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 ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

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 ...

Quantum computers seem to exists in a superposition of theoretical and practical states; there seems to be a lot of progress in the field, but a fully-realized quantum computer remains a hypothetical.
