Quantum logic gates between different isotopic species are possible, can be driven by a relatively simple laser system, and can work with precision beyond the so-called 'fault-tolerant threshold' ...

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 ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

Logic gates are the fundamental components of computer processors. Conventional logic gates are electronic – they work by shuffling around electrons – but scientists have been developing light-based ...

Researchers have achieved a quantum logic gate with record-breaking 99.9% precision, reaching the benchmark required theoretically to build a quantum computer. Researchers at the University of Oxford ...

Phase change materials can switch between two forms depending on how quickly they’re cooled. Cool them quickly and you get an amorphous form, which provides significant resistance to the flow of ...
