Gram-Certified Resource Continuation for Structured Quantum Representation Audits

Azadeh Alavi, Fatemeh Kouchmeshki, Hossein Akhoundi +1

Dense representation of an -qubit pure state requires complex amplitudes, precluding dense classical materialization at large . We develop Gram-certified resource conti…

Invariance Audits for Quantum Kernels and Variational Rewinding: A Real-to-Hermitian Taxonomy of Projector, Flag, Anchor, and Density Geometry

Azadeh Alavi, Fatemeh Kouchmeshki, Hossein Akhoundi

Machine-learning models often replace vectors by normalized directions, projectors, covariances, subspaces, ordered flags, quantum states, or density operators before any classifie…

HamQASBench: A Hamiltonian-Informed Diagnostic Benchmark for Evaluating Quantum Architecture Search

Jiayang Niu, Akib Karim, Yan Wang +5

Quantum Architecture Search (QAS) automates the design of parameterized quantum circuits for variational quantum algorithms, yet existing benchmarks organize instances by molecular…

Quantum Semi-Random Forests for Qubit-Efficient Recommender Systems

Azadeh Alavi, Fatemeh Kouchmeshki, Abdolrahman Alavi +2

Modern recommenders describe each item with hundreds of sparse semantic tags, yet most quantum pipelines still map one qubit per tag, demanding well beyond one hundred qubits, far…

A Geometric-Aware Perspective and Beyond: Hybrid Quantum-Classical Machine Learning Methods

Azadeh Alavia, Hossein Akhoundib, Fatemeh Kouchmeshkib +4

Geometric Machine Learning (GML) has shown that respecting non-Euclidean geometry in data spaces can significantly improve performance over naive Euclidean assumptions. In parallel…
