great discovery in the field of elliptic curves cryptography?
ECC is not resistant against quantum computers.


  Quantum complexity for breaking RSA and ECC are $O(\frac{s^9}{{(\log (s))}^5})$ and $O(s^3)$ respectively. Which $s$ is security level $(80-96)$.


So as SEJPM mentioned in comments, "ECC is less resistant against quantum computers than RSA".

One of newest post quantum cryptographic schemes is isogeny  based cryptography, and best known quantum complexity for breaking such schemes is exponential.

Also scientists believe that nowadays, providing such enormous quantum gates is very hard and may be infeasible . So 'quantum computers aren't risk for cryptography nowadays".
