And where is a link to the paper?

This just in, Breaking news!

Folding@home cluster running on light cures death.

I am all for technological advances...keep 'em coming..

I'll beleive it when I see it. There are so many technologies out there I doubt more than a few of them will make it into mass production. Still, I wish them the best of luck.

Photonic hurdle = Fast as light computing?

Sign me up!

 

[dread_cthulhu]

Can I haz? Once this is implemented... it sounds like computers really will be all smoke and mirrors!

 

[dogman_1234]

More tech to put into computers...pretty soon, computer will run on black holes with a single hydrogen atom processor. I will be dead when that happens though.

This is still in the realm of applied physics, not "technology", so I'd hold your undue pessimism until later.

Yes I would like my motherboard to glow like commander Data's positronic brain when I open the case

What's the difference between a circuit and a transistor? Are they the same because they sure sound like they are the same thing. Any clarification anyone?

An electronic circuit is a collection of interconnected electronic elements. A transistor is one possible element. Or was this a troll?

Probably as a result of being sucked into your computer's black hole!

As for Troll, i dont know on the smaller parts of thought for said of the ideas, does make wonder. But to say to make more use of anything would incline additional, yes?

Of it though does bring to "light" many ideas of use to say at times, like that of lighted sources for use. And with as well is it more say "power" frinedly. And if so, What little more of use from what it normally would be have for anything of use?

Then on say the sack of more, what more of is better then more of off what more would be?

Otherwise sounds interesting and for wait on a avialible use to say on the idea, yes? Price outside of course, but still not at the sametime.

Otherwise something that does something with itself to be more or less of something that still wasnt much of something in some way, probably finds its fancy, or not, usually would imply dumb, but maybe for "strings" of articles then one finds some smarts?? Yes??

I have a passing knowledge of electronics, but the article just went right over my head... still, anything improving computing is, almost certainly, great news.

Hmm...

Light travels one direction... pattern reflected asymmetrically... reflected pattern travels from CPU to disco ball... disco party in room while gaming.

ujelly?

I agree, however photonic based comptuers wil totally make sense for some applications two words come to mind space exploration , one of the biggest hurdles to the space program is gettign newer tech that is reliable , and every thign i've read on photonic computing suggest it would take alot more punnishment than current transistor technologies.

Not a bad idea, as a thought the back scatter light can also be used to carry information. Like multi-plexing , using fractal mathmatics this light can be captured and processed back into binary data.

I believe, but don't quote me,that the issue before with back scatter was canceling out/distorting the data stream by changing the phase. The information in the system is probably in the back scatter and I imagine the closer the back scatter function is to random (and therefore the less information carried), the better the system works.

The barriers to space exploration (other than adequate funding) are in the short term a lack of Pu-238 (the only suitable nucleide) for the RTG's that power long range probes beyond practical solar power range, and, in the long term, cheap-which means reusable- ferry vehicles to orbit as well as better, perhaps more exotic engine technologies for faster and longer range travel so that probes can be sent more consistently and technological advance on earth can be maximized sooner (i.e. no 90's tech orbiting Jupiter in this decade). We desperately need to develop powerful and efficient designs that leverage the far greater energy storage of nuclear power for these applications. Computing solutions, as of right now, are perhaps the only non-barrier. Current technology is far more than powerful enough, can be made very energy efficient (especially compared to the other equipment on the mission), is resilient, and because it works 'in the background' is easy to shield from cosmic radiation. The sensitivity of the exposed sensor to cosmic radiation is far more of an engineering concern. Due to the specialized tasks (no or little multitasking, no rendering especially for probes) the computers aboard these missions probably need to be no more powerful than 1/10 of the processing power of an iPhone. Any legitimate number crunching analysis of the data can be done by supercomputers on earth once its beamed back.

edit: any information of the system in the back scatter probably represents potential interference and therefore data loss.

I hate the lack of an edit button. So hard to read in the little box b4 posting.

At my age, I frequently turn up the browser to 125% of original size. Have you tried that?

there has been talk of photonic processing from back in the '80s when I was a kid. The #1 idea was to help update tech for space missions because it was harder to interrupt than the magnetic storage they were using (which literally was wire around magnets. Now we are using much more advanced tech that is not as sensitive to such problems, plus redundancy which helps, plus they are finding different materials which are more resilient, as well as better shielding tech. I am afraid now light based processing is still a long way off for practical use, it will live long as an interconnect (thunderbolt was supposed to be this), but photonic processing is still a long long way off.

We take another step towards the future!

Oh no! I can just see someone's specially built case and system setup with a little disco ball hanging inside it and instead of an old disk drive on the front there is an 8-track player.
