Error suppression for quantum annealing and gate model NISQ devices

Presented by Daniel Lidar, University of Southern California

I will discuss our work on error suppression using the D-Wave, IBM, and Rigetti devices. For the D-Wave quantum annealer error suppression involves the use of repetition codes along with energy penalties to reduce the effective temperature and analog control errors. For the IBM and Rigetti chips we used dynamical decoupling. In both cases error suppression is a viable strategy resulting in actual performance improvements for these NISQ-era devices. Time permitting, I will discuss additional theoretical results on error suppression for Hamiltonian quantum computing involving more advanced encoding and schedule control than is possible using current devices.
