Optical logic gates promise computing at the speed of the carrier wave, and metasurfaces provide their most compact platform; yet the gate count on one aperture has grown only by adding diffractive ...

A quantum logic gate is a basic quantum device that operates on a small number of quantum bits or qubits. A unitary matrix -- a square matrix of complex numbers -- represents the quantum gate. A 2nx2n ...

Forward-looking: Semiconductors are essential for today's electronics, providing computational capabilities and the ability to control electric signals. They are also highly complex and costly, so ...

Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — namely a simple, semiconductor-free logic gate. The original paper was written ...

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 ...
