Fourier-Geometric Circuit Design for Gate and Entanglement Placement in Quantum Neural Networks
Seungcheol Oh, Chaemoon Im, Daeyeun Kim +4
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…

Query Learning Nearly Pauli Sparse Unitaries in Diamond Distance
Zahra Honjani, Mohsen Heidari
We study the problem of learning nearly -sparse unitaries, meaning that the Pauli spectrum is concentrated on at most components with at most residual mass in Pauli…

Accelerating Feedback-based Algorithms for Quantum Optimization Using Gradient Descent
Masih Mozakka, Mohsen Heidari
Feedback-based methods have gained significant attention as an alternative training paradigm for the Quantum Approximate Optimization Algorithm (QAOA) in solving combinatorial opti…
