Benchmarking the ORCA PT-2 Boson Sampler using Minimum Dominating Set Problems
Jessica Park, Susan Stepney, Irene D'Amico
We use boson sampling as part of a gradient-free variational algorithm (the Binary Bosonic Solver) to solve a minimum dominating set problem and compare these results to a number o…
Benchmarking ORCA PT-1 Boson Sampler in Simulation
Jessica Park, Susan Stepney, Irene D'Amico
Boson Sampling, a non-universal computing paradigm, has resulted in impressive claims of quantum supremacy. ORCA Computing have developed a time-bin interferometer (TBI) that claim…
A methodology for comparing and benchmarking quantum devices
Jessica Park, Susan Stepney, Irene D'Amico
Quantum Computing (QC) is undergoing a high rate of development, investment and research devoted to its improvement.However, there is little consensus in the industry and wider lit…
An analysis of the relative effects of connectivity and coupling interactions on spin networks emulating the D-Wave 2000Q quantum annealer
Jessica Park, Susan Stepney, Irene D'Amico
From available data, we show strong positive spatial correlations in the qubits of a D-Wave 2000Q quantum annealing chip that are connected to qubits outside their own unit cell. T…
