Math 401, Paper 1, Side note 1: Quantum information theory and Measure concentration

Shannon theory provides a way to quantify the amount of information in a message.

Practically speaking:

• A holy grail for error-correcting codes
• Conceptually speaking:
• An operationally-motivated way of thinking about correlations
• What’s missing (for a quantum mechanic)?
  • Features from linear structure:
    • Entanglement and non-orthogonality
