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 ...

In the world of electronic computers, logic gates are implemented in the form of transistors, the invention of which has led to several Nobel Prizes in physics in 1956.

In conventional electronics, a NOT gate inverts the value of a bit of information from 1 to 0 or from 0 to 1. Such binary information could also be stored in two-state quantum systems, such as the ...

By entangling vibrations within a single atom, scientists have realized a long-theorized quantum code that could make ...

However, there are logic gate systems that use a property of moving fluids to form logic gates and a bistable element. That’s all the pieces you need to build a working computer.

Gate design and calibration were supported by quantum-control software from Q-CTRL, a University of Sydney spin-out. This ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...

Teaching students about logic gates is often done in two parts, once on the whiteboard for the theory, and again on the breadboard for the practice. [shurik179] wasn’t a fan of the abstractio… ...
