bloqade.qasm2.cu

Signature

def cu(ctrl: Qubit, qarg: Qubit, theta: float, phi: float, lam: float, gamma: float) -> None

Controlled 4-parameter unitary gate.

This is equal to:

gate cu(theta,phi,lambda,gamma) c, t{ p(gamma) c; p((lambda+phi)/2) c; p((lambda-phi)/2) t; cx c,t; u(-theta/2,0,-(phi+lambda)/2) t; cx c,t; u(theta/2,phi,0) t; }

Parameters

Name	Type	Description
ctrl	Qubit	The control qubit.
qarg	Qubit	The target qubit.
theta	float	The angle of rotation.
phi	float	The angle of rotation.
lam	float	The angle of rotation.
gamma	float	The angle of rotation.
