According to the rules of a microscopic world, where the normal laws of physics don’t work. The laws of quantum mechanics have paradoxes and relate to very strange phenomena. Quantum computing uses these strange phenomena to do things that current computers can do. A quantum bit (qubit) usually consists of a large number of particles, with inevitably large numbers of possibilities of being influenced by the environment thanks to this quantum computers properties have a special ability to solve problems that require a large number of calculations in a very small time. In addition, as they will be built with atoms, its size will be microscopic to achieving a level of unthinkable miniaturization in the microporcesadores of Silicon the possibility of transmitting qubits without sending qubits. While traditional computing to transmit these bits are copied and subsequently sent through various means of transmission, in computing Quantum is not possible.

When sending a qubit, the receiver won’t know what was your previous state with certainty, the qubit’s transmitter is transmitted disappearing from the transmitter, and reaching the receiver tele-transportado qubit, so this ends up being identical to the original. Computing with DNA is started in 1994 in a molecular biology laboratory, to resolve a fairly complex mathematical problem using a test tube with DNA. The structure of DNA molecules was used to store game information and study molecules resulting from chemical reactions for the solution. Take advantage of the Faculty of the molecules react simultaneously within a same test tube trying to a very large amount of data at the same time. On the other hand, the size of molecules situated to a comparable size which can be achieved with quantum computers.

Another important advantage is that the amount of information that can be stored is surprising, by for example, the equivalent to a trillion CDs information can be stored in one cubic centimeter. If we compare a hypothetical molecular computer with a current supercomputer we see that the size, the speed of calculation and the amount of information that can be stored are extremely improved. The speed of calculation achieved by a molecular computer can be a million times faster and the amount of information that can be stored in the same space is a trillion times higher. Although even computers of this type can not be built, since the first practical experience this area has become part of the most serious projects as an alternative to Silicon, as objectives include the creation of new models of molecular computing more powerful than existing ones and the incorporation of new algorithmic ideas. Introduces the concept of Bioinformatics of second generation. In recent years, bioinformatics has worked with many databases that stored information biological as it would appear. This has not only had positive effects: many scientists complain about the growing complexity that represents find useful information in this labyrinth of data. To improve this situation, we develop techniques that integrate dispersed information, manage distributed databases automatically selected, assessed their quality and facilitate its accessibility to researchers. Refers to integrative bioinformatics. It should not miss navigation aids for the information than ever, with more emphasis, it resides on the Internet and not in local databases. Currently scientists and universities agree that still take from 25 to 50 years to have these computers to the domestic scope.
