Quantum leap towards computer of the future

Breakthrough: an artist's impression of a phosphorus atom (a red sphere surrounded by a blue electron cloud) coupled to a silicon single-electron transistor (College of Fine Arts, The University of New South Wales: William Algar-Chuklin)
An Australian-led team of scientists have taken a big step forward in the race to develop a quantum computer.
Quantum computing relies on harnessing the laws of quantum physics, which includes laws that apply to particles smaller than an atom, in order to get a computer to carry out many calculations at the same time.
Previous research has focused on using light, or materials other than silicon, in their work on quantum computers.
But the team, led by engineers from the University of New South Wales and the University of Melbourne, have been examining the properties of electrons embedded in silicon, which is cheaper, better-understood, and forms the basis of most electronics today.
To build a quantum computer, researchers need to be able to write information to an electron, by changing its "spin state", and to read information, by measuring its spin.
In an article published today in Nature, the researchers say they have cracked the second part of this puzzle, by creating a device that measures the spin state of a single electron in a single phosphorus atom inside a block of silicon.
"What we have demonstrated in this Nature paper is the ability to read out when the electron is in some random state," said co-author Andrea Morello.
"The next thing is to prepare it in exactly the state we want it."
Dr Morello's co-author, Professor Andrew Dzurak, says after a decade of work it is a special moment.
"Quantum computers won't speed up all day-to-day computing," he said.
"But there are three areas where we know it will be much faster: cracking most modern forms of encryption; searching databases; and modelling atomic systems such as biological molecules and drugs."
Professor Andrew White of the University of Queensland, who was not part of the research, says it is an "outstanding result".
"The whole world is exploring technologies to build quantum computers," he said.
"The team have made the key advance of showing they can read out information from these spins in a single fast measurement that faithfully transmits the information."
"This opens up the road for silicon quantum computing."

And it's just a few years ago that they discovered the secret of splitting the beer atom! :D

Quantum leap towards computer of the future
By Rosanna Ryan
Sounds more a Quantum Lunch article, plenty of untangled sentences and quasi truths with plenty of mustard to fill it out. Not unusual faire for a ex-features hack with a lack of substantive knowledge.
Lets change the title, Lackluster leap to computer boredom. Today, scientists untangled the web of quantum computers by establishing that no matter how you cut it, quantum states and quantum entanglement are just a short sentence off an insanity plea.
Whether us mere mortals, can grasp that, each state is subject to the entanglement of any other or that Heisenberg was a Nazi, yet he is thrown a cue to appear every time someone thinks they actually understood the subject explains it all.
If Heisenberg was an uncertainty surely his mock science is too. Roll on Quantum computers, I'm certainly getting bored paying taxes to research it. Time to put up or shut up!

You have to give these nutty professor guys something to do, it help keep them off the streets and out the pubs where they can attack you ears with verbal diarrhea. :)
Having said that I notice your complaint about paying taxes to fund these guys, I'm not big on geography but isn't Nottingham in England ! or is the wicked sheriff still around gathering taxes and shipping them off to Oz, reckon you best go look for a certain Mr Hood in the woods to sort out your tax problems. :)

It never ceases to amaze me how people complain about the cost of scientific research whilst living lifestyles that rely upon it.

So now the real work begins.

Didn't you know Nottingham is the centre (English spelling) of known universe when it comes to quantumnessness. http://www.nottingham.ac.uk/News/ExpertiseGuide/Experts/F/ProfessorTomFoxon.aspx
I nerded that nugget from Google another supposed sucker of the spintronic revolution.

WOW... I'd hate to meet him in the local boozer... (help me ears are bleeding...) :)

Science fund away.....Voodoo Hoodoo research into the plainly silly no. (Bouddy loves quantum physics but I am agast at the cash cow post-cold fusion generation of re-re-researcherasses who predict 75% likelyhood of a quantum state being measured by a tea driven atomic vector plotter, think its progress)

Its like yesterday. Breaking news, someone managed to create a bit using one atom using a "electron microscope", as if any time soon someone will manage to condense an electron microscope and its chiller unit down to the size of a convenient pocket size Iphone.

Government funded research in most capitalist countries does little to advance our lifestyles. It mostly advances the scientists lifestyles. Most scientists are largely out for headlines for their next grant.
R+D in real commercial type companies does further our way of life.

The electron microscope only allows you to see what you are doing. The job itself was done with a "Tunneling Electron Micrograph".

It's about time they give up on that flying thing, too. It's contrary to common sense and complete rubbish. If God wanting us mucking about in His domain, He'd have built us a space elevator. Why do you think the lost tribes of Israel settled on the center of the earth?

There's not much in terms of technology we use and take for granted these days that wasn't originally developed by or with funding provided by NASA.
For-profit businesses employ scientists, too. Some of them are even allowed to--*gasp*--publish their research.

Rubbish! You've actually managed to annoy me with this statement. A grand unified theory is necessary for a true understanding of our world and the advances in this field come from government fuded sources. From the papermate pen and odour eaters to advances in aviation safety, all are derived from government funded space research. In fact NASA alone has filed over 6300 patents in the US and even produces a jounal (Spinoff) that highlights the diffusion of these patents into everyday items. Quantum research has resulted in more efficient fuels, batteries even improvements in the laser technologies used by optical drives. Do I need to go on, I could ram this point home but a google search on the benefits of government research would do just as well. Or try NASA and the Institute Of Physics own websites.
As for commercial ventures, they also give us intensive farming techniques for pigs that have resulted in devastation for many of the US fish stocks and lets not forget philidimide. Never loose sight of the fact that companies serve only to increase cash flow for shareholders, this brings us benefits at times but it also serves to pack our food with chemical crap and make drugs for fictitious mental illness among other ills.

God's domain (God.com) seems to belong to some Evangelical Christians. Quantum mechanics is, at it's heart and soul, completely and totally raving mad. It's absolute madness, if true, is a good argument for atheism...
-

LOL, you got that one in whilst I was still rant-typing. Beat me to it. As for the lost tribes, they only escaped to the centre of the earth in order to travel through the singularity present there and return home to Sirius.

Tripitaka, Touche!
Man, while reading this thread was watching the Richard Greene 'Adventures of Robin Hood', I found the combination rather amusing.... :)
At any rate, It'd be cool to check out a quantum computer... if they can ever get it to work.....
Hmm, I could think of a few codes I'd like to crack.... :evil:

Provided there is a grand unified and deep-pocketed tax payer base.
Sorry for that.
But really, I would imagine a researcher would be happy to do his/her work no matter who pays for it. Unifying the fund sources doesn't necessarily unify the work nor should it necessarily separate researchers into separate or partisan camps?
I don't have anything against NASA or patents that have been funded from government sources but I'm sure many good, useful inventions weren't funded this way.

As long as there is a ban on Microsoft making an OS for them otherwise they will be just 1% faster than an Intel i7 LOL

All this talk of Quantum computing is old hat. Long, long ago sometime way off in the far distant future quantum computing was surpassed by the hooking a really old and yellowing A1200 up to some brownian motion liquid and with the aid of an old copy of DiskSalv, the Amiga once again reigns supreme.
If you add the new Time Travel hardware now available from you local 24 hour convenience store, priced at only £999,999,999.95 (OS 3.x & USB only...) you can even travel back in time and inform everyone about some totally useless facts on what the future holds for the Amiga & computing...
Uh oh, just got an error number 103... help I'm stuck in 2010 and can't get back to the future, anyone know how to fix this problem, could it be my black matter powered floppy is failing, or does anyone have an old DeLorean DMC-12 I can borrow for a millenia or two !!!
(PS: Bill Gates & Microsoft were closed down in the year 2195, when it was discovered that he was in fact an alien lifeform from another dimension, who had used a stolen Amiga to travel back in time to con the world with a shoddy OS system he had stolen from the Borg..) :crazy:
-

Reverse the flow on the flux inhibitors and re-calibrate the Heisenberg compensator, then re-boot. If that fails you'll need to open up the ultinium inlets on the drive over a spatial rift (try Cardiff, Lowestoft or New Pitsligo).
Glad I could help and in case your wondering, I'm originally from Cestrus Omicron III.

Bugger... tried all that but no luck Im afraid, it just caused a temporal inversion loop in the space time continuum which let Mr Gates sneak back through and release the Windows phone that he stole from Apple.
Went to Cardiff once, but it was shut... :(
Oh well, guess I'll have to hang around in 2010 for a few more decades, until I can sort out this problem, now where my sonic screwdriver...
(PS: I hear it's nice on Cestrus Omicron III, this time of year...)

some brownian motion liquid
I had one of those last night, after making a rather hot curry.

nice so you've given us one of the very few very bright spots in government funded research (nasa) and a couple of the failures of commercial research. In governement research you just have to convince the powers that be that something needs to be studied. It doesn't have to have a point, it doesn't even have to any real application. So researchers go around looking for something to research just to have a job. Moochers is what some people call them.
In commercial R+D it has to have a point, it has to have an application (a way to improve life in some way) You don't see commercial R+D firms studying how much methane cows fart out. Or if greenhouse warming is occuring for decades, with no effort or metod of making a change. No commercial firms study ways to make things better.
I guess what it really comes down to is knowledge verses action. NASA found ways to make planes safer and more efficient. But it isn't NASA that does anything with that knowledge. Its the aircraft companies. And they can't just take that knowledge and make an airplane, they have to do huge amounts of R+D just to use any good idea NASA comes up with.
Much of the federal R+D that you will see outside NASA etc. is pork. Dr. Whatsisname knows a senator and convinces said senator that studying frog anuses is important because they might be getting smaller due to global warming. Senator gets others to go along with Frog Anus studies in exchange for his vote on their bills (more pork) and voilla Dr. Whatsisname gets a $250,000 grant to look up frogs tailpipes.
That is how much federal research grants go. If that money actually went to NASA we would see much more real, important science going on. NASA's budget has been cut almost every single year for decades.

I had one of those last night, after making a rather hot curry.
Vindaloo & brownian motion liquid... you cant beat it... :)
My Favorite Recipe To make the perfect Vindaloo... :)
Two Jars of Pataks Vindaloo Paste
One Large Onion
Fresh Chicken Breast
1 Large Green Pepper
1 Large Green Chili
1 Pair Asbestos Gloves.... :biglaugh:
(forget the instructions on the jar (two tablespoons) empty both jars in the pot and you've got the hottest Vindaloo you could ever want...) :cool:
-
Two jars is just far too much salt. A tablespoon of the stuff and a can of chopped tomatoes is much better. For heat, add as much chopped fresh naga chilli peppers as you can handle, or if you don't have any, as many drops of Blair's Jersey Death sauce as you can tolerate ;)
-
@KThunder
Scientific research is typically funded by governments, private organizations and commercial interests alike. Thank you for fitting a certain stereotype though :)

Nah, gotta be two jars or I can't taste it anymore, No one else I know can handle one of my curries, many have tried but all have failed... :)
On the subject of salt, in recent months the jar now say's 'contains 60% less salt', makes you wonder how much was in it to start with !!!
It's called traditional Scottish health food here... :roflmao:
-
It's not really of any interest to the home user. I guess it will fine tech for supercomputers though. They'll change from taking up a room in silicon to taking up a room in cooling equipment, but have a lot more power.
I'm most excited about AI, you can have real thinking computer opponents in games. And of course a robot butler.

Theory and application go hand in hand.
So researchers go around looking for something to research just to have a job. Moochers is what some people call them.
That's bulls**t, but there's a capitalist slant to that. It doesn't matter what the motivation is as long as someone profits from it.
In commercial R+D it has to have a point, it has to have an application (a way to improve life in some way)
Commercial research and development has to lead to profit. If companies could profit by developing and selling rainbow colored s**t, they would.
I guess what it really comes down to is knowledge verses action. NASA found ways to make planes safer and more efficient. But it isn't NASA that does anything with that knowledge. Its the aircraft companies. And they can't just take that knowledge and make an airplane, they have to do huge amounts of R+D just to use any good idea NASA comes up with.
The only reason those companies are willing to invest resources in such projects is because the risk is being assumed by the government. They have nothing to lose and everything to gain.
Much of the federal R+D that you will see outside NASA etc. is pork. Dr. Whatsisname knows a senator and convinces said senator that studying frog anuses is important because they might be getting smaller due to global warming.
"Pork" is subjective, but more research is funded by private money than you might think. The difference is scale. What the space race accomplished over a period of months or years, modern, private efforts won't achieve for years or decades.
EDIT:
That is how much federal research grants go. If that money actually went to NASA we would see much more real, important science going on. NASA's budget has been cut almost every single year for decades.
On this we agree. We're still riding the wave of Big Government Projects, though, e.g. the Internet and most of its core technologies. It won't be long, however, before things stagnate. Today's innovations are driven by profit and control.

A quick question, if I may, to all our fellow Amigan's across the pond... :)
I've noticed in numerous threads here, that our cousins the USA almost always seem to bring politics, government, corporations and all that stuff into a lot of their replys.
Just wondering is it so bad in the USA, that everyone over there is so disillusioned with every thing in life that you all feel the need to blame it on someone else.
My sister who lives in Portland Oregon has become like this, every time we talk on the phone it's all about, how it's too expensive to go to the doctors or dentists and the government, the greedy corporations and the homeless are all to blame...
I keep telling her, move back to Scotland then, cos here the minority that have to work for a living hardly ever complain, they're too busy working to keep the rest of us layabouts going in fags & booze...
Move to Scotland, the weathers crap, but the lifestyles easy... :biglaugh:
