Homomorphic Logical Measurements in Quantum LDPC Codes

Watch a technical seminar from the Qiskit Seminar Series featuring Shilin Huang discussing homomorphic logical measurements in quantum computing. Explore the evolution of quantum low-density-parity-check (LDPC) codes as promising candidates for fault-tolerant quantum storage and computation. Learn about existing methods for logical measurements on small quantum codes, including Shor and Steane methods, and discover how homomorphic measurements provide a unified framework that overcomes traditional limitations. Examine practical applications through hyperbolic surface codes, connecting fault-tolerant logical operation design with algebraic topology's theory of covering spaces. Presented by Shilin Huang, an incoming postdoc at Yale University and former IBM research intern, this 70-minute presentation includes detailed slides and explores cutting-edge developments in quantum computing architecture and information manipulation.
