Fourier-Geometric Circuit Design for Gate and Entanglement Placement in Quantum Neural Networks
The output of a parameterized quantum circuit (PQC) can be expressed as a finite Fourier series whose accessible frequencies are fixed by the data-encoding gates. While the encoder determines which frequencies can appear, the corresponding Fourier coefficients depend on how the trainable and entangling gates are arrang...
