Delayed-Choice Experiments and the Metaphysics of Entanglement [PDF]
, 2012 Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delayed-choice entanglement swapping is incompatible with ...

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.

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 ...

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 ...

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.

ENTANGLED MARKOV CHAINS ARE INDEED ENTANGLED [PDF]
Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2006 Entangled Markov chains (EMC) were so baptized on the basis of the conjecture that they provide examples of states, on infinite tensor products of matrix algebras, which are in some sense "entangled".2 In this paper we introduce the notion of multiple (or "many-body") entanglement and extend the two-body criterion of entanglement obtained in Ref.

Imaging high-dimensional spatial entanglement with a camera [PDF]
, 2012 The light produced by parametric down-conversion shows strong spatial entanglement that leads to violations of EPR criteria for separability. Historically, such studies have been performed by scanning a single-element, single-photon detector across a ...
