Quantum computer - 18 billion billion times faster, is it realistic?

Do you want your computer to run 18 billion billion times faster?

According to a physicist at the University of Utah, the future is likely to have a new type of computer - quantum computer. He took the first step in his plan to create that computer.

This type of computer enhances the use of quantum bits (qubits), uses binary 1 and 0 at the same time but differs from position. In quantum physics, the smallest particles of light and matter can be in many different locations at the same time (such as particles of sunlight, water particles .).

For today's computers, an electronic bit (binary number) can only be in one of two states: 1 (off) or 0 (open). If there are 3 bits, they can store one of eight matching cases of 1 and 0: 1-1-1, 0-1-1, 1-0-1, 1-1-0, 0-0-0 , 1-0-0, 0-1-0 and 0-0-1.

But quantum computers can store all eight cases. Theoretically, a 3-qubit computer can calculate eight times faster than a 3-bit PC. According to this calculation, a 64-qubit computer can calculate 2 to 64 times faster than a 64-bit PC, meaning faster than 18 billion, billion times.

Boehme is working on a quantum computer reading technology

Physicist Christoph Boehme, assistant professor of physics at the University of Utah, has read archival data in the form of a magnetic "spin" of a group of thousands of phosphorus atoms. " We have demonstrated experimentally that the nuclear rotation direction of phosphorus atoms embedded in silicon solution can be determined by a lot of microelectronic currents passing through the atoms, " he said.

" We have solved a major obstacle when successfully building a specific type of self-quantum computer: phosphorus and silicon quantum computers. With this concept, readable data is the biggest problem, and we have shown the way to read new data ".

The mechanism of the operation of a quantum computer has appeared before, by the Australian physicist Bruce Kane in the article: " A silicon-based nuclear spin quantum computer " ( Quantum computer turned silicon-based nuclei). Silicon, semiconductors used in digital computer chip technology will be "released" into phosphorus atoms. The data is encoded in the "revolutions" of the atomic nucleus. Extensive applied electric fields will be used to read and implement the data storage process as "revolutions". Boehme confirmed that it is possible to read the rotation of single phosphorus atoms in a technical way.

This physicist has been studying quantum computers for years. "If you compare the development of quantum computers with traditional classical computers, it can be likened to being in a period before we find a radius. All that is just the beginning. only ".

But its machine-brain interface is billions of times slower.

Like the Hitachi research firm once pointed out, people can control the on / off switch simply by thinking about it. Optical region techniques are used to determine changes in the total amount of blood in the cerebral cortex before people are doing certain activities such as thinking about arithmetic operations or imagine singing a song. The technique of determining changes can turn on / off the railroad model.

The optical zone uses infrared light to penetrate the upper level of the cortex and then radiates back. Thanks to this radiation ability, the amount of blood changes and the level of hemoglobin concentration in the brain is measured. It all takes only a tenth of a second.

Hitachi hopes this technique will lead in the field of medical brain machine interface, which is helpful for physically impaired patients. The company also hopes that the practical results can help this product be marketed in 2011, decades before quantum computers can be built. But everything is subject to change. We cannot know for sure.
