Nanostructured Systems and Quantum Information

 

Quantum Information is a new area of research that combines Information Science, Physics, Mathematics, Computer Science and Engineering. One particular aspect which usually attracts considerable interest for this area is the fact that the communication or information processing using quantum systems can be applied to perform tasks that would be impractical in the Classical Theory of Information (current paradigm). These tasks include, for example, unbreakable codes (quantum cryptography) and algorithms exponentially more efficient than those currently performed on classical computers.

The practical realization of quantum computers and quantum networks for data transmission is limited by the process called decoherence. This phenomenon arises due to the inevitable coupling of the quantum system with the environment and / or due to intrinsic fluctuations (noise) present in real experiments and devices. The phenomenon of decoherence and its control are challenging topics under intense investigation in this research area. In addition, Quantum Information Science has deep meaning to the very foundation of physics. In fact, the informational point of view of Nature is a powerful tool to establish basic physical principles and technological limits currently attainable.

The manipulation of individual atoms and photons allowed the demonstration of the basic fundamentals of Quantum Information Science, but these systems are not the only ones considered today. The scenario is even more interesting considering that for multipartite systems in meso or nano scale, the occurrence of quantum manifestations may be accompanied by (or be in competition with) a wide range of interesting physical effects, typical of the mesoscopic domain. To determine what is the interplay between complex phenomena emerging from the meso-scale, and quantum phenomena, is not only fascinating but also crucial for the full understanding of how nature determines the complicated processes that occur beyond the paradigm "small, protected and elementary", typical of isolated atoms and single photons.

Quantum Information Science and Quantum Technology (meso and nano systems) are strongly interdisciplinary research areas that will play a crucial role in the technological evolution of the XXI century.

Students who opt for this line of research, "Nanostructured Systems and Quantum Information", will develop their projects in the Quantum Information Group, under the guidance of leading scientists in the field. The Quantum Information Group of UFABC is highly motivated and enthusiastic and has great international visibility. The research conducted by this group includes a wide range of topics, including:

  • Quantum Information Science (Theoretical and Experimental)
  • Nanostructures for Quantum Computing
  • Effects of Quantum Thermodynamics and mesoscopic systems
  • Quantum Metrology
  • Open Quantum Systems
