Researchers from the University of New South Wales (UNSW) have come up with a new kind of architecture that uses standard semiconductors common to modern processors to perform quantum calculations.
Details aside, it basically means the power of quantum computing can be unlocked using the same kinds of technology that forms the foundation of desktop computers and smart phones.

"Our chip blueprint incorporates a new type of error-correcting code designed specifically for spin qubits, and involves a sophisticated protocol of operations across the millions of qubits."
This technology is the first attempt to put all of the conventional silicon circuitry needed to control and read the millions of qubits needed for quantum computing onto one chip.
In simple terms, conventional silicon transistors are used to control a flat grid of qubits in much the same way logic gates manage bits inside your desktop's processors.
"By selecting electrodes above a qubit, we can control a qubit's spin, which stores the quantum binary code of a 0 or 1," explains lead author of the study, Menno Veldhorst, who conducted the research while at UNSW.
"And by selecting electrodes between the qubits, two-qubit logic interactions, or calculations, can be performed between qubits."
IBM's quantum computers have taken a step out of the lab and into the real world as Samsung, Daimler, Honda, JP Morgan Chase, Barclays and others have signed up to use the exotic machines for research. Big Blue has ridden many waves of technology -- the mainframe, the PC, cloud computing, blockchain, among others. Now IBM is betting quantum computing will be one of the next big businesses.
The partnerships with big-name global corporations, announced Thursday, show some powerful customers are willing to pay to come along for the ride. If successful, quantum computing could help solve new types of computing problems, breathing new life into an industry that today is struggling against hard physical limits to making computer chips faster, cheaper and smaller. For decades, that miniaturization trend, called Moore's Law, kept the computing industry's economic engine humming, but the hunt is on for longer-term technologies that will keep the progress coming to us all.

They can do quantum encryption now using D-Wave.

Yes, but what happens to the value of all conventionally mined coin when they start mining with quantum computers?
The entire theoretical maximum coins would be generated so quickly that conventional coin would tumble.

They also did not say so I am assuming that this design still has to be super cooled.
We assume that the complete structure is maintained at cryogenic temperatures (∼1 K or less) inside an electron spin resonance (ESR) system, which will be used to apply qubit control pulses.

While IBM and Google are fighting to demonstrate quantum supremacy (the state where quantum technology reliably out performs today's super computers), the crazy Aussies went and did this: designed an achievable quantum computer using today's known and proven tech!

And last week Micro$oft released their programming tools for Quantum computing add-ons for Visual Studio.
Goodbye cryptocurrencies.
