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 ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

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 IBM ...

This is going to be a column that’s divided into three sections. It’s based on a question that a student posed in the EEWeb forums, and he also sent it directly to yours truly. The core of this ...

New artificial proteins have been created to function as molecular logic gates. Like their electronic counterparts in computers, these biochemical tools can be used to program the behavior of complex ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...
