Not sure what this means. De Broglie waves are defined for matter (mass is required). While photons have relativistic mass, this isn't the same thing.

- LoganDark 3y ago"Information carrier" means the actual medium the light is travelling through, doesn't it? Which has to be matter of some sort.
- orlp 3y agoLast time I checked the sun transfers its light through the vacuum of space to us.
- glitchc 3y agoIndeed, as orlp mentioned, light is self-propagating and does not require a medium. This is broadly true for all EM waves.
- Dylan16807 3y agoWe're talking about a CPU, not light traveling in a straight line forever.
- goatlover 3y agoWhy isn't the EM field the medium? Or even spacetime?
- aj7 3y agoYou are confusing geometry, and the excitation traveling through that geometry.
- aj7 3y agoBut it needs SPACE, on the order of a few um minimum, that cannot be occupied by other devices.
- aj7 3y agoThe deBroglie wavelength of the photon IS its wavelength. That’s why it can’t squeeze into nm features and optical waveguides are still not used on-chip, after 35 years of effort.
