Benchmarking NISQ Devices Using qFlex

Quantum supremacy is the task to perform a quantum calculation on a Noisy-Intermediate Scale Quantum (NISQ) device that cannot be performed on the latest and most powerful supercomputer by using the best known classical simulator. To this end, the Google team has designed a series of benchmarks, based on the sampling of Random Quantum Circuits (RQCs), to challenge classical supercomputers. In a programming-like language, the RQC sampling corresponds to the first “Hello, World!” program in the quantum computing era. In my talk I will present qFlex, a fast and flexible software to simulate large RQCs to both verify and benchmark NISQ devices. qFlex is a NASA-Google-ORNL collaboration and it's now publicity available at https://github.com/ngnrsaa/qFlex. As part of my talk, I will show some live demos and present our latest results on benchmarking available NISQ devices.
