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
Information causality as a physical principle

Quantum physics has remarkable distinguishing characteristics. For example, it gives only probabilistic predictions (non-determinism) and does not allow copying of unknown states (no-cloning).… Expand
Operational Resource Theory of Coherence.
We establish an operational theory of coherence (or of superposition) in quantum systems, by focusing on the optimal rate of performance of certain tasks. Namely, we introduce the two basic… Expand
Structure of States Which Satisfy Strong Subadditivity of Quantum Entropy with Equality
We give an explicit characterisation of the quantum states which saturate the strong subadditivity inequality for the von Neumann entropy. By combining a result of Petz characterising the equality… Expand
“Squashed entanglement”: An additive entanglement measure
- M. Christandl, A. Winter
- Physics, Mathematics
- 16 August 2003
In this paper, we present a new entanglement monotone for bipartite quantum states. Its definition is inspired by the so-called intrinsic information of classical cryptography and is given by the… Expand
Entanglement and the foundations of statistical mechanics
- S. Popescu, A. J. Short, A. Winter
- Physics, Mathematics
- 23 November 2005
Statistical mechanics is one of the most successful areas of physics. Yet, almost 150 years since its inception, its foundations and basic postulates are still the subject of debate. Here we suggest… Expand
Quantum mechanical evolution towards thermal equilibrium.
- N. Linden, S. Popescu, A. J. Short, A. Winter
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 12 December 2008
The circumstances under which a system reaches thermal equilibrium, and how to derive this from basic dynamical laws, has been a major question from the very beginning of thermodynamics and… Expand
Coding theorem and strong converse for quantum channels

TLDR
Quantum State Merging and Negative Information
- M. Horodecki, J. Oppenheim, A. Winter
- Mathematics, Physics
- 29 December 2005
We consider a quantum state shared between many distant locations, and define a quantum information processing primitive, state merging, that optimally merges the state into one location. As… Expand
