• D-Wave Quantum issued a response rejecting claims that new classical simulations overturned its quantum computational supremacy result in quantum simulation.
• It said the classical BP-TNS work did not reproduce the full scope of its peer-reviewed Science study or match the hardest instances.
• The company reiterated its largest cases would require nearly 1 million years on Frontier using matrix product state methods, with impractical memory and energy needs.
• It cited follow-up analysis saying BP-TNS fails on strongly coupled 3D spin glasses, with loop-corrected BP-TNS ineffective on higher-dimensional biclique problems.
