Fraunhofer ILT in Aachen has developed a highly complex laser-optical system for a quantum computer currently under construction at the 5th Institute of Physics at the University of Stuttgart. This ...

Scientists learn to process information with 'frozen light' Scientists at Harvard University have shown how ultra-cold atoms can be used to freeze and control light to form the "core" – or central ...

A computer in which all internal circuits use light instead of electricity. Long predicted, an all-optical computer is not expected for some time as there are hurdles to overcome. However, there are ...

Researchers have successfully created an optical transistor from a single molecule. This has brought them one step closer to an optical computer. ETH Zurich researchers have successfully created an ...

Object recognition through random scattering media has been an important but challenging task in many fields, such as biomedical imaging, oceanography, security, robotics, and autonomous driving.

After a pleasant half-century of rapid improvements in electron-based computers, it's well known that the push for quicker and quicker processors (or co-processors) is hitting a wall. There are ...

A research team has developed an optical computing system for AI and machine learning that not only mitigates the noise inherent to optical computing but actually uses some of it as input to help ...

Engineers at MIT have developed a modular computer chip with components that can communicate using flashes of light. This could allow for electronics that can easily be upgraded with new sensors or ...

Modern information technology (IT) relies on division of labour. Photons carry data around the world and electrons process them. But, before optical fibres, electrons did both—and some people hope to ...

In principle, communicating with light is much, much easier than communicating with electricity. We've been doing it for much longer, in technologies ranging from signal fires to fiber-optic networks, ...

Excuse me a moment—I am going to be bombastic, over excited, and possibly annoying. The race is run, and we have a winner in the future of quantum computing. IBM, Google, and everyone else can turn in ...

A machine made from a 5-kilometre-long fibre optic cable coiled into a box a few metres across could give quantum computers a run for their money on certain tasks. The device, which performs ...
