Explore quantum low-density parity-check (qLDPC) codes in this recorded lecture from IPAM's Winter School on Quantum Error Suppression, Mediation, and Correction at UCLA. Professor Yufei Ding from the University of California, San Diego delivers an in-depth presentation examining the principles and applications of qLDPC codes in quantum error correction. Delivered in February 2025, the 94-minute talk serves as a comprehensive introduction to this crucial aspect of quantum computing, focusing on error suppression and mitigation techniques. Gain valuable insights into the theoretical foundations and practical implementations of quantum error-correcting codes that are essential for building reliable quantum computing systems.
