The passage around this formula
For a machine-learning task, the near-term architecture almost universally used is the parameterized (or variational) quantum circuit, and its mechanism has four concrete steps. First, classical input data x is encoded into a quantum state by applying a data-dependent unitary V(x) to a fixed initial state — commonly done by rotating each qubit by an angle set from one feature of x, so the input vector is literally written into rotation angles. Second, an “ansatz” unitary U(θ) — a fixed sequence of parameterized single-qubit rotation gates and two-qubit entangling gates, repeated over several layers — is applied, where θ is now a set of continuously adjustable classical numbers rather than…
