D-Wave Simulation Quality Would Take 1 Million Years on Frontier Supercomputer

A simulation performed by D-Wave’s quantum processing unit would take nearly a million years to replicate on the Frontier supercomputer, according to results published in Science and now reaffirmed by D-Wave Quantum Inc. The company is responding to claims that recent classical simulation work has invalidated its demonstration of beyond-classical computation in quantum simulation. Researchers at the Flatiron Institute have made progress with their BP-TNS algorithm, adding large diamond lattice data to their simulations, but this work falls short of fully replicating D-Wave’s original experiment, failing to compute the same observables, geometries, sizes, or couplings. “These are important cases from…
