The Case Against Quantum Computing
by Mikhail Dyakonov Quantum computing is all the rage. It seems like hardly a day goes by without some news outlet describing the extraordinary things this technology promises. Most commentators forget, or just gloss over, the fact that people have been working on quantum computing for decades—and without any practical results to show for it.
We’ve … -
Quantum Key Distribution Whitepaper
https://www.ncsc.gov.uk/whitepaper/quantum-key-distribution (ncsc.gov.uk) This white paper describes our current position on quantum key distribution (QKD). QKD is an approach to key distribution that relies on the properties of quantum mechanics to provide security. ...
For all the practical, business and security reasons given above, at this point in time we:
do not endorse QKD for any … -

Defeating Quantum Algorithms with Hash Functions
In this post I’ll explain why quantum computers are useless to find hash function collisions, and how we can leverage this powerlessness to build post-quantum signature schemes. I’ll then describe a quantum computing model that you can try at home, and one where hash function collisions are easy to find...
