Single photon quantum erasing: a demonstration experiment

Dimitrova, Todorka Lulcheva ; Weis, Antoine

In: European Journal of Physics, 2010, vol. 31, no. 3, p. 625

In the conventional interpretation of quantum mechanics the interference of particles in a two-beam interferometer is closely related to the problem of which-way information. One of the mysteries of quantum mechanics relies on the assumption that the wavefunction of each photon propagates simultaneously along both classically allowed paths, and that interference arises as a consequence of the...
