Devon O’Brien, technical program manager for Chrome security, explained on Thursday that starting in Chrome 116 – due August 15 – Google’s browser will include support for X25519Kyber768, an alphanumeric salad that desperately needs a catchy name.
The unwieldy term is a concatenation of X25519, an elliptic curve algorithm that’s currently used in the key agreement process for establishing a secure TLS connection, and Kyber-768, a quantum-resistant KEM that last year won NIST’s blessing for post-quantum cryptography.
Your answer is much shorter and to the point, but for the people that understand things better with visuals, here’s a Veritasium video about this exact thing

Thank you for linking it! It’s a lot easier to understand when you have images to go with it, and he goes into details about the actual cryptography that I glossed over.
