The article is about:
- The Signal Protocol, a set of cryptographic specifications that provides end-to-end encryption for private communications. PQXDH, an upgrade to the Signal Protocol that adds a layer of protection against the threat of a future quantum computer breaking current encryption standards.
- Quantum computing, a new type of computational system that can solve some complex problems faster than classical computers, such as the hidden subgroup problem that underlies many public key cryptosystems4.
- Post-quantum cryptography, a new category of algorithms that resist quantum attacks, and how Signal has chosen CRYSTALS-Kyber as its post-quantum key encapsulation mechanism.
- The implementation and deployment of PQXDH in Signal’s client applications and the open research areas for further quantum resistance.

Haha, my bad. Updated the link:

Signals encryption is solid. When Signal updates their encryption for quantum computers, I know it was well thought out and will be well researched over time.

it actually had some issues: An Analysis of Signal’s PQXDH
