To be honest, I am not totally clear on what a photon actually is. I first heard about photons as a kid watching Star Trek. They were a type of torpedo, right? Well, in the real world I have never bumped into an actual photon. I do remember from somewhere that photons are packets of light. Hmmm … though it is a bit difficult to visualize light arriving at my eyeballs in packets. Is it gift wrapped as well? Wikipedia offers this helpful insight
… a photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force.
It is “the quantum of light”. Right. So … what the hell is a “quantum”? Back to Wikipedia
… a quantum (plural: quanta) is the minimum amount of any physical entity involved in an interaction.
Much more clear …. errr … I think. Photons are the minimum amounts of the physical entity in light? I guess that is right. With this now clear, consider what a few clever German scientists have just done
they have built the very first, elementary quantum network comprised of a pair of entangled atoms that transmit information to each other via single photons.
Dr. Stephan Ritter, added, “We were able to prove that the quantum states can be transferred much better than possible with any classical network.”
Getting to the point, it seems that we are a step closer to harnessing the potential of quantum computing. Ok. And what will quantum computing deliver to us. Errr … you know. More capacity, dude. A lot more capacity to do complicated stuff. Like my taxes.
