Air Force creates solid-state quantum interferometer glass, quantum computing in mind

Interferometry is a technique where electromagnetic waves are superimposed to extract data from the wave itself. Using an interferometer is a device that does the job, refracting and reflecting photons, for example, to analyze the wave. The issue is that these apparatuses are delicate to say the least. Constant recalibration is needed. Interferometers are often used as a way to carry out quantum processing, where the output of one is the input of another.
 
Jonathan MacDonald and his team from the Air Force Research Laboratory in Rome New York, working alone with Cornell University, have developed a way to make interferometers more solid-state. Optigrate, common Holograms, interferometers are embedded in glass creating a high resistance to environmental changes. Which eliminates the need for calibration. MacDonald stated that this tech could perform quantum teleportation and CNOT logic.
 
Unfortunately, the quantum glass is not reprogrammable. Each pane would be crafted to perform a single operation. If nothing else, the tech will speed up experimentation in quantum research.
Read more in the "Quantum Computing in a Piece of Glass" white paper.
 
I think the Air Force should look at the recent quantum IC created by the University of Bristol, where the photon manipulation is reprogrammable.

    An interesting idea, but as I stated, my knowledge is a few decades old.  I am sure there are many new photonic engineers who are much more in tune with the current technology.

     

    While I probably could not help much, I can see many potentials for the technology based upon some of the programs I used to work on.

    Like I posted earlier, keep an eye on this one.  It could soon get interesting.

    Dab,

     

    Every consider consulting in the quantum research department? That is, if you have extensive experience with the tech.

  • I worked on some interferometer fringe analysis devices back in the 1980's.  If they have improved the optics and combined them with new image processing algoritims, these devices could yeild some very interesting devices.

    I can see a lot of the technology that was not available then, coming to fruition in recent years.  They might actually begin to get optical computing devices practical enough to use.

     

    Definitely need to keep an eye on this research.
