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.

Multipartite entanglement of billions of motional atoms heralded by single photon
npj Quantum Information, 2021 Quantum theory does not prevent entanglement from being created and observed in macroscopic physical systems, in reality however, the accessible scale of entanglement is still very limited due to decoherence effects.

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.

Entanglement fidelity and measure of entanglement
Quantum Information Processing, 2020 The notion of entanglement fidelity is to measure entanglement preservation through quantum channels. Nevertheless, the amount of entanglement present in a state of a quantum system at any time is measured by quantities known as measures of entanglement.

Global EpidemiologyThe use of unverified models for risk estimates and policy recommendations can be highly misleading, as their predictions may not reflect real-world health impacts.

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.

Global EpidemiologyExposure-response associations between fine particulate matter (PM2.5) and mortality have been extensively studied but potential confounding by daily minimum and maximum temperatures in the weeks preceding death has not been carefully investigated.

Entanglement polygon inequality in qubit systems
New Journal of Physics, 2018 We prove a set of tight entanglement inequalities for arbitrary N -qubit pure states. By focusing on all bi-partite marginal entanglements between each single qubit and its remaining partners, we show that the inequalities provide an upper bound for each
