A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

We’ve often said you can make a logic gate out of darn near anything. [The Action Lab] agrees and just released a video showing how he made some logic gates from chains and gears. Along the way, he ...

A soft material performs NAND logic with visible light, showing a path toward materials that process information without conventional electronic circuitry. “This project has been part of my scientific ...

A single MXene-based optical gate switches between seven Boolean logic functions via voltage, enabling trainable photonic networks for AI tasks. (Nanowerk Spotlight) All-optical logic platforms are ...

The processor in a quantum computer. The quantum chip contains the qubits as well as the quantum logic gates that manipulate the qubits. This differs dramatically from a classical computer where the ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...
