]
