That's why I'm skeptical too... still, I'm glad some seriousness is been given to this issueI think I can point out a couple of sentences.
experiments show the D-Wave machines display quantum behaviour, it’s not clear this is responsible for speeding up computation.
“My initial impression is that they looked to design a benchmark on which their machine has the best chance of succeeding,”
outside experts contacted by New Scientist say the test is not a fair comparison.

I'm underwhelmed.The article said:But after four years on the market there is still no clear evidence its machines can solve problems faster than ordinary computers.
I'm.... I don't know what to think... but considering that NASA and and Google are among its customers I think there has to be some seriousness behind their research.I'm underwhelmed.
A previous test in 2013 claimed a 3600-fold performance increase but was later discredited and D-Wave took the criticisms on board. “I think they are getting much more serious in the statements they make,” Troyer says."
When what are known as zero-index materials enter the mix, light no longer behaves as a set of moving waves zipping through space as a series of crests and troughs. Instead, in zero-index materials, light behaves as either all crests or all troughs, stretched out to infinite wavelengths and traveling at infinite speeds.
It appears so.Did you just say the speed limit of light has been repealed?
It looks like, "Beam me up, Scotty" is on the horizon!It appears so.
Noy really... that's just a quote from the article that I found interesting enough to post. And of course the article further down clarifies that that's not the case. But that it gives an illusion that the signal travels at an infinite speed.Did you just say the speed limit of light has been repealed?
Interesting article. And at the bottom mentions the em drive that I was discussing in a previous post.Warp Speed may soon be a reality, but not in my lifetime.
It's not really a GP quantum computer. It's a hardwired algorithm using quantum logic bits of a carefully chosen benchmark. Very cool stuff that they proved its working as designed.Here's a very interesting new development:

GP? mind elaborating? On the other hand, are you saying that they're not quite yet there, but it's a step in the right direction?It's not really a GP quantum computer.

General Purpose computer. It's a step in proving we can use qubits for real logic circuits but a Quantum computer is not just a set of logic blocks chained like normal logic into registers, memory and an ALU. As more qubits are added the effort to keep entire quantum units logic state stable and free from errors the errors grow exponentially to the point you get errors every few operations. You can't clone qubits to generate normal error correction codes so they need to use several (inefficient) to represent one qubit and then compare to see if an error value is generated. I've seen costs of $10-billion to build the manufacture capability after maybe the 10+ years it will take to find solutions to the current problems for the 100s of encoded qubits needed for a general quantum computer algorithm.GP? mind elaborating?

crowdfunding is another venue for both legitimate research and not so legitimate research. At least they are not draining on national resources chasing a dream.scientist are trying to crowdsource quantum algorithms development

"A fool and his money" directs my mind farther back in time. More like Aesop's Fables.
