Department of Physics, National University of Singapore, Singapore(Dated: December 21, 2013)Coherent interactions that generate negligible entanglement can still exhibit unique quantumbehaviour. This observation has motivated a search beyond entanglement for a complete descriptionof all quantum correlations. Quantum discord is a promising candidate [5, 6]. Here, we demonstratethat under certain measurement constraints, discord between bipartite systems can be consumedto encode information that… Expand

Role of quantum discord in quantum communication a
Positivity of quantum discord is shown to be equivalent to the strong sub additivity of the Von-Nuemann entropy. This leads to a connection between the mother protocol of quantum information theoryExpand
The Elusive Source of Quantum Speedup
We discuss two qualities of quantum systems: various correlations existing between their subsystems and the distinguishability of different quantum states. This is then applied to analysing quantumExpand
Experimental quantum computing without entanglement.
The results show that even fully separable, highly mixed, states can contain intrinsically quantum mechanical correlations and that these could offer a valuable resource for quantum information technologies. Expand
Operational interpretations of quantum discord
Quantum discord quantifies nonclassical correlations beyond the standard classification of quantum states into entangled and unentangled. Although it has received considerable attention, it stillExpand
Quantum discord and the power of one qubit.
We use quantum discord to characterize the correlations present in the model called deterministic quantum computation with one quantum bit (DQC1), introduced by Knill and Laflamme [Phys. Rev. Lett.Expand
Role of entanglement and correlations in mixed-state quantum computation
In a quantum computation with pure states, the generation of large amounts of entanglement is known to be necessary for a speedup with respect to classical computations. However, examples of quantumExpand
Thermodynamical approach to quantifying quantum correlations.
The amount of work which can be extracted from a heat bath using a bipartite state shared by two parties is considered and the work deficit is derived and provides a new paradigm for understanding quantum nonlocality. Expand
Interpreting quantum discord through quantum state merging
An operational interpretation of quantum discord based on the quantum state merging protocol is presented, which has an intuitive explanationbased on the strong subadditivity of von Neumann entropy and used to provide operational interpretations of other quantities like the local purity and quantum deficit.

Signatures of nonclassicality in mixed-state quantum computation
We investigate signatures of nonclassicality in quantum states, in particular, those involved in the DQC1 model of mixed-state quantum computation [E. Knill and R. Laflamme, Phys. Rev. Lett. 81, 5672Expand
Quantum discord: a measure of the quantumness of correlations.
This work shows that absence of entanglement does not imply classicality, and considers the vanishing of discord as a criterion for the preferred effectively classical states of a system, i.e., the pointer states. Expand
