Performances of Block Codes Attaining the Expurgated and Cutoff Rate Lower Bounds on the Error Exponent of Binary Classical-Quantum Channels
Pawel Wocjan, Dejan E. Lazic, Thomas Beth
A conceptually simple method for derivation of lower bounds on the error exponent of specific families of block codes used on classical-quantum channels with arbitrary signal state…

The thermodynamic cost of reliability and low temperatures: Tightening Landauer's principle and the Second Law
Dominik Janzing, Pawel Wocjan, Robert Zeier +2
Landauer's principle states that the erasure of one bit of information requires the free energy kT ln 2. We argue that the reliability of the bit erasure process is bounded by the…
