A solution to one of the key problems holding back the development of quantum computers has been demonstrated by researchers at Google and the University of California, Santa Barbara. Many more problems remain to be solved, but experts in the field say it is an important step toward a fully functional quantum computer. Such a machine could perform calculations that would take a conventional computer millions of years to complete.
The Google and UCSB researchers showed they could program groups of qubits—devices that represent information using fragile quantum physics—to detect certain kinds of error, and to prevent those errors from ruining a calculation. The new advance comes from researchers led by John Martinis, a professor at the University of California, Santa Barbara, who last year joined Google to set up a quantum computing research lab (see “Google Launches Effort to Build Its Own Quantum Computer”)

It might be that Quantum Computers have been developed, and bigbruther keeps telling us how difficult they are to make. They do not have our interests in mind, rather how to control us, make us docile. The game runs very deep, and they have our future planned. Come on, they have time and infinite resources. For them, its not about survival anymore; its about having everything, and absolute control. How else would anyone explain why some days ago Elon Musk said: A.I is very dangerous and we should be aware of that. Then Stephen Hawking repeated this, even though none of them have any experience developing or working with A.I, even when the paid press said Hawking had more street cred than Elon Musk.
In similar vein:
It also seems that they are good at reading peoples minds. Their original program started in the 1960's (or earlier) when the US govt hired people to read Soviet scientists minds. It looks as if they got really good at it, and now all governments of the world know of this technique, and have perfected it.
I hope I am wrong.

Don't worry: If it's like a lot of quantum mechanics, it will simultaneously work perfectly and not work at all.
The only thing that stops a bad guy with a compiler is a good guy with a compiler.

In fact, it will work, but only when you don't observe the computation.
Debugging will be hard !

It'll be quantum encryption in the end.

True, but there's a fair amount of research into post-quantum cryptography [wikipedia.org] which shows promise. Hopefully one of those algorithms will be production ready before quantum computers are.

In the context: "error = not the kind of result Google likes"?
