Entanglement of Assistance is not a bipartite measure nor a tripartite monotone

, 2006
The entanglement of assistance quantifies the entanglement that can be generated between two parties, Alice and Bob, given assistance from a third party, Charlie, when the three share a tripartite state and where the assistance consists of Charlie ...

Generalizing entanglement [PDF]

Physical Review A, 2017
The expected indefinite causal structure in quantum gravity poses a challenge to the notion of entanglement: If two parties are in an indefinite causal relation of being spacelike and timelike, can they still be entangled? If so, how does one measure the amount of entanglement?

Entanglement Properties of a Higher-Integer-Spin AKLT Model with Quantum Group Symmetry [PDF]

, 2012
We study the entanglement properties of a higher-integer-spin Affleck-Kennedy-Lieb-Tasaki model with quantum group symmetry in the periodic boundary condition.

Modular Entanglement [PDF]

Physical Review Letters, 2011
We introduce and discuss the concept of modular entanglement. This is the entanglement that is established between the end points of modular systems composed by sets of interacting moduli of arbitrarily fixed size. We show that end-to-end modular entanglement scales in the thermodynamic limit and rapidly saturates with the number of constituent moduli.

Challenging unverified assumptions in causal claims: Do gas stoves increase risk of pediatric asthma?

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

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.

Entanglement measures and approximate quantum error correction

, 2008
It is shown that, if the loss of entanglement along a quantum channel is sufficiently small, then approximate quantum error correction is possible, thereby generalizing what happens for coherent information.

Clarifying causality and information flows between time series: Particulate air pollution, temperature, and elderly mortality

Global Epidemiology
Exposure-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.

An AI assistant to help review and improve causal reasoning in epidemiological documents

Global Epidemiology
Drawing sound causal inferences from observational data is often challenging for both authors and reviewers. This paper discusses the design and application of an Artificial Intelligence Causal Research Assistant (AIA) that seeks to help authors improve ...
