Coherent Control of Entanglement with Atomic Ensembles [PDF]
, 2011 Quantum networks are composed of quantum nodes which coherently interact by way of quantum channels. They offer powerful capabilities for quantum computation, communication, and metrology. A generic requirement for these realizations is the capability to

Device-independent characterization of entanglement based on bell nonlocality
Fundamental Research, 2021 Quantum entanglement, has been acknowledged as a precious resource due to its inherent nonclassical correlations between subsystems. These quantum correlations have the potential for many quantum processes, including canonical ones: quantum cryptography,

Partial-norm of entanglement: entanglement monotones that are not monogamous
New Journal of Physics, 2023 Quantum entanglement is known to be monogamous, i.e. it obeys strong constraints on how the entanglement can be distributed among multipartite systems. Almost all the entanglement monotones so far are shown to be monogamous.

Entanglement generation and self-correcting quantum memories [PDF]
, 2012 Building a working quantum computer that is able to perform useful calculations remains a challenge. With this thesis, we are trying to contribute a small piece to this puzzle by addressing three of the many fundamental questions one encounters along the

Physical Review Research, 2023 Topologically-ordered phases of matter at nonzero temperature are conjectured to exhibit universal patterns of long-range entanglement, which can be detected using the entanglement negativity, a mixed-state entanglement measure.

Entanglement of Superpositions [PDF]
Physical Review Letters, 2006 Given a bipartite quantum state (in arbitrary dimension) and a decomposition of it as a superposition of two others, we find bounds on the entanglement of the superposition state in terms of the entanglement of the states being superposed. In the case that the two states being superposed are biorthogonal, the answer is simple, and, for example, the ...

NONDISTILLABLE ENTANGLEMENT GUARANTEES DISTILLABLE ENTANGLEMENT [PDF]
International Journal of Modern Physics B, 2012 The monogamy of entanglement is one of the basic quantum mechanical features, which says that when two partners Alice and Bob are more entangled then either of them has to be less entangled with the third party. Here we qualitatively present the converse monogamy of entanglement: given a tripartite pure system and when Alice and Bob are entangled and ...

Quantum correlations in and beyond quantum entanglement in bipartite continuous variable systems [PDF]
, 2012 This thesis explores the role of non-classical correlations in bipartite continuous variable quantum systems, and the approach taken is three-fold. We show that given two initially entangled atomic ensembles, it is possible to probabilistically increase ...

Calculating preventable risk fractions for exposure-reducing interventions
Global EpidemiologyHow can causal models be used to quantify the fractions of risk associated with environmental and occupational exposures that would be prevented by reducing exposures by different amounts? This paper provides a constructive answer.

Anyonic entanglement and topological entanglement entropy [PDF]
Annals of Physics, 2017 We study the properties of entanglement in two-dimensional topologically ordered phases of matter. Such phases support anyons, quasiparticles with exotic exchange statistics. The emergent nonlocal state spaces of anyonic systems admit a particular form of entanglement that does not exist in conventional quantum mechanical systems.
