Researchers at Swinburne University of Technology have developed a fast new way to check whether certain quantum computers, specifically Gaussian Boson Samplers, are actually producing the results they claim, without waiting millennia for a supercomputer to verify them.
Their method can flag errors in minutes on an ordinary laptop, revealing unexpected noise in a recent experiment that would otherwise take 9,000 years to validate.
This new study addresses a core paradox: if quantum computing is solving problems that cannot be checked by conventional methods, how can we be certain the results are correct? Read more →
