	'''Experimental quantum physics''' ~~is a Book I topic in~~ the ~~Quantum Collection. The~~ double-slit experiment is one of the most important demonstrations of the wave–particle duality of quantum systems. It shows that particles such as electrons and photons exhibit interference when not observed, but behave like classical particles when measured. The double-slit experiment is one of the most important demonstrations of the wave–particle duality of quantum systems. It shows that particles such as electrons and photons exhibit interference when not observed, but behave like classical particles when measured. A beam of particles is directed toward a barrier with two narrow slits. After passing through the slits, the particles are detected on a screen. When both slits are open and no measurement is made to determine which slit the particle passes through, the detection pattern shows interference: This indicates that the particle behaves as a wave passing through both slits simultaneously.
