Abstract
This paper investigates the maximal channel coding rate achievable at a given blocklength and error probability. For general classes of channels new achievability and converse bounds are given, which are tighter than existing bounds for wide ranges of parameters of interest, and lead to tight approximations of the maximal achievable rate for blocklengths n as short as 100. It is also shown analytically that the maximal rate achievable with error probability ? isclosely approximated by C - ?(V/n) Q-1(?) where C is the capacity, V is a characteristic of the channel referred to as channel dispersion , and Q is the complementary Gaussian cumulative distribution function.

Entropy power inequalities for qudits

TL;DR: In this article, De Palma, Mari, and Giovannetti showed a quantum analogue of Shannon's entropy power inequality for continuous-variable quantum systems, where X and Y are replaced by bosonic fields and the addition rule is the action of a beam splitter with transmissivity a on those fields.

Tight Bound on Relative Entropy by Entropy Difference

TL;DR: A lower bound on the relative entropy between two finite-dimensional states is proved in terms of their entropy difference and the dimension of the underlying space, and the inequality is tight in the sense that equality can be attained for any prescribed value of the entropy difference.

Limits of low-probability-of-detection communication over a discrete memoryless channel

TL;DR: This paper considers the problem of communication over a discrete memoryless channel subject to the constraint that the probability that an adversary who observes the channel outputs can detect the communication is low.

Bayesian $M$ -Ary Hypothesis Testing: The Meta-Converse and Verdú-Han Bounds Are Tight

TL;DR: Two alternative exact characterizations of the minimum error probability of Bayesian M-ary hypothesis testing are derived and help to identify the steps where existing converse bounds are loose.

A mathematical theory of communication

TL;DR: This final installment of the paper considers the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now.
