How to find expressible and trainable parameterized quantum circuits?
Peter Röseler, Dennis Willsch, Kristel Michielsen
Whether parameterized quantum circuits (PQCs) can be systematically constructed to be both trainable and expressive remains an open question. Highly expressive PQCs often exhibit b…
Exposing Finite-Depth, Finite-Shot Guarantees for Constrained Quantum Optimization via Fejér Filtering
Chinonso Onah, Kristel Michielsen
Constrained quantum optimization algorithms need quantitative guarantees that connect circuit resources to the probability of actually sampling feasible or optimal solutions in fin…
Interplay of Confinement and Localization in a Programmable Rydberg Atom Chain
Andrea B. Rava, Jhon A. Montanez-Barrera, Kristel Michielsen +1
Analog quantum simulators promise access to complex many-body dynamics, yet their performance is ultimately set by how device imperfections compete with intrinsic physical mechanis…
Benchmarking neutral atom-based quantum processors at scale
Andrea B. Rava, Kristel Michielsen, J. A. Montanez-Barrera
In recent years, neutral atom-based quantum computation has been established as a competing alternative for the realization of fault-tolerant quantum computation. However, as with…
Fundamental Limitations of QAOA on Constrained Problems and a Route to Exponential Enhancement
Chinonso Onah, Kristel Michielsen
We study fundamental limitations of the generic Quantum Approximate Optimization Algorithm (QAOA) on constrained problems where valid solutions form a low dimensional manifold insi…
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,…
