There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

We discuss an abstract notion of a logical operation and corresponding logics. It is shown that if all the logical operations considered are implicitely definable in a logic $\scr{L}^{\ast}$, then the ...

Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ...

Optical computing and logic circuits represent a transformative approach to information processing, utilising light rather than electrons to execute computational tasks. This paradigm leverages the ...

Magnetic skyrmions are particle-like objects that can be used as information carriers in memory and computing devices.

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 ...

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

For the first time, researchers performed logic operations -- the basis of computation -- with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods used ...

QuEra gets ready for error correction, runs operations with over 40 logical qubits. So more progress toward a functional quantum computer, but still many miles to go ...
