5.10 CONCLUSIONS
The rising tide in miniaturization processes of electrical systems as well as
information processes is causing apparition of problems related to limita-
tions at the time of working at an atomic scale in which the quantum ef-
fects have a significant relevance. Applying models of quantum mechani-
cal in the creation of a new information model, results that exceeded the
predicted by information classical theory are obtained, incorporating them
and these last being a particular case presented by the quantum model.
Quantum computation is a new and emerging development fi eld that
has the potential of changing dramatically the way of thinking about com-
puters, programmers, and complexity. The challenges range from develop-
ing new suitable programming techniques for these devices, to the experi-
mental implementation in a scalable system.
The theoretical models of quantum computation have managed to de-
velop successfully, and at the present time, the fundaments of subatomic
interactions are broadly defi ned, as well as qubit schemes, quantum gates,
quantum parallelism, quantum transport and encryption; nevertheless at
the moment, the implementation of a fully functional quantum computer
with a relevant information storage capacity has not been achieved. A limi-
tation in this information process scheme is presented in the implementa-
tion of the device itself, in which it is diffi cult management of multiple
qubits systems where interactions affect mutually their states. Another
requirement is interactions between measurement system and measured
particle, because these cannot be read without producing changes on sys-
tem; for this cause, it is necessary to implement complex mechanics of
error correction.
At the present time, small prototypes of these computers have been
implemented; with this has been allowed to demonstrate the functional-
ity of some quantum algorithms predicting a near future full of new and
promising devices with high performance in potentiality and fast in pro-
cessing information mechanisms.
