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 ...

Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. This technique improves upon the phase-change optical memory ...

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 ...

Modular optical computer chip allows stackable swappable functions By Michael Irving June 20, 2022 MIT engineers have developed a new modular computer chip that uses flashes of light to communicate ...

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 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 ...

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 ...

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, ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

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 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 ...

One of the attractive features of early optical computer mice was their lack of moving parts. The idea is that fewer moving parts translate into less mechanical wear and longer life. But even though ...
