Evaluating Sample-Based Krylov Quantum Diagonalization for Heisenberg Models with Applications to Materials Science
Roman Firt, Neel Misciasci, Jonathan E. Mueller +4
We evaluate the Sample-based Krylov Quantum Diagonalization (SKQD) algorithm on one- and two-dimensional Heisenberg models, including strongly correlated regimes in which the groun…

Empirical Quantum Advantage in Constrained Optimization from Encoded Unitary Designs
Chinonso Onah, Roman Firt, Kristel Michielsen
We introduce the Constraint-Enhanced Quantum Approximate Optimization Algorithm (CE-QAOA), a shallow, constraint-aware ansatz that operates inside the one-hot product space [n]^m,…
