In a first, a ransomware family is confirmed to be quantum-safe

Technically speaking, there's no practical benefit to use PQC. So why is it being used?

How can something be confirmed to be quantum-safe when practical quantum computers don't exist yet?

Maths

ML-KEM is an asymmetric encryption method for exchanging keys. It involves problems based on lattices, a structure in mathematics that quantum computers have no advantage in solving over classic computing. ML-KEM is designed to replace Elliptic Curve and RSA cryptosystems, both of which are based on problems that quantum computers with sufficient strength can tackle.

Quantum algorithm exist without the need for physical hardware.

We have ideas of the sorts of things that quantum hardware accelerates and what it doesn't.
