"The general perception is that the electron double-slit experiment has already been performed. This is true in the sense that Jönsson demonstrated diffraction from single, double, and multiple (up to five) micro-slits [2], but he could not observe single particle diffraction, nor close individual slits. In two separate landmark experiments, individual electron detection was used to produce interference patterns; however, biprisms were used instead of double-slits [3, 4]. First, Pozzi recorded the interference patterns at varying electron beam densities. Then, Tonomura recorded the positions of individual electron detection events and used them to produce the well known build-up of an interference pattern. It is interesting to point out that the build up of a double-slit diffraction pattern has been called 'The most beautiful experiment in physics' [5, 6], while the build-up for a true double-slit has, up to now, never been reported."
Es la primera vez que se usan una "verdadera" doble rendija y al mismo las partículas iban de una en una.
#10#8 Si entráis a ver el artículo técnico al que se hace referencia veréis que sí que aporta algo nuevo. Y es que antes no se había conseguido controlar que una u otra rendija estuviera cerrada o abierta.
#1 No es lo mismo. Por lo general los Nobel de Física son serios, no como los de la paz que a veces parece un cachondeo. Sí, es la misma Academia, pero los premios científicos son más "rigurosos".
