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 ...

First, some background. Magnetic domains are small regions of uniform magnetization in a material. The narrow boundaries separating different magnetization orientations are called domain walls; within ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

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 ...

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 ...

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' ...

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 ...

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 ...
