Combating quantum noise with AWS: University of Washington Capstone Project

This article describes a University of Washington capstone project sponsored by AWS that created a laboratory for combating quantum noise through three complementary strategies.

• Characterized qubit decay using T1 and T2 coherence times and applied dynamical decoupling on Rigetti Cepheus-1 QPU via Amazon Braket
• Implemented zero-noise extrapolation (ZNE) using AWS Batch to parallelize circuit variants on noisy simulators
• Simulated quantum error correction codes using AWS PCS with Stim and PyMatching libraries for scaled computation
• Demonstrated end-to-end workflow mapping noise suppression, mitigation, and correction to respective AWS services
• Provided open-source notebooks and CloudFormation templates for researchers to replicate the infrastructure

The project shows how AWS services naturally scale quantum noise research from hardware-level suppression through post-processing mitigation to fault-tolerant error correction.
