Given that Preskill is one of the world's leading experts on quantum
information and is the Richard J Feynman J Feynman Professor of Theoretical
Physics at the California Institute of Technology it might be wise to
entertain the possibility that you could learn more from him about physics
than he could learn from you

Niels Bohr said it best:
"*Anyone who is not shocked by quantum theory has not understood it*."

That is the simplest possible
example of quantum entanglement involving a single Qbit, Preskill was
talking about far more complex systems where thousands or millions of Qbits
, the sort of thing you'd need for a quantum computer.
