There isn’t any quantum computer currently that can function beyond a few rounds of computation before decoherence occurs, ending the ability to compute without error. All quantum computer projects are still in the research phase, and trying to overcome the decoherence issue. Until then, like fusion, it’s a purely research funded industry.

This is my understanding. Which brings me to the part I do not understand, which is, what in the world is D-Wave selling? they claim to be selling "quantum computing systems, software, and services". Are they selling purely to researchers or something? Who is buying quantum computers that cannot compute anything faster than a traditional computer?

  D-wave is somehow special case. What they have achieved and working is not what comes in your mind when you say quantum computer. They’re selling access to a special kind of quantum machine called a quantum annealer. It’s not like the general-purpose quantum computers that big companies like IBM are working on. Instead, it’s really good for specific problems, especially in optimization – like figuring out the most efficient way to do something. Who’s buying it? Well, it’s not just for researchers. Companies interested in solving complex optimization problems are potential customers. These could be businesses in logistics, finance, or even AI. The key here is that D-Wave’s tech is handy for certain tasks, but it’s not a do-it-all kind of quantum computer. Think of it as a specialized tool for specific jobs, rather than a Swiss Army knife.

    I pointed out the Quantum Annealing as a special case in a different thread. I think that it's the only one of the Quantum computing technologies that has any future. I also believe that future isn't unlimited, as I strongly suspect someone will figure out an algorithm on a conventional computer that can simulate it efficiently, thus negating its advantage.
