A cavity containing a squeezed vacuum, developed at the California Institute of Tech in separate research. The University of Calgary and Tokyo Institute of Technology research uses a similar squeezed vaccum to store "less than nothing".  (Source: California Institute of Technology)
"Less than nothing" is the new zero

The world of quantum mechanics is filled with outlandish physical phenomena --  including everything from perpetual motion to teleportation.  Scientists have sought, in recent years, to exploit these phenomena to create the ultimate computing machine.  Such a computer, which would put even Intel or IBM's mightiest system to shame, holds the promise to solve certain types of very difficult, but very important problems. 

Scientists have made large advances including creating cables for quantum computers, developing quantum encryption techniques, and the development of the first commercial quantum computer by D-Wave, co-developed by NASA.  Much of the research into quantum computing involves using photons to store and convey information inside advanced computer systems.  However, light on an atomic scale behaves rather "spooky." 

On a silicon transistor scale, for the most part "on" or 1 means charged, and "off" or 0 means no charge.  On a quantum scale, on still means a charge, but "off" or absence of light still produces a lesser amount of atomic noise.  In other words, even if a photon is turned off, the quantum computer will still read a small amount of noise, disrupting measurements.

Scientists, after puzzling over this complex problem have come up with an outlandish solution -- creating a "squeezed vacuum" a space which has less than nothing, less noise than a space with no light.  Scientists managed to store and retrieve this "perfect dark" quantum zero.  The special vacuum is created by a laser beam directed through special crystals.  Squeezed vacuums have previously been created but not stored.  Typical uses are gravity wave detection. 

Teams of physicists at the University of Calgary and the Tokyo Institute of Technology independently demonstrated that a squeezed vacuum can be stored in a collection of rubidium atoms and retrieved when necessary.  The work appears in today's edition of the physics journal Physical Review Letters.  In it the researchers detail how they verified that the space remained squeezed when retrieved, compared to no light.

Alexander Lvovsky, professor in the Department of Physics and Astronomy, Canada Research Chair and leader of the University of Calgary's Quantum Information Technology research group, stated, "Memory for light has been a big challenge in physics for many years and I am very pleased we have been able to bring it one step further.  It is important not only for quantum computers, but may also provide new ways to make unbreakable codes for transmitting sensitive information."

The team's research followed Harvard-Smithsonian scientists' 2001 work that slowed light to a stop and physicist Alexander Kuzmich of the Georgia Institute of Technology's work, which led to a successful 2006 effort to store and retrieve a photon.  Kuzmich was enthusiastic about the new developments and said that the ability to squeeze space closer to an absolute zero in terms of noise promises to significantly aid in the development of quantum networks.  He marveled at the work and said of the progress, "It's a real technical achievement."

Lvovsky’s team next hopes to develop storage methods for more complex forms of light, such as entangled light, which can lead to exotic new uses and improvements in quantum computing.

i think it's excellent how DT covers this cutting edge science. i will admit i understand very little of it so perhaps a lil 'dumbing down' should be looked into.

but all the same it's fantastic. do more DT! ^__^

Exactly, it is dumbed down. And it's still so new, no one even gets it. So what's the point of reporting something like that? I'll admit, I like how it is centered around technology possibilities, but it is still too new for many of us to appreciate.

I just don't understand why not a single one of these is ever mentioned in any TV news station.

Let's just forget, for a second, that 99.9% of the population will never have heard the world 'quantum' before and that the first thing sub zero brings into their mind is Pepsi Zero.

Oh they have surely heard the word quantum, but wouldn't have the faintest of ideas what the actual physics term means. Instead, they hear words like 'quantum' used in all manners of bullshit product marketing having nothing to do with reality.

It's actually very sad and pathetic how bad the level of public scientific literacy is in the USA. At the same time I feel incredibly angry and frustrated that there is not more real focus on the problem. Instead, the population stays incredibly stupid and ignorant. Oh how the empire is crumbling....

Generally speaking I agree that kids are socially promoted out of high school despite barely being able to read in some cases, but.. seriously.. Quantum physics needn't be taught in high school, or for the vast majority of college majors. That crosses the line in to specialized information that 99% of us will never need to know, will never find a practical use for, and will never care about except, potentially, out of curiosity. For those people there is Discovery Channel -- though I've slowly watched channels like Discovery get dumbed down over the years.

As an aside, I just read the graduation statistics for Detroit area high schools again today. My god. Detroit needs to be kicked out of the nation, perhaps given to Canada. Maybe just used for nuclear testing. It's a third world country. It's worse than many third world countries. If one read articles about it and replaced "Detroit" with "Zimbabwe", one would just nod their head and say "no surprise."

Eh? Your history is a bit off. Spartacus was a Roman slave, the leader of history's most famous slave revolt. You're thinking of the Spartans, who were several centuries earlier and several hundred miles away.

I believe the parent was trying to imply that Spartacus was named after the Spartans. This is a reasonable conjecture given the similarity of the names, however, probably not the case as Spartan is the Anglicized version of the Greek name, while Spartacus was actual name of the individual.

You really are reading too much into it. It's a name. So I assume you have a misty aura filled with "dingos"? And besides, Spartacus was a person, not a people.

And still there is no commercial product related to Q.C.

One more stepping stone on the way to quantum entanglement, quantum teleportation, quantum logic gates ...

The fact that scientists can store and retrieve "nothing" means we've successfully found a way to create a binary computer on the sub atomic scale.

The smallest practical size we can store a one and a zero is a few nanometers via exotic memory structures. The smallest experimental size we could store binary one and zero are a few atoms. With this, we're talking about storing binary one and zero on sub atomic scales.

Interestingly, this sort of debunks Rudy Rucker's thoughts on singularity: that we could not simulate "virtual" reality because it takes many atoms to simulate reality as it would to replicate it. Not true when we can store information on the sub atomic scale.

No they didn't. =) Developer RARE and publisher Microsoft Game Studios were all over it back in 2005 when they released Perfect Dark Zero for the XBOX360. =)

Who knew MS could make less than nothing???

LMAO

Seriously though...great article. My brother is getting his PhD. in high energy physics, so he's always filling my head with this futuristic mumbo jumbo.

Kristopher, it's nice to be optimistic but this isn't going to happen.

You know every few weeks, for the last two decades or so I've been an adult, there's an article in the paper that claims researchers have all but cured cancer. Yet Patrick Swayze's still gonna die.

It's kinda the same thing with quantum computing, you can bury me in articles saying it's just around the corner, buit I've been reading those for the last decade. It's kinda put up or shut up time now.

Honestly I dont think quantum computers are possible. And I even have my doubts whether quantum physics is a reality. That's just my opinion. My opinion could be proved wrong (maybe) by a true quantum computer becoming reality. But since that never seems to happen, I kinda suspect I'm right.

There are working quantum computers already. It's just that they are of only a few qubit stage which doesn't do much useful right now.

It's like the early conventional computers which has only a few transistors.

As posted by others, we already have quantum computers -- they're just only capable of 16 qubits or less.

Quantum mechanics is not a believe or disbelieve thing, though Einstein himself believed the odd things that occur on the subatomic could be explained away with classical physics. Of course, if those odd things didn't occur, we wouldn't have a lot of neat stuff like the laser.

http://en.wikipedia.org/wiki/Introduction_to_quant...

But whether you want to say that quantum mechanics doesn't make sense, or that it's not possible, the effects are still measurable and exploitable. And this has been demonstrated with people who've designed rudimentary quantum computers -- D-Wave.
