Aharonov–Bohm oscillations are studied in the magnetoconductance through two micron-sized quantum rings. The structures are defined in a two-dimensional electron gas of a Ga[Al]As heterostructure by way of local oxidation with an atomic force microscope. In the experiments, the rings are used as phase-coherent detectors of the charge state of quantum dots coupled to the rings in two specific ...
