Numerical simulation of D-Wave's quantum advantage experiment with time-dependent variational Monte Carlo
A new arXiv preprint applies time-dependent variational Monte Carlo to simulate the D-Wave quantum advantage experiment reported by King et al. The abstract notes that King et al. had argued classical simulation would require exponential resources for tensor networks and neural quantum states, and frames this work as a test of that claim. The available abstract ends before revealing the simulation's outcome.

If the t-VMC results hold up, this method could become a standard classical benchmark for future quantum annealing advantage claims, allowing rapid independent checks before such claims are widely accepted.
The preprint targets the specific experiment already used to assert quantum advantage. If it reproduces the annealer dynamics on the same graphs, other groups can apply the method to new D-Wave results; the necessary code and methods are emerging now, so adoption could happen within two years.
