In a typical quantum cryptography scheme, particles of light called photons are sent through the air, where the particles may be absorbed or their properties muddled.

Light is particles science calls photons, correct?

While many strategies are being pursued to enable quantum cryptography, one of the leading contenders is based on a phenomenon called photon entanglement.

This, on the other hand, was the advantage of the so - called photon mapping.

Physicists realized that light is not a wave exactly but rather a wavelike particle called a photon.

If one grants that it is photons that are primarily carriers of information, the question arises how images with their special «qualitative feels» could possibly result from what might be called one - way leaps across a category gap»; that is to say, how entities that belong to the category of the actual (as feelings surely must) can be caused by entities that belong to the category of the potential (for photons, as carriers of information, merely convey «meanings in potentia»).
