In quantum mechanics, a quantum eraser experiment is an interferometer experiment that demonstrates several fundamental aspects of quantum mechanics, including quantum entanglement and complementarity. [1] [2]: 328 The quantum eraser experiment is a variation of Thomas Young's classic double-slit experiment. It establishes that when action is ...
Many refinements and extensions of Kim et al. delayed-choice quantum eraser have been performed or proposed. Only a small sampling of reports and proposals are given here: Scarcelli et al. (2007) reported on a delayed-choice quantum-eraser experiment based on a two-photon imaging scheme. After detecting a photon passed through a double-slit, a ...
A recent experiment by Manning et al. confirms the standard predictions of standard quantum mechanics with an atom of Helium. [24] A macroscopic quantum delayed-choice experiment has been proposed: coherent coupling of two carbon nanotubes could be controlled by amplified single phonon events. [25]

The double-slit experiment (and its variations) has become a classic for its clarity in expressing the central puzzles of quantum mechanics. Richard Feynman called it "a phenomenon which is impossible […] to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery [of quantum ...
Bohr considered one of the foundational truths of quantum mechanics to be the fact that setting up an experiment to measure one quantity of a pair, for instance the position of an electron, excludes the possibility of measuring the other, yet understanding both experiments is necessary to characterize the object under study. In Bohr's view, the ...
Early quantum physicists noticed through the double-slit experiment that the act of attempting to measure photons as they pass through wavelength-sized slits to a detection screen on the other ...
The experiment has laid the foundations for the extension of the validity of the Landauer principle to the quantum realm. Owing to the fast dynamics and low "inertia" of the single spins used in the experiment, the researchers also showed how an erasure operation can be carried out at the lowest possible thermodynamic cost—that imposed by the ...
