The Tech FAQ

Many People use the term “Quantic Computing” to describe a much larger computing power than the one exists today. But what is “Quantic Computing”?

Searching huge databases, creating unbreakable encryptions and many more, these are applications that take a long time to complete by today’s computers. Quantic computers will perform these actions in seconds. Quantic Computers are theoretical devices that are based upon quantum mechanics, which is a Physics theory dedicated to Energy and Matter in an atomic level.

The Quantic computer term was established by the physicist Richard Feynman in 1981. When you try to calculate the predication of the Quantum Mechanics operating in large physical systems it seems that a regular computer, which is built on Classic mechanics (Newton laws and all that… :)) can not do it. The reason is the complexity of the calculations involved. But Nature itself does it all the time when the Physical system exists in reality! It seems that Nature, operating according to Quantum Mechanics has the edge over classic computers in things that regard calculation power. If that is true, maybe we can build a new type of computers that use Quantic effects to calculate things more effectively. On the basis of this theory many models of Quantic computers, which operate on the Quantic Theory laws, were defined. The computation ability of these computers were tested and found much “stronger” than that of classic computers.

Quantic computers operate by storing “qubits” and operating on them, much like the classic computer which uses bits. What are qubits you ask? Let’s talk about bits first. A bit is a basic unit of information that is represented by 1 or 0, a qubit will be represented as 1 or 0 exactly the same way as bits do, but a qubit will have the ability to be 1 or 0 at the same time. Scientists call this “Super Position”. The option to be 1 or 0 at the same time will allow the Quantic computer to process several problem solutions at the same time. It is like a huge parallel processor. This system has many advantages such as: working on problems with a large amount of data that change rapidly. With Quantic computers you can solve very complex problems that take infinite time to solve on classic computers.

Early in 2007 the Canadian company D-Wave systems claimed that it managed to demonstrate processing on a Quantic computer. It was said by D-Wave that the demonstration is a big step forward in solving commercial and scientific problems that were considered unsolvable until now.

Many voices in the computer industry expressed doubt regarding Quantic computers, especially due to the fact that D-Wave published very little information about its machine and the demonstration itself was not very impressive. It was said the what D-Wave showed problems that could have been solved with classic computers at a reasonable time.

Despite that, it is believed that Quantic computing is something that is bound to happen, what do you think?
