Next Big Future March 5, 2019
IBM has published a roadmap for improving quantum computers based on a “quantum volume” which is an architecture-neutral metric. It measures the useful amount of quantum computing done by a device in space and time. The results on the IBM Q System One indicate its performance is just over the threshold for 16. IBM roadmap is to double quantum volume every year. IBM wants to improve error rates 100 times from 1% to 0.01%. They plan to do this by increasing coherence times from 0.5 milliseconds to 1-5 milliseconds. The hope is to achieve quantum dominance before there is a need to shift to error-corrected quantum systems…read more.
