Thanks for these thoughts. To my mind there needs to be some sort of machine interface with operations that can be called. It may be quite different to binary operations mapped to binary architectures yet be more adept certain problems and more like the more or less abandoned concepts of analogue computing.
I was reminded of when Jim Brown said he made use of IBM vector processor but when I discussed optimization problems with him he did not seem to have made special provision for problems that were not confined to integer or rational numbers - and yes the travelling salesman type problems are the ones they are first trying to map to this quantum machine because they get very large very quickly. I know its early days but they are scaling up fast and a high level language would a great thing to interface with such a machine. I think the quantum computers will take advantage of technology using light rather than electrons but the light technology can be used in binary architecture machines directly. Photonic chips — devices that use light beams instead of electrons use a new type of ultrasmall laser that could bring optical communications onto computer chips, breaking a bottleneck that limits computing speed. (a vertical-cavity surface-emitting laser (VCSEL) shines with a wavelength of 1550 nanometers, optical computer - move data using light instead of electricity). There is an Australian team that was the first in the world to have detected the spin, or quantum state, of a single atom using a combined optical and electrical approach: Read more at: http://phys.org/news/2013-05-quantum-internet-combined-optical-electrical.html#jCp 1 quibit quantum computer 2003 and growing faster than Moore’s Law - by 2012 - 200 quibits IBM and Sun Microsystems'new supercomputers have broken the "petaflop" speed barrier, (theInternational Supercomputer Conference in Dresden, Germany.) A petaflop equals one quadrillionfloating point operations per second, or 100,000 times fasterthan a home computer. D-Wave quantum computer matched the tenth ranked supercomputer for speed at 420 GFlops. 1.5 petaFlops preliminary tests on the sixth Vesuvius chip (having 503 good qubits), and is finding performance figures of about 5 petaFlops Donna Y [email protected] On 2013-10-12, at 2:58 PM, Robert Bernecky <[email protected]> wrote: > I'm also looking for that hardware reference manual. > Until then, I'm not going to say anything more on this. > > Bob > > On 13-10-12 02:43 PM, Raul Miller wrote: >> That is my understanding also.
