Quantom Dots Utilized in Producing New Computers
Iran | Posted on March 2nd, 2010"One solution to solid state quantum computers manufacture is to use synthetic atoms quantum states (quantum dots) or other nanostructures. Moreover, manipulation and control of electron spin states play an important role in the spin electronic structure," Reza Safayee, a young Iranian physicist at Shiraz University, said to the Iran Nanotechnology Initiative Council.
Manipulation of solid spins opens up advances in the manufacture of electronic devices such as spin transistors, spin filters, and spin memory devices.
In this study, he, first, introduced Hamiltonian system with Rashba effect to study the dynamism of sublayer and electron spin states convolution in a two-dimensional quantum dot. Then, he calculated time evolution operator matrix by the mentioned system. After that, he calculated spin convolution and sublayer populations as a function of time under special initial conditions.
The results of present study show that Collapse and Revival phenomenon has frequently occurred for electron spin convolution with structural sublayer aggregation.
It is also demonstrated that the characteristics of these behaviors are controllable by external magnetic field and Rashba parameter.
Researches like this could significantly help to the manufacturing of quantum information analysis devices such as quantum computers.
