Scientists are one step closer to building a quantum computer based on a silicon chip Bashny.Net

The results of studies, опубликованные in the journal Nature Communications British-Dutch-Swiss team from the University of Surrey, University Gerriota-Watt in Edinburgh, University of Nijmegen St. Radboud behalf of Utrecht in Nijmegen and the Paul Scherrer Institute in Switzerland, have become an important step in the development of quantum technologies that promise mankind secure communication technology and the huge computing power, according to phys.org . Ongoing studies have demonstrated the ability to control the quantum states in a conventional silicon wafer using a laser and monitor them through conventional current measurement.

Researchers conducted an experiment demonstrated quantum switch to conventional silicon wafer, operating at 1 <sub><sup>x sup> sub> 10 -12 sup> seconds, which is thousands of times faster than the that previously achieved in experiments with silicon.

"The experiment uses the fact that according to quantum mechanics atom of matter can simultaneously be both excited and at rest. This paradox is better known as the superposition principle is illustrated by the experiment and Erwin Schrödinger cat over. "- Said Dr. Ellis Boyer, one of the researchers from the University of Surrey, who conducted the laser measurement. He added: "Such a superposition of the orbital states is very fragile, but we found that kremievaya environment creates excellent conditions for phosphorus atoms used as data cells for quantum information. Translation of atoms in the state of superposition was performed using laser FELIX installation of ultra-short laser pulses, lasting trillionth of a second. We found that creates a state of superposition is maintained even in the presence of moving electrons around an atom trapped us, but what is more strange is the fact that the very emergence of the current depends on the availability of state superposition. »

The team received funding for the continuation of his research from the Research Council of Engineering and Physical Sciences of Great Britain (UK EPSRC) in order to continue his studies at the junction of these quantum objects with each other and create computational blocks needed to create квантового computer . The next stage of research aimed at creating fast quantum chip based on silicon, as well as other devices, for example, super-accurate quantum clock and ultra-sensitive bio-medical sensors.

"Quantum superposition and deriving therefrom quantum technologies are just beginning to have an impact in science and technology. We believe that the opening of new areas of technology and the use of silicon and their use in everyday life is only a matter of time. Our work brings that day, and shows us that the earlier exotic quantum phenomena that usually demonstrated in special university physics laboratories, can be observed using a standard voltmeter. "- Said Dr. Thornton of the University of Greenland USL. "The most amazing thing is that we can observe the exotic quantum phenomena in the distribution of materials on earth - silicon, simply by measuring its electrical resistance. The time is approaching when we can build a computer, which produces a huge amount of computing time. This invention will open up tremendous opportunities for us in different areas, such as in information security. »
