NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

For general encryption, used when we access secure websites, NIST has selected the CRYSTALS-Kyber algorithm. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation.

For digital signatures, often used when we need to verify identities during a digital transaction or to sign a document remotely, NIST has selected the three algorithms CRYSTALS-Dilithium, FALCON and SPHINCS+.

I have just finished the IBM Quantum Challenge Fall 2021.

I’ll write a more detailed post later, but in general, it was only to use pre prepared functions in finance, chemistry and optimization.

Some bugs in the notebooks (error when saving, number of parameters of ansatz returning empty). Happily, instructors in Slack platform helped a lot.

These challenges are very didactic, with a little taste of practical application.

Thanks IBM for this challenge.
