I'd have to agree with a lot of PR going around quantum computing.
@Username1 I agree that there has been some advancement along the lines of quantum computing
Having done some uni level study into quantum physics I can tell you that the field is as large as classical physics and is one reason they are looking for a unified theory.
The research needs a ton of money because there are so many fields to explore. Take comms using entanglement that is seeing some advancements. Networking using photon switches, still not sellable after 10 years after POC.
The point is that there is going to be a lot of papers produced that have one purpose and that is to secure funding. In the field of quantum whatever results are a long way off and funding is difficult, so the papers have to be juicy and promise much potential. Some almost promise the infinite probability drive is possible in our lifetime.
Some of the research is along the lines of "you cannot know the state of an electron without observing it and thus changing the state" and translating that into "the quantum state has infinite states at once and can produce the result in one go." There is a lot of money going into that one and similar research is saying that in terms of traditional computing "get the result in one cycle" (bit like the old analogue computer which had at the time what people considered infinite states, but quantum being ever so more accurate and versatile)
research needs money, to get the money they need papers that promise much potential. Then the media runs with the potential which the researchers fuel. Can the potential be achieved? Well that depends on how creative the researchers are, or how creative they were with the paper.
Gone are the days when worthy research received money with a near certainty, money now only goes to the research with the most promise, simply because there is no longer enough money/resources to go around.
