Double-slit diffraction is a corner stone of quantum mechanics. It illustrates key features of quantum mechanics: interference and the particle-wave duality of matter. In 1965, Richard Feynman presented a thought experiment to show these features. Here we demonstrate the full realization of his famous thought experiment. By placing a movable mask in front of a double-slit to control the transmission through the individual slits, probability distributions for single- and double-slit arrangements… 
Quantum double-double-slit experiment with momentum entangled photons
TLDR
It is shown experimentally and theoretically that two-photon quantum interference disappears when the which-slit path of a photon in the double- Double-Slit is detected.
The Young-Feynman controlled double-slit electron interference experiment
TLDR
The original Feynman proposal in a modern electron microscope equipped with a high brightness gun and two biprisms, with one of the biprism used as a mask is realized, in which interference phenomena due to partial overlap of the slits are observed in the image plane.
Electron interference experiment with optically zero propagation distance for V-shaped double slit
In an electron double-slit experiment, an optically zero propagation distance condition (infocus imaging condition), in which the double-slit position was imaged just on the detector plane (image

The two-slit interference experiment is usually adopted to discuss the superposition principle applied to radiation and to show the peculiar wave behaviour of material particles. Diffraction and
Momentum exchange in the electron double-slit experiment
We provide support for the claim that momentum is conserved for individual events in the electron double slit experiment. The natural consequence is that a physical mechanism is responsible for this
A possible solution to the which-way problem by asymmetrical double-slit experiments
The recent state-of-the-art double-slit experiments with single electrons and single photons seem to emphasize a contradictable dilemma concerning the ontological physical reality in quantum physics.
Testing Quantum Coherence in Stochastic Electrodynamics with Squeezed Schrödinger Cat States
The interference pattern in electron double-slit diffraction is a hallmark of quantum mechanics. A long-standing question for stochastic electrodynamics (SED) is whether or not it is capable of
Three-dimensional Quantum Slit Diffraction and Diffraction in Time
We derive a self-consistent formula for the quantum propagator of the quantum diffraction by a reflecting (or non-absorbing) screen with an arbitrary aperture, in the transmission region. To achieve
Quantum slit diffraction in space and in time of a Gaussian wave packet and semi-classical approximation
We revisit the famous problem of quantum slit diffraction of a three-dimensional Gaussian wave packet, taking into account the diffraction in time phenomenon for a reflective or absorbing slit. We
Position–momentum correlations in matter waves double-slit experiment
We present a treatment of the double-slit interference of matter-waves represented by Gaussian wavepackets. The interference pattern is modelled with Green's function propagator which emphasizes the
