Connectome-Based Modeling of Mutation-Specific Amyloid- Aggregation in Familial Alzheimer's Disease
Mohammad Alamgir Chowdhury, Hina Shaheen
Familial amyloid- (A) variants alter aggregation kinetics, but their interaction with structural brain connectivity remains incompletely understood. We developed a mutation-a…
Complexity Barriers to State Preparation in Quantum Approximate Optimization
Stuart Hadfield
For many important optimization problems we are restricted to approximate solutions in practice due to computational complexity. Distinct from the exact optimization setting, appro…
Complexity Amplification from Compression in Quantum Random Access Optimization
Stuart Hadfield
Compressed quantum encodings aim to overcome hardware limitations towards tackling challenging problems at scale, with many classical variables mapped onto noncommuting observables…
No Free Compression in Quantum Relaxations for Optimization
Stuart Hadfield
Qubit-efficient quantum relaxations compress classical decision variables into expectation values on substantially fewer qubits. We ask what resource tradeoffs this compression ent…
Separating Geometry From Interference in Constrained Quantum Optimization
Chinonso Onah, Stuart Hadfield, Kristel Michielsen
We study the separation of geometric effects from quantum interference in quantum optimization algorithms. Constrained optimization problems such as routing, assignment, and schedu…
Evaluating QAOA expectation values can be as hard as counting optimal solutions
Stuart Hadfield
Evaluating expectation values is a critical task for variational quantum eigensolvers, parameterized quantum circuits, and many other quantum algorithms. We consider the well-studi…
