Quantum error mitigation is crucial for us to protect quantum computing against quantum errors before quantum error correction is truly available, which is still one or two decades away. Though some error mitigation protocols, like error extrapolation and error cancellation, have been demonstrated successfully in experiments using small scale quantum systems, whether they behave well on large s...
AbstractIn this talk, some well known literatures about approximation error of operator learning will be reviewed and discussed. Especially, application of specific PDE by this approximation analysis will be presented
