Want to know more about QBITS

I think 10 more IQ points would help me understand quantum physics at the level I'd like. That said, I'd like to know more about Qbits. I've watched several videos about them, and they say that they can be 1 and 0 at the same time. Is that just an analogy to the polarization of the old magnetic core, and on/off state of modern solid state bits, or is the actual physical state of a Qbit actually 1 and 0 at the same time due to superpositioning and then finally becomes binary when detected?

Qbit state is a quantum superposition of two definite states.

Googling something like 'how can a qbit hold multiple values' yields a wealth of simple explanations. Take your pick and ask specific questions.
