Others are more elusive, like XOR and NAND. For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together with patch cables.

Traditional inverters – NOT gates – are already made with diodes (typically not light-emitting), resistors (typically not light-dependent), and bipolar transistors.

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers.

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to ...

Researchers have created the fastest logic gates ever, and they could open the door to make computers 1 million times faster.

Fastest logic gates ever made could make computers 1,000,000x faster Researchers have demonstrated the previously theoretical lightwave electronics in new logic gates operating at femtosecond speeds.

Logic gates work by taking two inputs—either 1 or 0—processing them, and providing a single output. The exact processing rules depend on the kind of logic gate implementing them, but for example, an ...

A new class of logic gates offers robust characteristics, low power consumption, and the ability to run on a very wide range of supply voltages.

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers ...
