Isn't optical computing basically a scam? To achieve the same circuit density that we currently have with semiconductors, they would have to operate on photons

Isn't optical computing basically a scam? To achieve the same circuit density that we currently have with semiconductors, they would have to operate on photons with ~1nm wavelength, which is in the X-ray range.
- adastra22 11mo ago“2nm” transistors aren’t actually 2nm.
- meindnoch 11mo agoI didn't mention transistors. The de Broglie wavelength of an electron is 3 orders of magnitude smaller than the wavelength of a photon of the same energy. Period.
- watersb 11mo agoThe wavelength of an electron may be way smaller than the wavelength of a photon at the same energy... But do photons take up as much room as equivalent electrons? Seems like there's lots of tricks you can play, and we don't really know them all yet.
