In binary a bit is either a 1 or a 0. Basically a 1 dimensional entity. When you start talking about bytes it becomes a 2 dimensional entity. In thinking about a qubit I think 3 dimensional it comes closer. With four dimensions describing a register? The point within this fear cannot be known its location or its speed at the same time when the wave function is collapsed this three-dimensional entity becomes a 2 dimensional entity at which time you can take a look and see where it was at the time of the collapse. I'm just curious if anyone might have a better handle on what this is. I sure don't.

Inside of a qubit you can know the location of the point inside the sphere or its speed but never both.

So my visualization / analogy wasn't too far off?

 

Qubits are 2D, but the two dimensions are complex numbers as vectors with amplitude and phase. Only one of them is visible, the other is the the part that must be manipulated without measurement. When decoherence occurs, the hidden dimension is visible but consumed.

 

You could check out the Bloch Sphere, see if that provides you with more intuition.
