Note that all we have here is a quantum ocean of frequencies. There is no actual "circle" there, only frequencies propagated through this ocean of single states to finally make up the apperance of circle. That is also a configuration of state frequencies.
Also note that these states are quantum sized. A grain of salt consists of approx 1.2x10^18 single states, all of both particle and wave quality.
So you see that having quantum rotation in numerous single states making up the distinct shape of a circle is not a problem. You will never detect the quantum "leaps" between single states. They are simply too small, too many, and will therefore appear as a distinct line/curve.
