Wow. The technology is not far fetched, but I'm interested in information that has not been provided. The cascading effect seems to hint at something else for the actual data stream. If you take the video literally, it shows one clean proton in and a ton of electron garbage out with little or no control over singularities, but are stuck with pluralarities for the end result of data (lots of worthless junk code caused by lots of excessive electron cascades).
However, I could see algorithms and formulaes being broken up and congruently run in multiple parallel within a chip or single-chip multi-processing (Multi-Core or Multi-CPU competition by a single photon-chip). On the energy side as described, only one particle (proton) is moved (energy consumption or cost) that then cascades multiple free energy particles (electrons), then the video fails to state how much free energy is actually produced (cascaded).
Between 2000 and 2003,
1. Bell Labs Switzerland trapped light in a silicon wafer at 15 microns and were working towards 9 microns. The best I could see from the sample wafer was a flashlight or night light that required no electricity or batteries at the time I became aware of and saw the wafer. I was curious as how it could be applied to microchips or as a true photo-chip processor or whatever type chip.
Obviously, it's impossible to turn off, but doesn't require anymore energy introduction or conversion, if they ever develop it. The only downside I could see is if the silicon wafer cracked - the end of that. Crystal polarity and photo polarity could be used as the means of data storage and transmission without having to allow the light to escape or without having to release the excited photons.
2. Two independent U.S. university groups trapped light within a 3 millimeter fiber optics section using 'super cooled sodium' in one university research group and 'warm rubidium' in the second university research group.
The protons were physically stopped within the optic fiber which is the first time light had ever been reduced to 0 MPH/KPH, where as in a cyclotron light could only be slowed to about 14 to 25 MPH (about the speed of a typical bicyclist) and sped up to 6 times the normal speed of light. Light must travel at 6 to 8 times the normal speed of light to escape the gravitational pull of a typical blackhole. The cyclotron experiments is an advent to future space research satellites, if they can figure out how to miniaturize the cyclotron (LOL).
The trapped light was easily and completely released with an introduction of a single proton. Both independent university research groups discovered that the protons contained in the trapped light automatically lined up into a dual binary system and estimated that the trapped light (protons) contained in the 3 millimeter segment of optical fiber could store well over 2.4+ kilometers of data.

Currently, all publicly available photo electronic technologies in use do not utilize the full potential of light, other than using pulses of light for data (comparable to morse code using a flashlight), or photo polarity with crystal polarity. Electron manipulation of crystal polarity is common such as with the Junction Transister. Crystals can also be crushed to release electrons, such as with crystal-electronic lighters, etcetera.
Electrons can also be released by bombarding a conductor, but that's generally high power with exception of naturally radioactive conductors. Millions of anti-matter (positive electrons) have been found to be created and released by bombarding gold (as small as 1 millimeter square) with a laze. A single low-power fractional second pulse laze shot at the gold created on average about 180,000 anti-matter particles per pulse. Not sure how useful anti-matter and electronic circuitry work well together at this time.
I guess IBM is not using this dual-binary aspect of light. Who knows what technology is actually integrated? I need more information please, aside from the troubleshooting video chart reliant on a audio narrative. 40 Gigabits sounds more like an intentional impedence.
I'm probably reading too much into the video, and it's probably not really a true photonic chip, but an electronic chip that uses photon bombardment of an array of photo-sensors [an element array of miniaturized plug-in photo-sensitive night lights].
Oh well.

Had my hopes up for the even better technology with the potential: no plugs and no batteries required.
