D-Wave says quantum supremacy result stands; Flatiron work does not reproduce hardest cases
--------------------------------------------------------------------------------

- Company states recent classical simulation work from Flatiron Institute does not overturn its peer-reviewed Science result.
- CEO Alan Baratz says full scope of demonstration, including hardest cases and measurements, has not been reproduced.
- CDO Trevor Lanting notes BP-TNS algorithm fails for strongly coupled 3D spin glasses and biclique problems.
- Original Science paper showed matching quantum simulation quality would require nearly 1M years on Frontier supercomputer.
- D-Wave encourages classical progress but distinguishes meaningful advance from overturning a quantum supremacy claim.
