Approximate Cosine Similarity Estimation via an Angle-Encoding Hadamard Test
Hiroshi Ohno
The Hadamard test is a standard quantum primitive for estimating inner products and expectation values, but in data-processing settings its practical utility is often limited by th…

Generalization analysis of quantum neural networks using dynamical Lie algebras
Hiroshi Ohno
The paper presents a generalization bound for quantum neural networks based on a dynamical Lie algebra. Using covering numbers derived from a dynamical Lie algebra, the Rademacher…
