I don't know much about the subject, but considering such a system will fundamentally change the world of computing... where will Unix fit in?
I try avoiding the subject.. mostly because I can't wrap my head around it. |

I honestly don't know what the current status is on quantum computing, but I do know this. If I am lucky, within my life time I might see 32-bit systems become like 16-bit ones are today among computer users. With how far away that will probably be, assuming I even have kids - maybe my great great grand kids will see quantum computers make the same headway that 64-bit systems are making now.
64-bit capable systems are everywhere, but at home how many copies of Windows XP/VISA do you see running x86-64 on store shelves? One of my friends threw out the 64-bit version of WinXP and Ubuntu some time ago, they just couldn't bare his gaming rig. I can just imagine what horror the change over to quantum computers will bring users, even NetBSD might take sometime to reach that level of portability, let along most peoples everyday software lol.

I really doubt it. Perhaps we'll see something TerryP said - QC being something like 64-bit systems today. Then again, you never know.

64-bit processors have existed since the 60's, only the introduction into the modern PC market was recent..
There is a lot of backwards compatibility though, for instance.. many 64-bit architectures are LP64, this means char, short, int in the C language are the same size as the x86 counterpart.. only long and pointers are 64-bits wide. Quantum computing, as I understand it.. is a fundamental redesign of computing... heck, it won't even be 1's and 0's anymore.. it'll be more like "maybe 1" or "maybe 0" or both. Software will change, porting seems unlikely... I don't want quantum computers in my life time. |

The move to QC will be nothing like the 32->64 bit transition.
Infact the move to 64 bit is quite painless. If you are running a 64 bit OS on intel/amd then you have the flexibility of running 32-bit software (at full speed with no performance penalty) or 64-bit software where needed. Software that doesn't require 64b capability can be expected to perform slightly worse if compiled as a 64b app and this holds true for other architectures too. The key point here is that 32b software can happily co-exist with 64b software on a 64-bit OS. Now, QC with its qbits and other jargon is beyond my grasp but I have a feeling that code for QC software will look nothing like what we have today and thats the scary bit. ![]() Last edited by ephemera; 14th October 2008 at 04:30 PM. |

Quantum computers will have high-level programming languages such as Python or Java, where you don't really need to worry about the underlying hardware.
Low level programming however, will be quite a different story.

Well, you sure can use your Lamborghini to go shopping at WalMart. Matter of ego.
Quantum desktops, ditto. Just define "desktop". I trust there won't be many desktops around in a couple of years.

If QC becomes the norm, qbits and an understanding of quantum superpositions will probably become your new bit twiddling buddies.

I would not like anything that represents a dumb terminal tied to a central M$ server, and they forcing you to pay monthly fees to "rent" their apps and access the data you produce with those apps and store in their cencorship-ridden servers to replace my beloved PC's and the OS's and apps I run on them and data I store on them.
P.D: I admit it, I'm quite frigtened of the mere though of that type of future ever happening. |

Maybe I'm crazy, but I'm willing to go out on a limb here and say that the next awesome leap forward in computing will be grey matter as a storage device.
In the end, humans are computers, and we could learn a lot about computer design by studying how we ourselves are designed. |

don't be limited to just electron movement in nerves
I remember few years ago I've read that (if i'm correct, Israel) scientists did experimet, that solved mathematical problem using DNA, the speed was incredible.... further experiments could make it possible to build organic computers.... |

I was looking for an article about that earlier today. I read it in ACM along with the quantum article...

Well, lacking the necessary knowledge to describe it in the same terms as a neurological specialist, and being the next closest domain specialist when it comes to my brain... I often speak of how my brain works, as if it was a OS kernel, for lack of a better choice of words :-P.
I think quantum computing on the desktop will probably happen long before 'organic' computers make their way to every bodies desktops. I would however like to see more average computer users to actually use some more gray matter for a change!!!

There are so many factors involved with bringing Quantum Computing to the desktop that it's likely not going to happen in our lifetime in any meaningful mass commercial way.
Not only are there issues of hardware design, but even if those were figured out, the scale of manufacturing required to bring down the pricepoint to where you would find these devices on your desk is so large that I think that's an insurmountable problem in the forseeable future. Then you have the software developers. Sure, you will have a few that can actually program in this new environment in a slightly meaningful way, but to port the existing worldwide libraries of software into QC seems a bit far-fetched, much less retrain mass numbers of developers to stop programming with 'traditional' techniques and move to QC programming. And given the edge that QC gives governments over people and corporations and other governments in areas like encryption and weapons testing simulations, its likely (to me) that they will want to not spread the wealth of QC to the masses for as long as they can help it. Do I fear it? Nope. Do I expect to ever sit down with a MacBook QC Pro in my lifetime? Nope.

Will we ever get it as a desktop? If you're working for the government, in cryptography, in a company with a technology budget large enough to buy a few small islands in the pacific, maybe. At a university ... maybe, depending on what you do. For home use? As much as I hope, which I suspect is responsibel for my "maybe," I doubt it. |
