'Cryptography's Future Will Be Quantum-Safe. Here's How'

Fearing the possibility of encryption-cracking quantum computers, Quanta magazine reports that researchers are "scrambling to produce new,'post-quantum' encryption scheme."Earlier this year, the National Institute of Standards and Technology revealed four finalists in its search for a post-quantum cryptography standard. Three of them use "lattice cryptography" — a scheme inspired by lattices, regular arrangements of dots in space.
