Parametric Gates

Explore how parametric gates allow customizable rotations of qubits on the Bloch Sphere by controlling parameters like phi. Understand the roles of Rz, Rx, and Ry gates in variational algorithms and their relation to standard gates such as Z, S, and T gates. This lesson helps you grasp how these gates add flexibility to quantum circuit operations.

We'll cover the following...

- The $\space R_\phi \space$ gate
- The $\space R_x\space$ and $\space R_y\space$ gates

We’ve introduced you to the basic single qubit and multi-qubit gates that are widely used while working on quantum algorithms. However, those gates always perform a fixed operation or a fixed rotation around one of the axes of the Bloch Sphere. What if we wanted to change the state of a qubit to any state of our choice or, perform a rotation on the Bloch Sphere using some arbitrary value? This is where parametric gates come in. Such gates come in handy while working on variational quantum algorithms.
