Unified View of Quantum and Classical Correlations
Kavan Modi, Tomasz Paterek, Wonmin Son +2
We discuss the problem of the separation of total correlations in a given quantum state into entanglement, dissonance, and classical correlations using the concept of relative entr…
Extreme nonlocality with one photon
Libby Heaney, Adan Cabello, Marcelo F. Santos +1
Quantum nonlocality is typically assigned to systems of two or more well separated particles, but nonlocality can also exist in systems consisting of just a single particle, when o…
Quantum physics meets biology
Markus Arndt, Thomas Juffmann, Vlatko Vedral
Quantum physics and biology have long been regarded as unrelated disciplines, describing nature at the inanimate microlevel on the one hand and living species on the other hand. Ov…
Nested Quantum Error Correction Codes
Zhuo Wang, Kai Sun, Hen Fan +1
The theory of quantum error correction was established more than a decade ago as the primary tool for fighting decoherence in quantum information processing. Although great progres…
The work value of information
Oscar C. O. Dahlsten, Renato Renner, Elisabeth Rieper +1
We present quantitative relations between work and information that are valid both for finite sized and internally correlated systems as well in the thermodynamical limit. We sugge…
Entanglement at the quantum phase transition in a harmonic lattice
Elisabeth Rieper, Janet Anders, Vlatko Vedral
The entanglement properties of the phase transition in a two dimensional harmonic lattice, similar to the one observed in recent ion trap experiments, are discussed both, for finit…
