The Capacity of a Quantum Channel for Simultaneous Transmission of Classical and Quantum Information
An expression is derived characterizing the set of admissible rate pairs for simultaneous transmission of classical and quantum information over a given quantum channel, generalizing both theExpand

  • 11 June 2003
We study and solve the problem of distilling a secret key from quantum states representing correlation between two parties (Alice and Bob) and an eavesdropper (Eve) via one–way public discussion: weExpand

Correcting Quantum Errors with Entanglement
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction, allowing us to “quantize” all of classical linear coding theory. Expand

The mother of all protocols: restructuring quantum information’s family tree
We give a simple, direct proof of the ‘mother’ protocol of quantum information theory. In this new formulation, it is easy to see that the mother, or rather her generalization to the fully quantumExpand

Exact cost of redistributing multipartite quantum states.
How correlated are two quantum systems from the perspective of a third? We answer this by providing an optimal "quantum state redistribution" protocol for multipartite product sources. Specifically,Expand

Optimal Quantum Source Coding With Quantum Side Information at the Encoder and Decoder
The optimal redistribution protocol provides the first operational interpretation of quantum conditional mutual information. Expand

A Resource Framework for Quantum Shannon Theory
We advocate a unified approach to an important class of problems in quantum Shannon theory, consisting of those that are bipartite, unidirectional, and memoryless. Expand

Classical data compression with quantum side information
The problem of classical data compression when the decoder has quantum side information at his disposal is considered. This is a quantum generalization of the classical Slepian-Wolf theorem. TheExpand

Quantum Broadcast Channels
We consider quantum channels with one sender and two receivers, used in several different ways for the simultaneous transmission of independent messages, where some of the messages transmitted are quantum instead of classical, in the sense that the parties establish bipartite entanglement. Expand
