Here we have developed two input logic gates
with its inversion also being available for evaluating more combinational functions.
Quantum logic gates
are the most obvious application of this advance," said Steinberg.
Although still a long way off, the team suggest that these biological logic gates
could one day form the building blocks in microscopic biological computers.
Computer-chip components called logic gates
output a 1 or 0 depending on the configuration of a gate's inputs.
Using this design strategy, the researchers can create all two-input logic gates
and implement sequential logic systems.
FPGAs contain logic gates
that can be connected and disconnected by programmable switches.
Between 1998 and 2001, Weiss took some of the first steps toward building cellular logic gates
when he modeled and built a cellular inverter, an AND gate, and two other gates.
Nanosys Incorporated announced today the publication of pioneering research by Harvard Professor and Nanosys founder Charles Lieber that demonstrates the ability to reproducibly construct nanoscale logic gates
and carry out basic computations using assembled nanoscale building blocks.
Putting switches together lets you make logic gates
, and assembling logic gates
allows you to do computation," Piccione said.
These logic gates
have the potential to work on a much smaller scale than conventional transistors because they do not rely on a flow of electrons
For example, they devised a logic gate
from a nine-by-nine grid with two places that vehicles can enter and one exit.
The system will be used for the development of a variety of advanced dielectric-constant (high-K) structures in logic gate
