Composing Quantum Computing Controls

The QBN we’re going to build will consist of some advanced transformation gates. Let’s look at how we can create such gates.

Quantum transformation gates allow us to work with qubits. The $R_Y$-gate enables us to specify the qubit state vector angle $\theta$ that controls the probability of measuring the qubit as either 0 or 1. We used it to let a qubit represent the marginal probability of surviving the Titanic shipwreck.
