Part one explained the physics of quantum computing. This piece explains the target — how bitcoin's encryption works, why a ...

However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

Shor's algorithm running on a large quantum computer can solve those underlying math problems in polynomial time, essentially breaking the trapdoor. That means a quantum computer could derive an RSA ...

The encryption protecting communications against criminal and nation-state snooping is under threat. As private industry and governments get closer to building useful quantum computers, the algorithms ...
