Real Cryptographers are Mathematicians, Beware of Everyone Else

With the advent of the digital computer, the mathematical cryptographer was born. Now physicists dare to propose cryptographic primitives rooted in the very essence of matter, rather than through mathematical trickery. Is Quantum Computing 21st century snake oil?
