... a temperature 150 times colder than deep space.
Sorry Conj, this is NOT a reference to Ms. Boyle's vagina
There was a very interesting article in the May issue of Wired regarding Quantum Computing.
Skim over the article and look at the drawings, am sure that those here fasciated by watch movements will appreciate the engineering here. This isn't science fiction, most of us have cell phones that are faster than our first PC's.
If you have never heard of the term here is a brief explanation that will help you understand the article better.
All current computers use silicon transistors. These traditional or classic computer store, process and send all information in the form of bits, which can have a values of 1 or 0. Basically a toggle switch on or off. In 1965 Gordon E. Moore (who in 1969 became a co-founder of Intel Corporation) wrote in a whitepaper his observation that, over the history of computing hardware, the number of transistors in a dense integrated circuit doubles approximately every 18 months There has been minor variations to Moore's law but fro something written in 1965 it is still astounding. If this rate continues at some point between 2020 or 2030 will find the circuits on a microprocessor measured on an atomic scale.
A quantum computer is controlled by the laws of quantum physics where at the nano- and atomic level, other rules prevail. Instead of bits we have a qubit (quantum bit) that can have any value between 1 and 0. A spin-based qubit leverages the fact that electrons and atomic nuclei rotate around their own axes ( hence the spin). These blow binary logic out of the water as they can rotate both clockwise and counterclockwise (equivalent to 1 and 0),in both directions simultaneously (a mix of 1 and 0). Totally unfucking possible in the traditional/"classic" world.
A few years ago a company called D-Wave announced that they are close to blowing away Moore's law and the timeframe projection (2020-2030) and already have delivered system to Google and Lockheed
The wired article above questions the whether the D-Wave box is a true quantum computer (true qubits) or a very quick "classic" one (bits) and the tests (specific algorithms, signature processing curves,etc) that will demonstrate this.
A. Deep Freezer A massive refrigeration system uses liquid helium to cool the D-Wave chip to 20 millikelvin—or 150 times colder than interstellar space.
B. Heat Exhaust Gold-plated copper disks draw heat up and away from the chip to keep vibration and other energy from disturbing the quantum state of the processor.
C. Niobium Loops A grid of hundreds of tiny niobium loops serve as the quantum bits, or qubits, the heart of the processor. When cooled, they exhibit quantum-mechanical behavior.
D. Noise Shields The 190-plus wires that connect the components of the chip are wrapped in metal to shield against magnetic fields. Just one channel transmits information to the outside world—an optical fiber cable.
