Anybody else remember an old sci-fi story about a man who sold "slow glass" that had a three-year delay?

NotARocketScientist: lightbulbs store light?

Yeah.  Didn't you know?  Car engines store power, ovens store heat, and light bulbs store light.  Duh.  Study it out.

WhippingBoy: Awesome. I've been storing my light in old paint cans under the stairs; this looks to be more efficient.

I've been keeping mine under a bushel.

This isn't just storing light - that's been done to death. This is about storing the coherent state of a photon without breaking down its probability wavefunction.

That is to say, if you were to do a quantum calculation using two photons, you don't want to lose the result by observing the resulting photon destructively. You want to be able to store the probability waveform in memory much like multiple bits are stored now using electrons.

Having now attempted to read the article, I have no idea what the end result of this technology is.  Anyone able to dumb it down for me?
