Quantum Information Can be Negative
nerdlygirl writes "In a development that would probably even puzzle Claude Shannon,
information can be negative -- at least when the information is quantum.
The discovery, by
Horodecki, Oppenheim, and Winter, appears in the
current edition of the leading journal Nature.
If I tell you negative information, you'll know less. Apparently, researchers hope to use this to gain deeper insights into phenomena such as quantum teleportation and computation, as well as the very structure of the quantum world. More details can be found here and
here
A popular account of the article can be found on Oppenheim's
homepage, and a free version of the article can be found in the arxiv for those of us
without subscriptions to Nature."
Karl Rove has known this for years.
I have nothing to hide. So, why are you spying on me?
No it can't.
Initially, I believed that negative information was an abstract math concept, but after a significant amount of additional study I've determined rather conclusively that it exists in our frame of reference and that the effects are actually easy to detect. The trick is to *locate* some of this negative information. Fortunately, I've managed to work that out as well -- I'm not publishing for a few months yet, but I figure I'm far enough along to spill some of the beans:
Experiencing negative inforamtion is all about occupying a point in space and time which intersects with the negative information stream. This was initially tricky, but through months of tireless research I've worked out the optimal conditions: I find that your best chance of encountering it is roughly around 1 AM when you're at the bar with your friends after a long night of drinking and one of them says something along the lines of, "Awright! Time for some shots!"
Bang! Negative information. What happened after that? How did I get home? All lost in the quantum flow, never to be accurately described by anyone involved (except, occasionally and for reasons I still haven't managed to factor into my equations, the bouncer and the police). I assume the headaches and liver damage are just a nominal side effect.
Every year during my review, I just pray the words "slashdot.org" aren't mentioned.
it was negative information so I forgot how to get my socks in the dirty clothes.
After trying to read those articles, I do feel like I know less.
Forget the whales - save the babies.
Of course negative information is cool, but it would be even cooler if you could combine negative information and positive information to produce a huge explosion.

I think you've hit the lower limit already....
(-2)+(-3)=+1
You have obviously received a lot of negative information before you started writing this 'math'.
No sig today.
All this time I wondered how so many people could be so stupid as to believe the mountains of bullshit pushed by the creationist movement, and this explains it!
As information regarding the field of biology -- specifically in the study of evolution -- increases, a balance must be made. As a result, the increase of information in biology causes a reaction of an equal increase of negative information with respect to the creationist movement. The more biologists figure out and the more knowledgable experts become, the dumber and more gullible the general populace must become to balance the information flow out.
STOP MISUSING APOSTROPHES, YOU MORONS!!!
Depends on what you're doing. (-2)+(-3)=+1 is Slashdot Moderator Math, which has no basis in either reality or fantasy and transmits no useful information whatsoever.

The Fine Article doesn't mention one exciting development in the field of information theory, related to negative information, which may one day tie it to Vacuum Energy or Zero Point physics in a grand unified theory that, once we come to understand it, could form the basis of a star drive to power star ships.
It seems that virtual particles of antimatter and exotic particles of normal matter that spontaneously emerge from the void, and then disappear without interacting with anything. [1] The theoretical potential of tapping this particle flux has brought vacuum energy to the fore of research by the NSA into Quantum Information Theory.
Experiments conducted by the NSA and the DOE on large data samples gathered in large bureaucracies (both public and private) indicate that Microsoft Word Documents are effective containers for Negative Information, which hitherto had been considered a transient phenomenon, almost impossible to store given our current understanding of physics. The phenomenon of massive amounts of stored negative informisinformation, as it turns out, makes the typical corporate or government intranet much more resiliant to cyber terrorist attack than previously predicted -- nearly as resiliant as the typical government organization to a FOIA request today, for comparison.
It is expected that once we understand the characteristics of MS Word Documents which allow them to efficiently store negative information in a stable form, Quantum Physicists and Information Theorists should be able to get together, perhaps over a nice hot cup of tea, and stitch the two branches together, getting us one step closer to faster than light travel, finally bringing the stars within reach -- except it won't really be FTL, it will be something that we don't presently understand.

Only the humor-impaired need read this bootnote.
[1]Yes, I see the grammar error. I've intentionally borrowed a pattern, common in conspiracy theory writing, of constructing a complex sentence, perhaps full of objects, perhaps full of verbs, perhaps full of nouns, on the theory that it might amuse, whereas it normally serves to confuse, as sometimes subjects or verbs may go missing. Oops I did it again! Or did I?
[2]Yes, I realize I mention antimatter only in the title, and not in the text.
[3]Yes, I realize there are 3 bootnotes, not a single bootnote as referenced above.
[4]Yes, I realize that only 2 of the bootnotes are indicated by reference numbers in the text. (Absurd bootnotes are also common in conspiracy theorist writings.)
If you mod me down, I shall become more powerful than you could possibly imagine.
Utter ignorance is the total lack of information, or the complete absence of knowledge. We all know that nowledge is power, and power is force over time. Time is money, so knowledge is force over money. Ergo, someone who is ignorant has no force over money, which is certainly ironic given that the Nature article is entitled "Quantum Information: Putting certainty in the bank". Yes, poor people are easy to make fun of even in quantum states (which were formally known as blue states until the manic depressives complained about trademark infringement).
