- groo68, on 07/01/2008, -11/+143That's sort of the point, isn't it? I mean if it doesn't replace the pc what is it good for, and technically it won't kill the pc, it will replace x86 architecture and binary hardware, moving the pc to a new level.
- doskir, on 07/01/2008, -6/+103yes just like the PC killed the abacus
- Otto, on 07/01/2008, -8/+101Short answer: not anytime soon.
- trollick, on 07/01/2008, -6/+97I'm a Mac...
AND I'M A QC, BITCH! - xxMarka, on 07/01/2008, -6/+68if someone owned their own QC, it would be a PC, I guess
will it CHANGE the PC as we know it? probably. - ivosilva, on 07/01/2008, -2/+56100 years from now, someone's gonna dig up that article and is going to post it on some social/news site, and our great-great-great-grandsons are going to laugh the hell out of us....
- ssmith2k3, on 07/01/2008, -8/+56Yes, but only the 5 richest kings in Europe be able to buy one.
- Slade605, on 07/01/2008, -0/+41It's hard to find adequate drivers for an abacus these days.
- poidh, on 07/01/2008, -20/+61"fantastic possibilities - including teleportation"
That will never happen, since it involves the destruction of the individual and his or her recreation. - Ninnux, on 07/01/2008, -2/+38It would be a PQC. Everyone would need to mind their Ps and Qs. See?
- Bleahdom, on 07/01/2008, -5/+34Those people digging you down obviously don't have any idea wtf scientific teleportation theory involves.
- trollick, on 07/01/2008, -4/+31But Quantum computers will be killed by Magic computers which also COULD become a reality very soon.
- SonnyW, on 07/01/2008, -3/+29You're supposed to ask if you can play Crysis with it.
- inactive, on 07/01/2008, -1/+27Accurate answer: maybe, maybe not. You'll have to check on it.
- NiGHTSChao, on 07/01/2008, -3/+27At least I didn't say Halo :/
- NiGHTSChao, on 07/01/2008, -19/+39But can I still play Team Fortress 2?
- Pissoff, on 07/01/2008, -0/+18100 years? great-great-great-grand?
Glad to see public schools are doing well. - bjs3171, on 07/01/2008, -3/+21hmm? it was talking about teleporting information as opposed to sending it over wires. do you travel over wires?
- philipz78, on 07/01/2008, -0/+18A lot of teen pregnancy
- yaosio, on 07/01/2008, -1/+18Read the article. A scientist who has been working with quantum theory said that before he would have said that quantum computers would be of little use for home users, however, he now has the opinion that they would work as normal desktop computers. Even if it turns out he's wrong, any massive parallel task could still be helped with an quantum add-on card. Sort of like how GPUs don't do too great being general purpose processors, but they still exist.
- cgruber, on 07/01/2008, -0/+16Yes/No
- einrobstein, on 07/01/2008, -1/+17Doesn't everyone?
- JonTheGoose, on 07/01/2008, -1/+17Actually, a hundred years from now they'll be saying "You fool!! This article says nothing about how to stop the zombies!! This whole mission was in vain.....*crash!* Oh god they're coming through the windows!!! No please no NO...NOOOOO AAAAUUUUGH-"
- DifferentAngle, on 07/01/2008, -2/+17This article is completely misleading. Quantum computers perform certain operations very quickly, not all operations. Any algorithm that you can super-parallel can be made incredibly fast, but any serial algorithm is still going to be faster on a traditional CPU. Quantum computers are run by normal electronics, so even if the qubits could be operated on faster than a normal cpu can do operations (which they cant) there is still a normal electronics bottleneck. Your general purpose cpu is not going away, you're just going to have another ASIC on your motherboard - a qpu (quantum processing unit), which will be special purpose like a gpu or ppu.
- zephc, on 07/01/2008, -0/+14It's a computer, not a time machine.
- Culyt, on 07/01/2008, -1/+15It doesn't really matter if you are made from the same physical matter.
How much physical matter can I remove from you before you stop becoming you? What if I do a leg, all your limbs, your internal organs, eyes etc... You get left with a brain. Well what if we do that too, we replace one neuron at a time with an artificial one that operates the same and is in the same state as the original. At what point are you no longer you, at what point is the old you declared dead and a new being created. From your point of view you wouldn't even notice its happened if we did it right. How is doing it slowly one bit at a time any different from doing it all at once?
Well it already happens anyway.
Your body changes as you grow so physically your completely different.
The cells in your body replace themselves, so every 7 years of so your made from totally different matter anyway.
There are billions of tiny creatures that make you up, they operate with the complexities of cities inside your body each with specific tasks but have no idea or care of the overall you. In some ways your their god, you exist only as knowledge, information, your a meta-being, the cells are the actual physical things, you are guiding them through life so they can continue to live and at the end you pass on the genetic code of everyone's existence since they all exist in your DNA, which at about 750Mb fits on a CD.
The atoms in your body are in constant state of motion spinning and whizzing around, even if they are the same atoms, they are in totally different states every second.
In reality if I made a copy of you it would be every bit the same as the original. What happens if I can re-integrate the two you's so you get both experiences. If the combined you, both of them, or a new 3rd you.
What makes up 'you' is the patterns that are stored in your brain, and even then I think that the 'self' isn't a easy single thing, for instance you have a neo-cortex which is the conscious, smart part of you, then you have the more animal part of the brain. Some sub-conscious parts of your brain make decisions that your consciousness then explains to itself. If you like or hate an idea normally its not because of valid reasoning even if you think it is, its basic psychology. They tested it by disabling parts of the brain then asking the person why they where doing what they where doing and they would make completely ridiculousness excuses as to why.
Basicly you as a individual don't really exist, you just think you do.
The only major concern for me is if you keep doing it you will loose quality, like copying a copy of a VHS tape.
☢ - Bennessy, on 07/01/2008, -1/+15No, too process intensive.
- poidh, on 07/01/2008, -0/+12I dugg you for pointing out in that the state of the human brain is physical, not "mental". Everything is physical.
- inactive, on 07/01/2008, -0/+12The marketing circle jerk that will take place is already making me nauseous.
- Pittance, on 07/01/2008, -10/+21"But the world's foremost experts in the field are now revising their predictions and believe that we could see quantum computers within years."
yeah, like 20-50 at least. stupid ***** title and description. we aren't very close to quantum computing. - subterfuge, on 07/01/2008, -1/+12it will not replace the PC, at least not with the current quantum tech we currently have. most conventional computers are multiple-instruction, single-data computers, which means they can tackle many tasks in a row, but only one task at a time. quantum computers are single-instruction, multiple-data computers, meaning they can do one task at a time, but that task can be highly complex. the downside to MISD computers is that some tasks can require many repeated calculations, and the downside to SIMD computers is that each tasks requires the computer to be reset. the ideal computer will be multiple-instruction AND multiple data. but quantum computers will not replace traditional computers for a while because the only thing they are really good for is code- and password-breaking, and other complex tasks that you don't do repeatedly. (typing a letter, for instance, would take ages on a quantum computer)
- RealmDown, on 07/01/2008, -0/+11That's quite a leap.
- elnerdo, on 07/01/2008, -1/+11The practical application of teleportation is in space travel. It's very hard to communicate with a spaceship that's hundreds of light years away. Unless you can teleport the information.
(See: Ansible) - erichw1504, on 07/01/2008, -0/+9perhaps a PQC? Personal Quantum Computer.
- Meep3D, on 07/01/2008, -1/+10Ahh yes, that old chestnut. Original. Anything you can use to make yourself feel better for being an idiot I suppose.
- migshark, on 07/01/2008, -0/+9Technically the frozen state of our conscience could be copied and transferred over wires. Afterwards, a host interface for it is simply a matter of the correct structural architecture.
- ExRe, on 07/01/2008, -1/+10Teleportation will never happen, and if it ever would I'd never use it.
The only effective way to "teleport" somebody would be to copy their exact particle structure and re-create it somewhere else. Basically making a duplicate of you. Then they would destroy the original, so you'd be dead.
Copying inanimate objects or cloning food would be a good use of it if it ever becomes possible. - KMartSheriff, on 07/01/2008, -0/+9You're only adding to the suck.
- albinoMithos, on 07/01/2008, -1/+9Hey man I still use my abacus dammit!
- person425, on 07/01/2008, -0/+8Quantum circuits will never never replace computers as we know them the same way that physics accelerators, graphics cards, and fpgas will never replace computers.
Quantum computation is very good at solving certain problems very quickly, but it struggles at other problems. I think soon we will start seeing computers with specialized processing units for the various tasks one would want to do with a computer, and the QPU will be just another PCI card for people who want to do physics modeling, massive number crunching etc. - KMartSheriff, on 07/01/2008, -0/+8This joke was funny at one time, maybe...
- tylerjwilk, on 07/01/2008, -1/+9dugg for cleverness
- ausfahrt, on 07/01/2008, -6/+14Wow i can't believe that no one has asked if it will run that one game that every one seems to want to know if it will run on various computers and video cards.
- senae, on 07/01/2008, -0/+8Except that 20 years ago they did.
Now that we rely on computers so much expect quantum computing to catch on like wildfire...
Once they're, you know, invented. - RealmDown, on 07/01/2008, -5/+12Why? It's open system....
- poidh, on 07/01/2008, -1/+7When using the word "teleportation", the general inference is with teleporting humans.
I didn't read the full article but knew in advance that if it wasn't talking about teleporting humans then the article would be using the word in a sensationalist manner. This is the telegraph after all; although an entertaining paper, it does tend to go for the fake wow factor. - pinguz, on 07/01/2008, -0/+6I may or may not have dugg your comment
- inactive, on 07/01/2008, -1/+7What fascinates me about people cooing about the ability to break all codes with quantum computing (it if ever comes to a working device) is that you can use one to make unbreakable codes negating their argument.
It's the old 'irresistible force against the unmovable object' fallacy, one begets the other. - donkevin, on 07/01/2008, -0/+6Can't run it on full.
- RealmDown, on 07/01/2008, -0/+6....and maybe not....
