Optical computing and logic circuits represent a transformative approach to information processing, utilising light rather than electrons to execute computational tasks. This paradigm leverages the ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

MURRAY HOLLAND dreams of the day when we can switch on a very different kind of computer. Forget pressing a button and waiting for your hard drive to whirr into action. If Holland’s idea works out, ...
