Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate ...

Computers come in many forms, depending on your definition. We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they ...

In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips—and we've covered a number of reports in this ...

Quantum computing is a devilishly complex pursuit and one of the main problems is that it demands exotic materials to create its equally exotic circuitry. Now a team of researchers has managed to ...

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 ...
