Overview
Watch a 25-minute conference talk from TQC 2023 (Theory of Quantum Computation Conference) exploring a breakthrough solution for scalable fault-tolerant quantum computation through parallel window decoding. Learn how this novel approach addresses the critical data backlog problem in Quantum Error Correction (QEC) that currently limits quantum computing scalability. Discover the technical implementation of parallelized decoding that achieves nearly unlimited speed while maintaining logical fidelity, requiring only polynomial slowdown in code size rather than exponential. Delve into detailed numerical demonstrations using surface code, understanding how this advancement could help realize large-scale quantum computers capable of reliable fault-tolerant computations. The presentation, delivered at the University of Aveiro as part of the 18th TQC conference, covers introduction to sliding window decoding and hardware implementation aspects, supported by research published on arXiv.
