qrisp.QuantumCircuit.u3#

QuantumCircuit.u3(theta, phi, lam, qubits)[source]#

Instruct a U3-gate from given Euler angles.

A U3 gate has the unitary:

$$\begin{array}{r}U3(\theta ,\varphi ,\lambda )=\left(\begin{array}{cc}\cos (\frac{\theta }{2})& -\exp (i\lambda )\sin (\frac{\theta }{2})\\ \exp (i\varphi )\sin (\frac{\theta }{2})& \exp (i(\varphi +\lambda ))\cos (\frac{\theta }{2})\end{array}\right)\end{array}$$

Parameters:

thetafloat or sympy.Symbol

The theta parameter.

phifloat or sympy.Symbol

The phi parameter.

lamfloat or sympy.Symbol

The lambda parameter.

qubitsQubit

The Qubit to apply the u3 gate on.
