Breakthrough on the way to the quantum computer: U.S. researchers have solved a tricky problem for the future technology. Which will enable computers that could work much faster than today's models. Of euphoria, it is still too early. Quantum computers are like the Holy Grail of computer technology. Some amazing things are attributed to them.
Complex mathematical problems they will solve much faster than previous computer, juggling with large numbers as they would encrypt kids stuff and secrets so sure that they can be brought out by any code breakers. But what is auspicious sounds is now nothing but future. For years, researchers are experimenting with the new technology, a quantum computer, they have so far still can not build.
But the goal was to come a lot closer, Erik Lucero said of the University of California at Santa Barbara now on a physics conference. The problem is that quantum computers are completely different from current computer. All currently available processors know only two states: on or off, zero or one, electricity or no electricity.
Therefore, one speaks to them of binary systems. A quantum computer, however, can take several states simultaneously. From scientists this ability is so-called quantum bits, qubits short, as a superposition call. The special feature here is that a quantum computer can be expected, together with all items of a Super qubits.
He works as it were super parallel, can perform many calculations simultaneously. This effect is multiplied when several qubits working in a computer. But it is exactly what researchers previously very difficult. The fusion of several qubits is extremely complex and the problems that confronted the physicists now are comparable with those that had to meet the developer of the first transistors, writes "Technopolis".

Covering an area of six square centimeters - much larger than current PC processors - U.S. researchers have linked four qubits. The challenge was in finding a technique to effectively separate qubits, ie to prevent interaction between the qubits.
Only then is it possible to freeze defined conditions, to save words. Speaking to the BBC said research director John Martinis of the University of California: "I now have three or four years I've been thinking about how to prevent interactions." Now you've finally achieved that goal, but "there is still much to do other things." The next goal, the researchers have already been set.
By the end they want to make a quantum processor with ten qubits ready. If that works, that would be a tremendous acceleration of the pace of innovation in comparison to the progress of the past years. On the way to real quantum computers, such a growth pace, however, can not hurt. For competitive, the BBC, the computer with the new technology be when they work with at least 100 qubits.
