Is Matrix's encryption "quantum-safe"? (lemmy.world)

There's a growing concern that "bad-actors" are amassing troves of encrypted data, and storing it away for possible future decryption using quantum computers. Many services have put in efforts to make certain that their encryption algorithms are "quantum-safe", so as to protect against such attacks. Has Matrix done the same?

Until quantum computers actually exist, I wouldn’t believe a lot of the marketing you hear about “quantum encryption “. Every time I think about this subject I think about that case where their “quantum encryption” was broken, by a regular (decade old) computer, within an hour:

Right now it’s all marketing, with some nice research. Right now we need regular, actually useable encryption.
