Abstract
The power consumption of MOS technology device
can be reduced by scaling the devices. The technology also
tries to improve speed by working on the already existing
technology. The need for new technology is fast approaching
as Moore’s law cannot hold good for next few years. For the
same purpose we should turn to quantum logic and quantum
cells. Quantum cellular automaton is one such technology.
Though the technology is in its primitive stage, many people
are working in this field. After a breakthrough in the physical
implementation of the basic quantum cell the new technology
is mainly focused on implementing digital designs. This article
is trying to review and implement the basic gates in quantum
cellular automata. Implementation is done in QCA Designer
provided by University of British Columbia.
