NOT logic

A direct quantum equivalent of an electronic NOT gate is impossible. But the best possible approximation to the universal NOT transformation has now been demonstrated using photons. Quantum mechanics ...

Chiral skyrmion flows enable new approach to nanoscale logic 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 ...

Wetware advances: Biological logic gate built by splitting viral gene

Nice picture, but I find it interesting how we're trying to shoehorn one methodology into another instead of developing the strengths of what's already there. There's a reason biology works the way it ...

Clock Gate Logic Aware Design Closure

Silicon On Chip (SOC) consists of several logical gates connected to define some functionality. Timing Closure being a well known art to ensure that every single timing path between consecutive ...
