Iranian Scientist Changes Quantum Calculations

Sunday, November 11, 2007

Atomic physics is the research field of a young Iranian researcher at Harvard University of the United States who has opened a new chapter in the study of mysterious world of atoms by paving the way for observation of very small particles, which are called “nothing”. Mohammad Hafezi has taken part in an interview to explain the various aspects of his discovery and its impact on a wide spectrum of problems facing atomic physicists.

Hafezi says no serious attention was paid to quantum mechanics until 10 years ago, but at present, advanced laboratories have made it possible for scientists to observe the world’s smallest particles.

“My theories highlight two aspects of quantum mechanics. One of them is new ideas which are based on the logic of quantum mechanics. The advantage of this complex field of physics can be explained by an example. For example, if a computer is based on this idea, its performance would be much more rapid. For instance, if you give it a very big number to break it into basic numbers, this would probably take until the end of the world. However, quantum calculations do this in a matter of few seconds.

Holder of the gold medal of International Physics Olympiad of Iceland in 1998 further noted that another issue which is being given serious attention is quantum coding which can be used for transfer of the most secret messages. This technology would be used by banks and the military. “If such transfers are done in traditional ways, information leak is possible, but quantum coding leaves no room for such concerns,” he said.

The young scientist noted that applications of this new area of atomic physics in other industries such as semiconductors have been amazing.

“In the world of semiconductors where Moore’s Law rules, the smallest artifacts belong to Intel Corporation, which measure only 45 nanometers, but the new technology will make them even smaller. As a result, in the near future, the current plans which are rooted in discoveries of the 19th century would not be useful anymore and they would change in a matter of 20 years,” he said.

“Atomic physicists have been grappling with some problems in this regard and my studies will help resolve those problems. High sensitivity of computers that are based on quantum calculations has led to a host of problems with regard to produced heat, temperature changes and small vibrancies. I and my colleagues have worked on particles which are called ‘nothing’ in ordinary jargon. They are different from other particles which we have come to know in physics. The new particles are only two-dimensional and are unique for this reason,’ he said

The Iranian researcher noted that unlike other particles, the new particles can only exist in two dimensions and would be more efficient for quantum calculations.

“My basic work was to make these particles visible and observable to other scientists in various fields of atomic physics,” he said.
