Researchers from the Flatiron Institute and Boston University, supported by the Simons Foundation, have cast doubt on D-Wave’s claims of quantum supremacy.<\/p>\n
On May 21, a paper<\/a> was published in Science, asserting that some problems previously deemed unsolvable by classical computers can indeed be tackled using traditional methods.<\/p>\n In an accompanying statement<\/a>, the Simons Foundation noted that earlier claims of quantum supremacy are now “in question.”<\/p>\n The discussion revolves around a D-Wave article<\/a> published last year in the same journal. At that time, the company claimed its system had performed quantum dynamics simulations beyond the reach of classical algorithms. According to D-Wave, the largest configurations would have required the Frontier supercomputer nearly a million years to compute.<\/p>\n This assertion is now being challenged.<\/p>\n The Flatiron team employed a combination of tensor networks and a modified belief propagation algorithm. The researchers claimed they were able to reproduce calculations for several lattices using standard equipment\u2014some experiments were even conducted on a laptop.<\/p>\n The conclusion: at least some tasks presented as demonstrations of quantum supremacy are not beyond the reach of classical computing.<\/p>\n D-Wave disagreed<\/a>. On May 26, the company acknowledged the progress of classical methods but stated that the researchers only tested limited modes and did not replicate the full set of problems from the original work. According to the firm, the new paper does not cover the entire range of geometries, system sizes, interaction parameters, and measurable quantities.<\/p>\n The debate extends beyond academic circles. On June 1, D-Wave will hold an Investor Day at the NYSE, where it promises to present its strategy, roadmap, and commercial prospects. CEO Alan Baratz stated that the industry is entering a phase of proven results rather than promises.<\/p>\nThe Core of the Dispute<\/h2>\n
