May I ask, how many connections per qubit have been achieved at this moment? In our brain, on average each neuron has 1500 connections. Some neurons may have 10000 connections. The dendrites are relatively thin; therefore many long distance connections can be established. Not sure if similar things can be achieved in D-Wave. If there exists a ceiling on the connectivity, then it will be a big problem on the learning capability. ]]>

Have you tried all-to-all coupling for all 1000+ qubits? Splitting into several hidden layers (deep learning) is based on classical thought. Perhaps for quantum computing we need to think differently – it starts with all-to-all coupling and then settles as a reservoir with a particular structure depending on the problem.
