Coding Theorems for Quantum Communication Channels
Let H be a Hilbert space providing a quantum-mechanical description for the physical carrier of information. A simple model of quantum communication channel consists of the input alphabet A = {1, ..., a} and a mapping i→ Si from the input alphabet to the set of quantum states in H. A quantum state is a density operator, i. e. positive operator S in H with unit trace, TrS = 1. Sending a letter i...
متن کاملSe p 19 98 Coding Theorems for Quantum Channels
– The more than thirty years old issue of the (classical) information capacity of quantum communication channels was dramatically clarified during the last years, when a number of direct quantum coding theorems was discovered. The present paper gives a self contained treatment of the subject, following as much in parallel as possible with classical information theory and, on the other side, str...
متن کاملCoding Theorems for Compound Problems via Quantum Rényi Divergences
We show two-sided bounds between the traditional quantum Rényi divergences and the new notion of Rényi divergences introduced recently in Müller-Lennert, Dupuis, Szehr, Fehr and Tomamichel, J. Math. Phys. 54, 122203, (2013), and Wilde, Winter, Yang, arXiv:1306.1586. The bounds imply that the two versions can be used interchangeably near α = 1, and hence one can benefit from the best properties ...
متن کاملQuantum Coding Theorems for Arbitrary Sources, Channels and Entanglement Resources
The information spectrum approach gives general formulae for optimal rates of various information theoretic protocols, under minimal assumptions on the nature of the sources, channels and entanglement resources involved. This paper culminates in the derivation of the dense coding capacity for a noiseless quantum channel, assisted by arbitrary shared entanglement, using this approach. We also re...
متن کاملCoding Theorems via Jar Decoding
In the development of digital communication and information theory, every channel decoding rule has resulted in a revolution at the time when it was invented. In the area of information theory, early channel coding theorems were established mainly by maximum likelihood decoding, while the arrival of typical sequence decoding signaled the era of multi-user information theory, in which achievabil...
