DWave Systems 512 qubit quantum annealing system was mentioned in an article that mainly talks about a new proof of quantumness for a specially built and as yet non-existent two qubit system. So the researchers are saying if you build a quantum system in the way that they describe then it would be easy to prove that it is or is not quantum. But their method is useless for the systems. So they mention the Dwave System controversy but present a proof which will do nothing to settle that argument.
Dwave has many research papers that provide proof of quantum entanglement and other quantum aspects to their calculations. However, many quantum researchers dispute speedup over classical and how much and how useful the quantumness that does exist contributes.
There is new work that would provide an improved error corrected system for Dwave like quantum annealers
Arxiv - Error corrected quantum annealing with hundreds of qubits
