Squeezing Quantum Information through a Classical Channel: Measuring the "Quantumness" of a Set of Quantum States
Christopher A. Fuchs, Masahide Sasaki
In this paper we propose a general method to quantify how "quantum" a set of quantum states is. The idea is to gauge the quantumness of the set by the worst-case difficulty of tran…

Information Rates Achievable with Algebraic Codes on Quantum Discrete Memoryless Channels
Mitsuru Hamada
The highest information rate at which quantum error-correction schemes work reliably on a channel, which is called the quantum capacity, is proven to be lower bounded by the limit…
