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. https://www.forbes.

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. https://www.openssh.com/releasenotes.html https://www.openssh.com/releasenotes.html
