C2QA Quantum Thursdays

"Closing the Gap between Quantum Algorithms and Hardware using Compilation and Architecture"

Presented by Margaret Martonosi, Princeton University

Thursday, February 3, 2022, 12:00 pm — Videoconference / Virtual Event (see link below)

In recent years, QC hardware has progressed considerably with small systems being prototyped by industry and academic vendors. However, there is a huge gap between the resource requirements of promising applications and the hardware that is buildable now. Qubit counts and operational noise constraints of applications exceed hardware capabilities by 5-6 orders of magnitude. Our work seeks to enable practical QC by bridging this gap: from the top with novel compiler techniques and algorithmic optimizations to reduce application requirements and from the bottom via system architectures efficiently exploiting scarce QC resources. This talk will present several of the cross-cutting optimizations we have proposed and evaluated to narrow the applications-to-hardware resource gap. These include noise-adaptive compilation techniques, and novel methods for gate selection and application tailoring. In response to our work, several industry vendors have included our techniques in their approaches.
