How might spherical harmonics be relevant for quantum computing? I’m on the hunt for visualizations. (Not to be confused with the Bloch Sphere!)
There's nothing particularly special about them, and they fail to be a good basis set for solutions of other types of quantum systems. Conversely, they can be useful for non-quantum systems - any sort of wave equation in a sphere.
It's not an intrinsically quantum mechanical thing.
