Thanks. I spoke to the CEO of D-Wave a little while ago and he mentioned the team trying to disprove the D-Wave work. He pointed out that they had not submitted any work to the journal to challenge the work and they openly admit that they had not managed to replicate the D-Wave work but that they thought they would be able to. There is a big difference between saying you think you can do something and actually doing it.
Thanks for linking that. It will take sometime for me to come to a complete conclusion, the paper involves some maths I am not familiar with. The abstract is promising for D-Wave as the approach could only simulate 300 qubits when D-Wave are running with 5,000. The paper also indicates that they have found a viable approach using tensor networks but did not manage to complete the work. On the face of it this does not sound that believable, tensor networks are a well known method for this type of problem but no one has been able to scale them.
I slogged through it yesterday and did enjoy reading it.
I got the gist of it, but your summary very much makes it more comprehensible.
What can I say but "Top Dog and First Mover in an Important, Emerging Industry" lol
Thanks for this very helpful post!
Another confusing article just published.

Than you, very informative and well written.
Have you also looked into what the critics have to say too?

Seems they have published a new article challenging D-wave claims.
Any thought on that?
