Something’s off.IBM’s Nighthawk r2 reportedly generated one million samples in nineteen seconds using sixty-one qubits and a thirty-six-cycle random circuit. The experiment used a cloud-accessible quantum processor.
The strange comparison is not the sampling itself, but the reported estimate for reproducing those results conventionally: the researchers calculated about 1.2 × 10²⁷ operations, or roughly 110 years on a supercomputer under their assumptions. That estimate comes from a tensor-network simulation method, rather than from running the task on a supercomputer.
The researchers say their result does not establish a permanent limit for classical computing. A more efficient classical algorithm could reduce the estimate, and the underlying work is currently available as a preprint rather than a peer-reviewed paper.
