We present our recent theoretical findings on the physics of semiconductor quantum rings containing several interacting electrons. Using time‐dependent density‐functional theory we show that the interactions preserve the Aharonov‐Bohm oscillations in quantum transport as a function of the magnetic flux, whereas increasing the ring width strongly suppresses the oscillations. Secondly, we demonstrate that various quantum Hall states in quantum rings can be characterized in a consistent way.
