Workshop:FTXS: Workshop on Fault-Tolerance for HPC at Extreme Scale
Authors: Devesh Tiwari (Northeastern University)
Abstract: Quantum computing has moved from theoretical promise to practical realization -- at a very rapid pace in the last decade. But, prohibitively high error rates on existing Near-term Intermediate-Scale Quantum (NISQ) computers limit their usability even for quantum-advantage-proven algorithms (that is, algorithms that are infeasible or orders of magnitude slower on classical computers). As a result, the executions of these algorithms on existing quantum computers are highly erroneous and produce program output that can be far from the correct output. In this talk, first, I will provide an overview of the reliability challenges in quantum computing systems. Then, I'll discuss novel approaches toward estimating the correct program output on erroneous quantum devices.
