About D-wave CQM hybrid solver
Hello D-Wave:
As we know, CQM hybrid solver has great advantages in solving large-scale problems. However, as a curious person, I would like to know what part of work quantum and classical are responsible for when you design CQM solver, and how the CQM hybrid solver works. I have seen some of your official documents, but I still have some doubts. I hope to get your reply. Best wishes.

I will also look for this post. It's better to know what is "under the hood" from the very beginning.
As I understood from some of the papers, the heuristic module explores solution space while the quantum module translates & sends queries to the Advantage QPU. And after finding some solutions they are back to the heuristic module to produce new regions of search..
It's not very clear how exactly solution space is searched and as I understood the whole solution space is explored by some parts, while the heuristic module works in parallel using GPUs. But maybe I am wrong in understanding the architecture & the process.
P.S.
Is it available to try & use CQM hybrid solver using a Trial Plan?
What are the restrictions for the size of a problem in this case?
Hello,
Thank you for your interest in D-Wave and our Systems.
Publicly available information about our proprietary HSS (Hybrid Solver Service) solvers are available in the D-Wave Hybrid Solver Service: An Overview white paper and the HSS section of the Ocean Docs.
We are unable to provide any additional information or reveal "what is under the hood" of the proprietary HSS (Hybrid Solver Service) solvers. Including details of calculations performed on the QPU vs calculations performed classically.
Best regards,
Mohammad
