A quantum computer in the next decade could crack the encryption our society relies on using Shor's Algorithm. Head to https://brilliant.org/veritasium to st...

Veritasium is the king of almost clickbait, but he really gives out some crazy details.

Starting around 2:11 They explain RSA and get into the meat.

When quantum computers do all that crazy parallel math, apparently you only get one of the answers, and it’s random :) But due to some sketchy repeating, any one of the answers is enough to make RSA vulnerable with just a little math.
