Research on hidden variable theories: A review of recent progresses

M Genovese - Physics Reports, 2005 - Elsevier
Quantum Mechanics (QM) is one of the pillars of modern physics: an impressive amount of
experiments have confirmed this theory and many technological applications are based on …

Ultrabright source of polarization-entangled photons

PG Kwiat, E Waks, AG White, I Appelbaum… - Physical Review A, 1999 - APS
Using the process of spontaneous parametric down-conversion in a two-crystal geometry,
we have generated a source of polarization-entangled photon pairs that is more than ten …

Nonmaximally entangled states: production, characterization, and utilization

AG White, DFV James, PH Eberhard, PG Kwiat - Physical review letters, 1999 - APS
Using a spontaneous-down-conversion photon source, we produce true nonmaximally
entangled states, ie, without the need for postselection. The degree and phase of …

The inflation technique for causal inference with latent variables

E Wolfe, RW Spekkens, T Fritz - Journal of Causal Inference, 2019 - degruyter.com
The problem of causal inference is to determine if a given probability distribution on
observed variables is compatible with some causal structure. The difficult case is when the …

Device-independent bounds for Hardy's experiment

R Rabelo, LY Zhi, V Scarani - Physical Review Letters, 2012 - APS
In this Letter, we compute an analogue of Tsirelson's bound for Hardy's test of nonlocality,
that is, the maximum violation of locality constraints allowed by the quantum formalism …

Increased success probability in Hardy's nonlocality: theory and demonstration

DM Tran, VD Nguyen, LB Ho, HQ Nguyen - Physical Review A, 2023 - APS
Depending on the way one measures, quantum nonlocality might manifest more visibly.
Using basis transformations and interactions on a particle pair, Hardy logically argued that …

[PDF][PDF] The mystery of the quantum cakes

PG Kwiat, L Hardy - American Journal of Physics, 2000 - neuro.bstu.by
As one of the cornerstones of quantum mechanics QM, and thus of modern science, it is a bit
unfortunate that the concept of entanglement is so difficult to grasp, even for physicists, and …

Experimental test of the violation of local realism in quantum mechanics without Bell inequalities

G Di Giuseppe, F De Martini, D Boschi - Physical Review A, 1997 - APS
We report the results of an experiment in which postselected polarization-entangled photons
were used to test the recent nonlocality proof by L. Hardy [Phys. Rev. Lett. 71, 1665 (1993)] …

Parametric source of two-photon states with a tunable degree of entanglement and mixing: Experimental preparation of Werner states and maximally entangled mixed …

C Cinelli, G Di Nepi, F De Martini, M Barbieri… - Physical Review A …, 2004 - APS
A parametric source of polarization-entangled photon pairs with striking spatial
characteristics is reported. The distribution of the output electromagnetic k modes excited by …

Paradox with phase-coupled interferometers

S Etezad-Razavi, L Hardy - Physical Review A, 2024 - APS
A pair of interferometers can be coupled by allowing one path from each to overlap such that
if the particles meet in this overlap region, they annihilate. It was shown by one of us over 30 …
