Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (Wikipedia) ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

Quantum logic gates between different isotopic species are possible, can be driven by a relatively simple laser system, and can work with precision beyond the so-called 'fault-tolerant threshold' ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...
