I’m working with very large matrices for QUBO problems, and I’m currently using QBsolv from D-Wave. However, given that Qbsolv is being discontinued, I identified that D-wave has 2 solutions for this type of problem: Leap’s and Hybrid solver. Would it be possible for me to use these D-Wave solutions within Amazon Braket? If the Amazon Braket does not accept using it without a specific D-wave account, what could I use from Braket itself to solve QUBO problems with extremely large matrices in a more efficient way?
