This is what I've read on the subject of q-day.
The gist is that Shor's algorithm might not be strictly necessary with a quantum annealer.

There is consensus on this question.
* ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid
ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the
default KEXAlgorithms list (after the ECDH methods but before the
prime-group DH ones). The next release of OpenSSH is likely to
make this key exchange the default method.
