Physics, Computer Science
IEEE Transactions on Information Theory
18 April 2003

We have defined and found expressions for the private information transmission and secret key generation capacities for classical-quantum wiretap channels and quantum channels . Expand

The Capacity of a Quantum Channel for Simultaneous Transmission of Classical and Quantum Information

I. Devetak, P. Shor
Physics, Mathematics
19 November 2003

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 the… Expand

Distillation of secret key and entanglement from quantum states

I. Devetak, A. Winter

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: we… Expand

Correcting Quantum Errors with Entanglement

T. Brun, I. Devetak, Min-Hsiu Hsieh

11 October 2006

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

A. Abeyesinghe, I. Devetak, P. Hayden, A. Winter
Mathematics, Physics
Proceedings of the Royal Society A: Mathematical…
27 June 2006

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 quantum… Expand

Exact cost of redistributing multipartite quantum states.

I. Devetak, Jon T. Yard
Physics, Medicine
Physical review letters
6 December 2006

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

Jon T. Yard, I. Devetak
Physics, Mathematics
IEEE Transactions on Information Theory
20 June 2007

The optimal redistribution protocol provides the first operational interpretation of quantum conditional mutual information. Expand

A Resource Framework for Quantum Shannon Theory

I. Devetak, A. Harrow, A. Winter
Mathematics, Physics
IEEE Transactions on Information Theory
2 December 2005

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

I. Devetak, A. Winter
Physics
3 September 2002

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. The… Expand

Quantum Broadcast Channels

Jon T. Yard, P. Hayden, I. Devetak
Mathematics, Physics
IEEE Transactions on Information Theory
10 March 2006

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
