TLDR
In this article, a quantum eraser experiment using a Young double slit to create interference was reported. But the experiment was performed under ''delayed erasure'' circumstances, which is not the case in this paper.Abstract:
We report a quantum eraser experiment which actually uses a Young double slit to create interference. The experiment can be considered an optical analogy of an experiment proposed by Scully, Englert, and Walther [Nature (London) 351, 111 (1991)]. One photon of an entangled pair is incident on a Young double slit of appropriate dimensions to create an interference pattern in a distant detection region. Quarter-wave plates, oriented so that their fast axes are orthogonal, are placed in front of each slit to serve as which-path markers. The quarter-wave plates mark the polarization of the interfering photon and thus destroy the interference pattern. To recover interference, we measure the polarization of the other entangled photon. In addition, we perform the experiment under ``delayed erasure'' circumstances.read more

Essential entanglement for atomic and molecular physics
TL;DR: In this article, the authors review recent experimental and theoretical progress in the study of quantum correlations under a wider perspective, with an emphasis on rigorous definitions of the entanglement of identical particles, and on entenglement studies in atoms and molecules.

TL;DR: In this paper, the output beam splitter of a Mach-Zehnder interferometer is inserted or removed after a photon has already entered the device, which illustrates the inadequacy of a naive wave or particle description of light.

Delayed-choice gedanken experiments and their realizations
TL;DR: The wave-particle duality dates back to Einstein's explanation of the photoelectric effect through quanta of light and de Broglie's hypothesis of matter waves.
An entanglement-enabled delayed-choice experiment
TL;DR: An entangled version of John Wheeler's delayed-choice gedanken experiment is performed, in which the choice of detection can be changed after a photon passes through a double-slit to avoid the measurement process affecting the state of the photon.

TL;DR: A quantum eraser experiment in which, by enforcing Einstein locality, no such communication is possible by independent active choices, which are space-like separated from the interference.

TL;DR: In the recent literature the use of the term "philosophy of quantum mechanics" is very similar to that of the corresponding term "physics of mathematics" as discussed by the authors, which includes a vast class of research: from very technical investigations about the logical foundations of the theory up to general discussions of some traditional gnoseological and metaphysical questions (such as "idealismus" versus "realismus".
