You should use Signal. Seriously. There are other encrypted messaging apps out there, but I don’t have as much faith in their longevity. In particular I have major concerns about the sustainability of for-profit apps in our new “AI” world.

@letonyo @Vinod_MIT If you follow the link nist.pqcrypto.org you will see that it is indeed part of a FOIA request. Whether that counts as a publication is up to debate, but at least it's public.

@Vinod_MIT the email exchange doesn't seem to be public. The name of the file is Re_ ieee_Redacted.pdf Interesting, the file first 3 pages are the emails, followed by a proper paper.

Wondering what papers are indexed by Google Scholar. Just received an altert that what seems to be a private email exchange between 2 colleagues from NIST cited a paper of mine.

@quantum_graeme Genuine question: Any opinion on Carlo Rovelli's "relational" re-interpretation of Everettian QM (which does away with the many worlds by sacrificing the subject/object division)?

@QuantumYakar @letonyo @DulwichQuantum (Of course most implementers will—and should!—employ hybrid systems, i.e. both post-quantum and pre-quantum algorithms, but that does not make it any less of a publicity stunt at this point, just not outright stupidity.)

@QuantumYakar @letonyo @DulwichQuantum It's a lot easier to break an immature PQC implementation than it is to build a cryptographically relevant quantum computer and solve discrete logarithms.

the point is that you don't need to wait for a QC before PQcrypto becomes relevant. If someone stores all the communications today (easy!) and gets access to a QC in 20-30 years, they will be able to decrypt everything then. This is an issue for data that need to remain secret.

@QuantumYakar @letonyo @DulwichQuantum Yes, but if Zoom uses PQC for encryption, that would mean that the case Anthony mentions is already being covered, and that Zoom may be right in prioritizing efficiency over quantum-securing authentication for the time being.

@Heum @letonyo What am I missing? Did Zoom’s announcement on using PQC refer to the authentication part only, and not to the video data itself?

If you're in the EU and you're not ready to delete your facebook account for whatever reason (I feel you—I *wish* I could get rid of mine), then this is hopefully a path to at least not have your face stored forever in the mind of their new Meta AI system: reddit.com/r/facebook/com…

Dulwich challenge: are there unitary matrices U and V such that U + V is also unitary?

Had a chat with these awesome guys the other day about Chen's LWE algorithm. (Fun fact, the news about the bug in step 9 dropped only 15 minutes before the interview!) #eprint555
Quantum News Monthly@QuantumNewsMtly

A preprint dropped couple weeks ago *almost* broke Post-Quantum Cryptography (PQC) and got everyone in the quantum & crypto communities excited! In this video, let's see what this is all about, with an awesome interview w/ PQC expert Dr. @Heum! (1/5)
