Abstract
Mesoscopic Physics The coherence of electrons in mesoscopic structures is thought to be unlikely to survive in a disordered environment. Duprez et al. show that this is not necessarily the case. They studied a metallic island as an example of a disordered environment. They made an electron interferometer and incorporated the island in one of the two paths through the interferometer. At sufficiently low temperatures and in the quantum Hall regime, they observed a clear interference pattern, indicating successful transmission of the electrons' quantum state across the island.
