Quantum Computing Breakthrough: Oxford University Scientists Achieve Amazingly Accurate Logic Gate / Maryland University Researchers Design Programmable Quantum Computer (News In Science And Technology)
Computer scientists from Oxford University have made a breakthrough, which brings quantum computing even closer to reality. Researchers have managed to build a quantum version of a Fredkin gate that is astonishingly accurate.
The research has shown that single and two-qubit logic gates are possible with incredible 99.9% precision, which is the theoretical benchmark required to make a quantum computer possible.
Logic gate is one of crucial components inside every computer, and therefore most of digital systems.
Also, researchers from University of Maryland have designed the first programmable and reprogrammable quantum computer. This new research is expected to help the scientists to run multiple complex simulations and could create rapid resolutions to complex calculations in comparison to conventional computers.

That's great and exciting news, but it means we really have to start implementing some changes to bitcoin and other cryptocurrencies. As I explained here: https://steemit.com/steemit/@bergy/quantum-computing-and-cryptography-is-bitcoin-safe
Cool article. Thanks for link!
I think it wasn't that long ago that supposedly D-Wave built a working quantum computer. I think that the problem lies in people having programmed computers on x86 architecture forever.
Also, just because it has partial quantum behaviour doesn't really make it a true quantum computer, I have a feeling that this news is the same.
By the time anything of this significance hits the press, it would have already been working for quite some time, and yet we don't see any evidence of any cryptographic redundancies of the scale of RSA, SHA etc.
But have D-Wave or Google/Nasa prototyps achieved the above?
