I had a look quickly at some of the research regarding Rydberg states with "n=500", I had a look at this paper HERE. These states we not produced in a Bose-Einstein Condensate and we produced in higher energetic systems. The study I refer to is interesting because it produced this kind of state in a BEC, which is at the heart of super conductor research. Usually excitations of a BEC involve adding or removing a particle, giving poles of the Green's function, these types of excitations are fairly localised in the BEC. However these Rydberg states in a BEC cause large scale excitations interacting with the majority of the condensate. Any advances in BEC-BCS theory is a good thing, another step closer to producing room temperature super conductors.

Regarding the qubits it is far more complicated than I explained, if i explained in depth the theory it would have taken days and I think I would have lost the attention of some users. It was just to give a feel of how qubit super position is the core principle. Although there are infinite possible vectors of the Bloch-Sphere, the qubit does not fully take advantage of this, but uses multiple superposition states instead of the on/off of a binary bit.

Uhhh... Now I see I might have confused people with 0 and 1.... these were state vectors of polarisation, not binary bits, an edit is needed there. Thanks.

Thanks for the comment @lemouth :)
