Day 675: Syndrome Decoding

Day 675 of 2,016~17 min read

Learning Objectives

  • •Define and compute the syndrome of a received word
  • •Explain why syndrome decoding is information-preserving (critical for quantum!)
  • •Construct syndrome lookup tables for error correction
  • •Understand cosets and the standard array
  • •Implement maximum-likelihood decoding via syndromes
  • •Analyze the computational complexity of decoding
