IBM has published details on a collection of techniques it hopes will usher in quantum advantage, the inflection point at which the utility of quantum computers exceeds that of traditional machines. The focus is on a process known as error mitigation, which is designed to improve the consistency and reliability of circuits running on quantum processors by eliminating sources of noise.  IBM says that advances in error mitigation will allow quantum computers to scale steadily in performance, in a similar pattern exhibited over the years in the field of classical computing.
