Abstract

An unlikely pair The experimental demonstration of an elusive fundamental effect is reported this week: quantum interference between two particles that are indistinguishable and that come from independent sources. Such interference can be observed only by recording a joint probability of finding the particles in two detectors in separate places. Experiments with photons have not so far succeeded in producing two-particle interference, but this time the experiment was with electrons that were manipulated in a cleverly designed interferometer fabricated in a semiconductor two-dimensional electron gas.
