Zero-noise extrapolation is a technique used in quantum computing to reduce the impact of noise on quantum computations by extrapolating results obtained at different noise levels to estimate the ideal result at zero noise. This method is particularly relevant in variational algorithms, where the presence of noise can significantly affect the accuracy of computed results. By analyzing the effects of noise and systematically reducing it through extrapolation, this approach enhances the reliability of quantum computations, particularly in methods like the Variational Quantum Eigensolver.
congrats on reading the definition of zero-noise extrapolation. now let's actually learn it.
