Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a computer - logic gates. Using DNA and harmless gut ...

Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or neither of them ...

The underlying circuits are a complex, networked system of logic gates that generate binary input and output signals controlled by electrons as signal carriers. A long-cherished dream is to ...

DNA-based logic gates that could carry out calculations inside the body have been constructed for the first time. The work brings the prospect of injectable biocomputers programmed to target disea ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
