Quantum Camera On a Silicon Chip
stefanparvu14 writes "Physicists in Switzerland and California have developed a new type of camera capable of imaging quantum correlations between pairs of photons. The details are presented in the current issue of the open-access publication New Journal of Physics. Unlike a conventional camera with a CCD imager, this camera is composed of Single Photon Avalanche Diode (SPAD) pixels implemented on a high-performance CMOS chip. One of the authors has provided more background for the non-physicist. Apparently, it could be used to verify the existence of Bose-Einstein condensates that are now starting to be produced in new ways."
Because sometimes the camera is there ... and sometimes it isn't.
...to this page while interesting on its own, doesn't appear relevant to the article.

Notice to Sourceforge, Inc. management: Close down Slashdot, sell the domain to a squatter, and focus on your core competency: Sourceforge. It needs a lot of work.
Slashdot no longer serves a unique purpose. The forum is a mess of buggy AJAX, it is irrelevant, the editors have no talent, and the news sucks!
News for Nerds. Stuff That Matters. NOT!
It's not news, it's not written by journalists and it's not stuff that matters. The only true part about their tagline is that it's for nerds. Stupid ones. Ones who are probably wearing some lame t-shirt from ThinkGeek with a stupid expression like "All your haXoRz are belong to us."
This thread about the 2.4.18 kernel release is a typical Slashdot news item. Idiocy, misinformation, testosterone-poisoned posturing, technology punditry, arrogance, bad logic: just another day in Slashdot-land.
The classic exchange is one Slashdotter complaining about ACs (people posting as Anonymous Cowards, i.e., not registered) and another Slashdotter blasting him for being so stupid and then outlining the steps need to get a for-all-intents-and-purposes anonymous Hotmail account and registering on Slashdot with a bogus name.
Lame personalities
Some of the Slashdot people have personality cults which is weird because they are incredibly lame. Every single poll seems to have a reference to a character named CowboyNeal. One of the founders/editors, Rob Malda, goes by the handle CmdrTaco, and his posts are incredibly shallow and stupid (although admittedly not much more than those of the other editors).
Every Slashdot-hater will claim to have a particularly dark place in their hearts for a certain individual, but frankly, they're all about the same. I ran into them in the Linux pavilion of Comdex a couple of years ago and they're a truly sorry bunch of humans. Just more proof that if you had the choice to be smart or lucky, you're much better off being lucky.
The problem with online forums: Why Slashdot isn't different than the rest
Admittedly, Slashdot's lameness isn't unique. As a matter of fact, it's normal. The main problem with online communities is that they do not scale well. While engineers argue about whether or not MySQL-backed sites can handle significant traffic, etc., they are really missing the point. Even if the software can handle it, the community can't.
Throwing more hardware at it doesn't help the problem. Nor does throwing more software. Nor does throwing more moderation. Nor does adding big warning messages to "please search the archives before posting a question." People get tired of hearing the same old questions over and over. What was once a place where new and innovative discussions sprang up every day is now a place where the same ten questions get asked over and over. Many of the most valuable contributors are the first to leave, just like talented employees bailing out of a foundering corporation.
The only hope is to pick a topic that is so esoteric that growth is extremely limited. Splitting up a community into sub-communities is also a possibility, but one that doesn't always work. If done too late, the majority of the most valuable contributors will have already left. Splitting a big blob of noise will result in many little blobs of noise. If done too early, there might not be sufficient energy/critical mass to nurture the newly-founded subcommunities.
What makes FC different?
The, uh, community citizens at F---edCompany.com contribute about the same quality of knowledge as your average forum participant, but unlike Slashdotters, A.) they aren't as arrogant, B.) they all seem to realize where they're posting (i.e., after all, the website is called F---edCompany.com), and C.) Pud (the founder/editor) knows he's a lucky idiot.
The very worst part about online forums
For the newcomer, a vibrant, high-traffic online forum seems like the El Dorado of information. It's not. It's a Pandora's Box, but even worse. The biggest single probl
Doesn't this run into the small problem of:
"observing a quantum event changes that event"?
A Bose-Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero. Bosons are just elementary particles which obey Bose-Einstein statistics. Bose-Einstein statistics determine the statistical distribution of identical, indistinguishable bosons over the energy states in thermal equilibrium.
Confused yet? Me too.
This game will waste your life. Don't clicky!
So what is this? Like 10,000 mpx?
The abstract mentions "confirming the presence of true Bose-Einstein macroscopic coherence (BEC) of cavity exciton polaritons." Can somebody elucidate?

Who cares? Nothing made by Bose is any good anyway.
Would someone let me know when this product is available in the form of an X10 camera that will NEVER catch any naked girls in my house, spy on evil relatives, and see who dropped that toilet-clogger at my last party.

yeah, i mean, who needs lhc? a freakin' camera should be enough!
only problem, you'll get a photo 50% of the times.
Could people please let the word "quantum" be? If I post a comment "scientists discover that god is quantum!", will it be posted and commented? Please, let's be serious on science and post/comment things based on their relevance. Another bullshit title, just for laugh: "scientists discover that black holes have hair!" http://arxiv.org/abs/0901.0359 (notice the title of the paper:"Black hole hair removal")
SPAD afterpulsing is probably not an issue for this project because it's looking at photon pairs, so uncorrelated random events occurring on all the SPADs won't affect the detection... but will decrease the counting/processing rate by bogging down the electronics.
For measuring concurrent events, I would've thought TTS would be much more critical, and you can't get much better than MCP-PMTs (10-20ps these days?). Just wondering if the same detection could've been done with a multi-anode MCP, although if the sensor is CMOS tech, APDs would probably be easier to incorporate onto an ASIC / SoC.
bundaegi is good for you
The thing I want to know is, if I take a picture of a cat with this camera, will it disappear??
we finally get our Heisenberg compensator?
This post is LAW where prohibited by VOID. Prosecutors will be violated.
But would it make a click sound when you take a photo?
Well, that is soon to be the law - and I would hope that it would apply to ever camera including this one and the ones on the Hubble.
