Practical Quantum Computing with D-Wave
summary
Demo shows D-Wave Leap 2 running a knapsack and returning a solution via the cloud; hybrid solver gives up to 10 minutes free and the 2000Q device has ~2,000 qubits and ~6,000 couplers. Hybrid solver handles problems up to 10,000 fully connected variables; the open source dwave-hybrid framework implements decomposition, roof duality preprocessing, QPU-seeded tabu postprocessing and qboost meta-algorithms (co-developed with Google) and the racing trick compares QPU and local solvers to pick the best result.
