 Quantum computers are very sensitive to noise, disturbances that cause errors in their computations. But new research shows IBM's noisy quantum computers matching exact classical methods and verifiable regimes, and outperforming sophisticated classical approximation methods in both verifiable and under-verifiable regimes for a challenging simulation experiment. How do they do this? They use the special technique for dealing with the noise in quantum systems. It's called error mitigation. With the error mitigation technique used in this experiment, we run our calculations and slowly turn the noise up. Then we extrapolate back to the noise-free solution. This work brings us one step closer to useful quantum computing.
