Yes, and every physics undergraduate knows what they are
(to the extent that is relevant for understanding QC).

The actual situation is that the principles of quantum
physics are at variance with common sense and everyday
experience, which accounts for whatever air of
"mysticism" they might have. For example, it is
literally (provably) impossible for standard
probability theory (which is based on simple notions
of set measure and incomplete information) to apply to
the expectation values for quantum events. Feynman
has described this very nicely in terms of particle
paths in the two-slit experiment.

No, not effectively. I explain why in a nearby posting.
