A cross-platform study of near-term quantum optimisation algorithms on the graphene defect problem

Quantum computers show potential for achieving computational advantage over classical computers, with many candidate applications in combinatorial optimisation. We present a focussed, application-level hardware case study of near-term quantum optimisation algorithms applied to a dense quadratic unconstrained binary opt...

Scaling Quantum Optimization to the Thousand-Qubit Scale with Distributed Quantum Sampling

The Minimum Birkhoff Decomposition (MBD) seeks a sparse weighted sum of matchings and is a challenging optimization problem with applications in network scheduling and energy trading. We scale a quantum-assisted decomposition method by combining single-layer QAOA sampling with Extended Fully-Corrective Frank-Wolfe (E-F...
