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 ...

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.

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.

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

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.

Photonic circuits for generating modal, spectral, and polarization entanglement [PDF]

, 2010
We consider the design of photonic circuits that make use of Ti:LiNbO(3) diffused channel waveguides to generate photons with various combinations of modal, spectral, and polarization entanglement.

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.

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 ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.
