def u3(theta: float, phi: float, lam: float, qubit: Qubit)

Public import paths

• from bloqade.squin import u3
• from bloqade.squin.stdlib.simple import u3

Apply the U3 gate of a qubit.

The applied gate is represented by the unitary matrix given by:

$U3(\theta, \phi, \lambda) = R_z(\phi)R_y(\theta)R_z(\lambda)$

Parameters

Name	Type	Description
theta	float	Rotation around Y axis (radians).
phi	float	Global phase shift component (radians).
lam	float	Z rotations in decomposition (radians).
qubit	Qubit	Target qubit.
