Researchers at the University of Waterloo have developed a method that could reach to establishing universal standards for measuring the performance of quantum computers. The new method, called cycle benchmarking, allows to assess the potential of scalability and to compare one quantum platform against another, which is especially important as vendors struggle to claim quantum supremacy.
This method determines the total probability of error under any given quantum computing applications when the application is implemented through randomized compiling. This means that cycle benchmarking provides the first cross-platform means of measuring and comparing the capabilities of quantum processors that is customized to users’ applications of interest.
