A way to understand the huge and important advantages of DMF optical computing over the D-wave is to think of things this way:  Imagine the problems of building a D-wave into a computer brain that will allow robots to operate in outer space to build automated space facilities with regolith or agglomerated Martian sand. The D-wave must be kept at an extremely low temperature (NASA had great trouble just keeping a robot brain warm enough to survive on Mars one severe winter — and so you can imagine the energy involved with keeping the D-wave cool), and how can the D-wave tolerate the hard radiation of space or overcome the potential for decoherence so that it is always dependable in space? Logically, the D-wave cannot feasibly serve as a brain for a robot that is building architecture in space.

Whereas a DMF optical computer can tolerate hard radiation and will automatically work in a very wide range of temperatures and cannot suffer decoherence, and so a DMF optical computing brain can be inserted into robotics and afford them great intelligence and dexterity. Compared to what can be done with DMF, the progress with diamond optical computing is not great when working with electron spin in diamond (the supposed state-of-the-art method) , as you can see by this Wikipedia entry:

“In April 2012 a multinational team of researchers from the University of Southern California, Delft University of Technology, the Iowa State University of Science and Technology, and the University of California, Santa Barbara, constructed a two-qubit quantum computer on a crystal of diamond doped with some manner of impurity, that can easily be scaled up in size and functionality at room temperature. Two logical qubit directions of electron spin and nitrogen kernels spin were used. A system which formed an impulse of microwave radiation of certain duration and the form was developed for maintenance of protection against decoherence. By means of this computer Grover’s algorithm for four variants of search has generated the right answer from the first try in 95% of cases.[56]


Whereas. with DMF, all the defects necessary can be drawn with laser lithography, so that a whole circuit board is drawn (using a proton beam) right inside diamond film. With this system, one can even draw a circuit board that operates with electron flow (as with conventional computers) and couple it with a proton-beam drawn optical computing circuit board (using billions of light beams that crisscross each other without interfering to create tremendous computer power — and do so without any need for metal connectors). That way, the best of both computing types can be combined, and the micron-sized channels in DMF mean that the electron computer portion can be configured into a supercomputer.

Diamond overcomes one of the major problems of creating a quantum computer chip. The germane problem with conventional quantum computing is external influence. The smallest vibration can ruin the coherence of data. This in turn corrupts the calculations the quantum computer makes. Even cosmic rays from outer space that reach the Earth can cause the decoherence. Vibrations from nearby street traffic can cause decoherence. On the Moon, moonquakes vibrate the entire Moon and make it ring. But with optical quantum computing the problem does not exist. Diamond shields photons from interferences, so that data distortion is prevented.

But with the D-wave decoherence is a serious problem. As of Jan 9, 2014: “Choosing his words painstakingly in a phone interview, Lidar says the “time-to-solution” issue Troyer points to suggests that decoherence is a clear and growing threat to the D-Wave machine. He explains that although he has seen some encouraging results in the lab, “solving” D-Wave’s decoherence problem is “an extremely tall order and is likely to require substantial changes to the existing D-Wave design.”

In sum, I hope you can now begin to see why the DMF optical computing system is superior; its cost and manufacture will be reasonable, and there are no problems with decoherence. DMF can work as robotic brains for both macro and micron scale devices, and allow them to be wholly robotic in their DMF portions. DMF can advance electronics (so that electronics are noise free and not prone to failure in outer space from temperature extremes or hard radiation), and advance robotics and computing in ways that make creating virtually permanent facilities in space feasible. These industries (robotics, electronics, and computing) can also be advanced industrially with DMF on Earth to generate income for building in space, so that exponential growth off planet can be kick started sooner. Besides, with DMF, the satellite industry can be advanced so that satellites do not fail from severe solar flares.
