Theres a lot of reasons this isn't possible, let alone probable.
1. The "algorithms" are input by the users, not dwave. Moreover, you don't even have a way to input an NP-complete problem. You can only input the setup for a very specific type of optimization problem.
2. You're not comparing like with like. Even Dwave doesn't claim to have a general, gate based quantum computer like the sub-100 gate quantum computers you're talking about. The also don't claim coherent entanglement of all 2k qubits; they've still failed to convince anybody more than a handful get entangled together coherently during the operation of the device.
3. The dwave has yet to beat a laptop at any problem, let alone the NP-complete problems of their customers. The only people who buy D-Wave systems are those doing pure research.
4. The sales contracts aren't protected by NDAs. I've talked to people who work on Lockheed's D-Wave (at USC), and all their investigations are freely available on the Arxiv.
- dmfdmf 10y agoOkay, so where is the beef? u/krastanov blasted me too but the question remains, what are they doing? How can they sell single computer if your point #3 is true? I would think that researchers must be smart enough to sniff out a scam so I have to think DW must offering some thing new, different or superior to standard CPUs or processing -- even if primitive and expensive. Moreover, if your point #2 is true then how can they claim to be offering a 2K qbit computer? It makes no sense as long as words have real meaning. Thanks for point #4, I will investigate.
- kirrent 10y agoYour confusion here is exactly why everyone is so down on D-wave. All the parents points are true which is why it's hard to take their hype seriously.
- johncolanduoni 10y agoLook at it from the perspective of the people who have bought their computers (e.g. Google, Lockheed). Suppose there's any remote chance this is the first step towards scalable quantum computing. If that's the case, getting your researchers in on the ground floor could lead to what would likely be one of the most valuable pieces of IP since the transistor. D-Wave's patents might not cover it since their patents describe devices that don't really appear to work, and you're big enough to buy them if they do. Governments, every physical science, and plenty of firms big data would be dying to get their hands on your devices. Now look at the cost of the D-Wave. A few million dollars, compared to the trillions you could make just in licensing fees if it pans out and you were the ones to crack the code. Considering how deep these companies' pockets are, wouldn't you take that bet? I would, and I side with the evaluations of some of the biggest D-Wave skeptics in academia.
