Learning quantum physics is a bit troublesome. Basic concepts are rather abstract and some of the consequnces seem to be counterintuitive. Here you can find some information about the way foeXlab is working on this field:
Do you want to learn something about statistics in optical science? Please take this.
Do you want to learn something about quantum optics? Please take this.
Do you want to learn something about key experiments with true single photons? Please take this.
Do you want to see what we do get information about the pupils think about quantum physics? Please take this.
And please don't forget: It may be difficult, but it is absolutely not impossible.
