also, elliptic curves are much more vulnerable to quantum attacks than regular rsa since it uses smaller keys.

I wouldn't say more vulnerable necessarily — it requires fewer qubits, but requires larger coherence time. RSA requires more qubits and drastically less time. They're both vulnerable in different ways.

Isn't coherence time the big challenge?

I imagine it's a similar tradeoff - with more qubits there are more interactions, ergo lower coherence time
