Quantum crypto

There are two kinds of quantum crypto claimed to exist.

Quantum entanglement

Physical methods of electromagnetic quantum entanglement are claimed to make transmitted messages tamperproof “on the wire” of fiber-optic (or possibly copper wire or coaxial cable or microwave radio) and unrecoverable in the case of interception as that would cause a collapse of the wave function.

Post-quantum cryptography

Post-quantum cryptography involves classical ciphers or codes which are claimed to be resistant to attack even by quantum computers. Meanwhile the elliptic curve discrete logarithm problem on which elliptic curve cryptography is based is claimed to be vulnerable to Shor’s algorithm on quantum computers, but this has not yet been effectively demonstrated beyond trivial cases of a very few “qubits” which have not been proven to be “entangled” in any non-classical capacity beyond a “simulated annealing” which may be likened to shaking puzzle pieces around until they fall into place.

Caveat emptor

Too much of anything quantum as such hearkens to “blood quantum,” white supremacy, wars that were fought with various American Indian tribes in the 1800s, and more recently fraudulent DNA labs running paternity, child support and rape kit scams.
