I do not understand Variable density

Hey forum

I need to ask for a link to a page for Variable density or preferably an explanation from someone who can describe it simply. I am trying to teach myself about the function of Qubits and have run into probability density functions and cannot find a good reference on what exactly is a variable density. If anyone can provide help that would be appreciated

Thank you

If your question has to do with probability distributions, then you will need to study statistics at the college or university level (yes, calculus will be necessary).

This article discusses probability distributions: http://en.wikipedia.org/wiki/Probability_density_function

There are several other related articles.

I think SteamKing is pointing in the right direction, but it is even more complicated I'm afraid. You will also need to know about the Fokker-Planck equation, which is an equation for the time evolution of the probability density function. The solution of this equation gives you the probability that a qubit is in a certain state.

People that know more about qubits can probably tell you that it's more complicated than this...
