And these are the same quantum computers that will eventually break ecliptic curve cryptography? Now I’m very confused.

"Is this what you can conjure Saruman?"

I have a strong belief that new mathematical tools and methods can be developed that can make it "easy" to break a lot of modern cryptography primitives without ever using a quantum computer.
