Reconstructing the quantum critical fan of strongly correlated systems using quantum correlations. [PDF]
Nat Commun, 2019 Albeit occurring at zero temperature, quantum critical phenomena have a huge impact on the finite-temperature phase diagram of strongly correlated systems, giving experimental access to their observation.

Computing conditional entropies for quantum correlations. [PDF]
Nat Commun, 2021 The rates of quantum cryptographic protocols are usually expressed in terms of a conditional entropy minimized over a certain set of quantum states. In particular, in the device-independent setting, the minimization is over all the quantum states jointly

Informationally restricted quantum correlations [PDF]
Quantum, 2020 Quantum communication leads to strong correlations, that can outperform classical ones. Complementary to previous works in this area, we investigate correlations in prepare-and-measure scenarios assuming a bound on the information content of the quantum ...

Branching Space-Times, 2021 This chapter analyzes the phenomenon of quantum mechanical correlations using the BST notions of transitions, propensities, and funny business. It considers two ways of understanding such correlations: First, as modal correlations (exhibited, e.g., in ...

Measurement-Based Quantum Correlations for Quantum Information Processing. [PDF]
Sci Rep, 2020 Measurement-based quantum correlations (MbQCs) depend on how strongly an observer perturbs the unobserved system. This distinctive property differentiates MbQCs from traditional quantum correlations such as entanglement and discord.

Discriminating quantum correlations with networking quantum teleportation [PDF]
Physical Review Research, 2020 The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

Reversing the direction of heat flow using quantum correlations. [PDF]
Nat Commun, 2019 Heat spontaneously flows from hot to cold in standard thermodynamics. However, the latter theory presupposes the absence of initial correlations between interacting systems.

Hierarchy of quantum correlations using a linear beam splitter. [PDF]
Sci Rep, 2018 Beam splitters are important components in numerous tasks of quantum information protocols used either in simple or in an interferometric arrangement or together with other quantum systems.

Quantum correlations are weaved by the spinors of the Euclidean primitives. [PDF]
R Soc Open Sci, 2018 The exceptional Lie group E8 plays a prominent role in both mathematics and theoretical physics. It is the largest symmetry group associated with the most general possible normed division algebra, namely, that of the non-associative real octonions, which—

Springer Theses, 2019 As we step into the era of quantum technologies, determining whether the correlations between physical systems are quantum or classical plays a fundamental role in our understanding of the physical world and our ability to use such correlations for novel applications.
