Think about it, what will you use as carriers of information in your future processors? The bandwidth has to match up to the processing capability of processors(reason why will measure it in terms of Hertz, a unit for frequency) in the end you will use photons, nothing but photons. As your bandwidth increases, you need to use higher and higher frequency laser-beams, which translates to higher and higher energy photons, when your photon energy reaches the level of electron rest energy, electron-pairs start to be created out of Dirac sea.
Were you dropped on your head as a child?
I can understand that you just know too little about physics after all, none of what I said violates any fundamental law of physics, in fact the humanly possible laser power is not too far away from the level required to create electron pairs.
I'm a semiconductor process engineer.
That doesn't say anything about your knowledge of optical information processing, or lasers over all, or even fundamental physics.
sigh I'm probably getting trolled.
In a natural and free ecosystem waste =food, the waste heat in mining will be put to good use soon.
In the future when humans can make routine interstellar trips and everything is powered by natural or man-made nuclear fusion reactors, we could well be creating matters directly out of the waste energy of mining farms, which itself is used to record blockchain information at a sub-nuclear level, the ultimate amalgam of Bitcoin and Gold.
1) Waste energy and ultra-high frequency coherent light used by some hypothetical optical processor are very different things. One is waste and cannot do useful work, and the other is useful energy that can do work.
2) As I pointed out, virtual particles are not matter and cannot be usefully used for the storage of information, since they do not obey the mass-shell relation.
3) "the ultimate amalgam of Bitcoin and Gold" wat. Surely you don't imply your superlaser-powered photonic processors would be creating gold particles? Because that'd belie a rather poor grasp of the physics you've accused me of not understanding.
By the way, laser light at a frequency high enough to produce virtual particles would absolutely
wreck whatever kind of photonic metamaterial is responsible for the information processing.
This is cypherdoc's thread and I have long been used to rant whatever I have in mind here, with only vague connection to what's being discussed, sorry if it brings confusion.
Yes per the definition of waste energy to think they can be used to create matters is ridiculous, what I meant is more along the line of "still highly energetic photons after being used for calculation", and information recording would certainly not happen at pair production time, it has to be afterwards, and we haven't even started with the creation of protons and neutrons, which is completely another matter, in fact it would be silly if you choose to create subatomic particles yourself rather than using the protons that is already abundant in the Universe, the whole rant is actually a response to goldbug's claim that Bitcoin is not physical and thus have no real value, so the gold thing is completely metaphoric.
Solid metamaterials will be wrecked, but plasmas can support light-bending up to the desired energy level very well, and by the way, after the electron-pairs are created they are as real as the electrons in your bread and not virtual anymore. And stimulated emission would work just fine, you can use highly accelerated free electrons to produce coherent radiations, not just orbit electrons.
