Classical Vs Quantum correlations in composite systems
Luigi Amico, Sougato Bose, Vladimir E. Korepin +1
Here we provide the contributions' abstracts published in a volume we edited as a special issue in International Journal of Modern Physics B. The volume deals with the recent progr…
Correlations in Quantum Physics
Ross Dorner, Vlatko Vedral
We provide an historical perspective of how the notion of correlations has evolved within quantum physics. We begin by reviewing Shannon's information theory and its first applicat…
Requirement of Dissonance in Assisted Optimal State Discrimination
Fu-Lin Zhang, Jing-Ling Chen, L. C. Kwek +1
A fundamental problem in quantum information is to explore what kind of quantum correlations is responsible for successful completion of a quantum information procedure. Here we st…
A measure of majorisation emerging from single-shot statistical mechanics
Dario Egloff, Oscar C. O. Dahlsten, Renato Renner +1
The use of the von Neumann entropy in formulating the laws of thermodynamics has recently been challenged. It is associated with the average work whereas the work guaranteed to be…
Toward quantum simulations of biological information flow
Ross Dorner, John Goold, Vlatko Vedral
Recent advances in the spectroscopy of biomolecules have highlighted the possibility of quantum coherence playing an active role in biological energy transport. The revelation that…
How uncertainty enables non-classical dynamics
Oscar C. O. Dahlsten, Andrew J. P. Garner, Vlatko Vedral
The uncertainty principle limits quantum states such that when one observable takes predictable values there must be some other mutually unbiased observables which take uniformly r…
An Information--Theoretic Equality Implying the Jarzynski Relation
Vlatko Vedral
We derive a general information-theoretic equality for a system undergoing two projective measurements separated by a general temporal evolution. The equality implies the non-negat…
Using Temporal Entanglement to Perform Thermodynamical Work
Vlatko Vedral
Here we investigate the impact of temporal entanglement on a system's ability to perform thermodynamical work. We show that while the quantum version of the Jarzynski equality rema…
Measurement and Particle Statistics in the Szilard Engine
Martin Plesch, Oscar Dahlsten, John Goold +1
A Szilard Engine is a hypothetical device which is able to extract work from a single thermal reservoir by measuring the position of particles within the engine. We derive the amou…
Quantum discord as resource for remote state preparation
Borivoje Dakic, Yannick Ole Lipp, Xiaosong Ma +8
Quantum entanglement is widely recognized as one of the key resources for the advantages of quantum information processing, including universal quantum computation, reduction of co…
Operational Significance of Discord Consumption: Theory and Experiment
Mile Gu, Helen M. Chrzanowski, Syed M. Assad +5
Coherent interactions that generate negligible entanglement can still exhibit unique quantum behaviour. This observation has motivated a search beyond entanglement for a complete d…
Measuring quantumness via anticommutators
Rosario Fazio, Kavan Modi, Saverio Pascazio +2
We introduce a method to witness the quantumness of a system. The method relies on the fact that the anticommutator of two classical states is always positive. We show that there i…
