Quantum information compression differs from classical methods. The study shows optimal quantum compression rates vary based on faithfulness, revealing an incompressible quantum data component.

Area of Science:

  • Quantum Information Theory
  • Quantum Computing
  • Information Theory

Background:

  • Classical random variables are faithfully compressed to within one bit of Shannon entropy.
  • Quantum sources produce mixed states, posing unique compression challenges.

Purpose of the Study:

  • Generalize classical variable-length compression to quantum sources.
  • Investigate compression rate differences between optimal and fixed-length scenarios for quantum states.

Main Methods:

  • Analysis of variable-length and fixed-length compression for quantum sources.
  • Comparison of compression rates in the limit of large block lengths.

Main Results:

  • Optimal quantum compression rate differs from the fixed-length, asymptotically faithful scenario.
