Nature recently published a very interesting article that could lead to a great advance in modern computing. To sum it up, it opens the gate to an optical computer, something just like and ordinary computer but instead of working with electric current, it works with light to transmit information.
An optical computer would be great because we would be able to transfer information much more quickly as light travels much faster than a signal in electric current. An application of optics to transmission of information that everybody knows about is the optic fiber, and an optical computer would be able to manipulate information as fast as it is transmitted via optic fiber cables throughout the world.
Another huge step (and in a different direction) that modern computers are taking is the world of quantum computers, which, roughly, are able to use more than zeroes and ones, using (besides these previous 2) a superposition of them.
I have been thinking about some sort of "unification" of optical and quantum computing. This, in my idea, would be a computer that transfers information trough light, and, more than that, is able to use superposition (thus, it would be an optical quantum computer, i think). Is such a thing "possible", scientifically speaking? If it is not possible trough superposition, can we use entanglement?
