Summary: In this paper, the statistics of detection data in a general double-double-slit experiment are analyzed. The detection times of the two particles are generally unequal, and the distances of left and right screens from their slits, as well as the ratio, have no constraints, leading to different timescales of detection. While the orthodox formalism lacks a clear prediction of random events and the quantum state afterward, the Bohmian framework implemented in this paper provides a straightforward method to study this problem and predict the system up to the end of the experiment. The main result is the joint distribution of detection data, including the arrival time and position of particles on left and right screens. It is observed that while the joint spatial distribution can be affected by changes to the relative location of screens, the marginals on each side remain intact, supporting signal locality. Furthermore, the result is shown to be highly sensitive to quantum equilibrium conditions.

Summary: In this study, a laser beam asymmetrical double-slit experiment was successfully performed, producing new interference samples with acceptable quality by controlling for saturation effects and upgrading the slit's shape. The experiment also made the which-way identification with higher experimental confidence.

Summary: The study indicates that responses from subjects to repeated measurements of the same attribute may vary significantly between different measurements, contrasting with the predictions of decision theory. Additionally, the response to sequel measurements also depends on whether the initial measurement has taken place.

Summary: This Letter investigates Young's double-slit experiment with vector vortex beams, analyzing the results for various Poincare-Hopf index beams and studying the morphological changes in the far-field interference pattern. The Fraunhofer pattern consists of lattices of polarization singularities, the number of which varies based on the Poincare-Hopf index of the diffracted beam, with the number of intensity nulls along the vertical line equal to the absolute value of eta.

Summary: The measurement and quantum arrival time problems in quantum theory have led to various predictions for the joint spatiotemporal distribution of particle detection events. This paper presents a feasible setup utilizing a modified double-slit experiment to test these predictions. Despite the successes of quantum mechanics, fundamental issues like the measurement problem and quantum arrival time problem have made the theory's predictions unclear and non-unique. The proposed unconventional double-slit configuration, achievable with present-day single-atom interferometry, allows for experimental distinction of these different predictions, contributing to a deeper understanding of the foundations of quantum mechanics.

Summary: We present a semiclassical description of the double-slit experiment using an augmented Hamiltonian and canonical variables. Our framework allows for the study of quantum systems and captures the evolution and collective behavior that reproduces the quantum interference pattern. Unlike Bohmian mechanics, our description allows particle trajectories to cross each other. We also discuss the potential extensions and applications of this quantum-effective potential.

Summary: Maximally entangled NOON states can be generated with N independent photons and a fixed double-slit in the Young's interference experiment. The photons need to be arranged in a straight line and separated by equal distances. Experimental investigation shows that the high-order correlation functions of the N-photon wave packets of the NOON states can be imitated using a spatially random laser beam. Superresolved fringes up to fourth order can be observed using the product of second-order correlation functions or the measurement of 2Nth-order correlation functions.

Summary: Introducing thiophene rings into carbohelicenes has electronic effects that can be beneficial in organic electronics. The performance of these devices depends on the sulfur atom topology, requiring precise knowledge of synthetic routes. Studying the photocyclization pathway of 2- and 3-styrylthiophenes reveals insights into their electronic spectra and reaction outcomes.

Summary: Wave-particle duality is a counterintuitive nature of quantum physics, and Young's double-slit interference is used as an example. In this study, frequency entanglement is used to create a nonlocal temporal double-slit interferometer, where the which-time information determines the behavior of the photons. By delaying one of the entangled photons, the mark of temporal distinguishability is prepared and its quantum eraser is implemented using spectrally resolved detection. These findings provide insights into the role of the temporal degree in quantum-light complementarity and photon interference.

Summary: Due to the increasing complexity of optimization problems, deterministic and heuristic approaches are insufficient. Metaheuristics, particularly the Young's Double-Slit Experiment (YDSE) optimizer proposed in this paper, have emerged as effective alternatives. The YDSE optimizer is inspired by Young's double-slit experiment in classical physics and balances exploration and exploitation using constructive and destructive interference. Through comparisons with other metaheuristics on various benchmarks, it has proven superior performance and outperformed previous winners. Published by Elsevier B.V.

Summary: The interference observed in a double-slit experiment definitively demonstrates the wave properties of particles, and a quantum mechanical double-slit interferometer is constructed using molecular deuterium. The existence of two indistinguishable quantum mechanical pathways connecting initial and final states of the colliding system is established through the biaxial state.

Summary: We establish entanglement monotones in terms of an operational approach, showing that any good entanglement quantifier defined on pure states can induce an entanglement monotone for all density matrices, with our proposed monotone being the maximum among those with the same form in pure states. In certain special cases, our proposed entanglement monotones are equivalent to the convex roof construction, giving them an operational meaning.
