Quantum Telecloning

February 18th, 2006 | researchmaterial

The first experimental demonstration of quantum telecloning has been achieved by scientists at the University of Tokyo, the Japan Science and Technology Agency, and the University of York.

Telecloning combines cloning (or copying) with teleportation (i.e., disembodied transport).

The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement – multipartite entanglement.

Professor Sam Braunstein, of the Department of Computer Science at York, said: “Quantum mechanics allows us to do things which we previously thought were impossible. In 1998, I was involved in an experiment in America which was one of the first for quantum teleportation in which we transmitted a beam of light without it crossing the physical medium in between.

“This new experiment is an extension of that work. Whether it will change the world for individuals or is just of use to governments or big companies is hard to say. Any new protocol is like a new-born baby and it has to develop, but we know this one could be used to tap cryptographic channels. Quantum cryptographic protocols are so secure that they can not only discover tapping but also where and how much information is leaking out. Now, using telecloning, the identity and location of the eavesdropper can be concealed…”

  1. So, this means we can now make our own evil twin?
    ‘Bout damned time!

  2. Telepresence, and so forth. “Virtual Light” cycle

  3. I am so going to California to interview the Smiler’s wife. How come everything you write about happens eventually??? Can you predict me a larger wang?

  4. Didn’t you write this concept into Transmetropolitan, when Spider went to California “incognito” to visit the PResident’s wife?
    Oh Shit! I’m a fuckin’ fanboy! Just shoot me now……

  5. Isn’t this a little bit of blame-shifting as well? It doesn’t matter if it was predictable or not, or if the intentions by terrorist are known, because of the security failures on that day that would have prevented even a simple assault on one of those planes. If the Saudi’s had been caught going through the airports we’d be saying “well that’s why we have these measures”.

  6. fuck! stupid hand eye co-ordination screws me again

PauseTalk Tonight

Jean Snow - 05 Sep 10

Just your friendly neighborly reminder that this month’s PauseTalk (Vol. 44) happens tonight (September 6) at Cafe Pause, with the usual start time of 20:00 (and the cafe reserved from 19:30). As previously mentioned, I’ll bring out the magazines from last month’s SNOW Magazine Cafe, for anyone who didn’t get at chance to check out the event.

Wired Type Missteps

Jean Snow - 05 Sep 10

Wired on iPad

Just over a week ago the latest issue of Wired (September 2010) was released for iPad, and as I’ve done for all issues released for the device so far, I immediately bought it. Yes, despite the less-than-perfect way they’ve handled the digital conversion of the magazine, I’ve been enjoying the magazine, not only because of its nice price — for us Tokyo expats that is, although I still want an even cheaper subscription option — but also because I like the way it reads, and the way the material is presented (and those videos have been quite good too).

BUT, I was pretty surprised at some rather ridiculous flubs in the latest issue, both cases tied to the use of type. First example, pictured above, is an entire story — which also happens to be part of the issue’s cover story, “The Web is Dead,” which means it’s long — presented as white text on a red background. Really? Did anyone at Wired actually try reading the article after it was set in those colors? My eyes were practically in tears by the time I got to the end.

Next up was the use of type too tiny to read. The image above shows said article in landscape mode, and that “Buried” piece is where you encounter the problem — interestingly (if that’s the right word) enough, if you change it to portrait mode, it’s the page’s other article that becomes barely readable.

The big issue here is that these problems are tied to the fact that you can’t change type size in the magazine. So far it hasn’t been an issue for me because all previously issues were formatted in a way that made all text very readable on the iPad screen. I can appreciate that adjustable type size would ruin layouts, and I do like the layouts we’re offered in the magazine, but you can’t sacrifice readability just to make sure a column fits somewhere, or to attain a certain aesthetic (in the case of white type on red).

IT?S FUSTY IN HERE!

William Gibson - 05 Sep 10

As the London Times recently said of my living room, though you probably didn’t see that, as it’s behind their subscription wall. Had to check the definition. Hope they meant more “markedly old-fashioned” than “rotten”.

Starting tomorrow on the 36-day pre-Canadian leg of the Zero History tour. US and UK schedules are behind the button on this site’s front page. The subsequent Canadian dates (all in October, save for Nov 1 in Victoria BC) are behind the modest blue link on that schedule page.

Have not been blogging for quite a while, hence the fustiness, due mainly to the sublime ease of Twitter, whereon I am @GreatDismal and quite annoyingly posty.

Hope to get a bit of a breeze through here, with the constant traveling and all.

Sunday Supplemental: Aqua Team Hunger Fortress 2

Ectoplasmosis - 05 Sep 10

One of the more successful Team Fortress 2 video mini-memes is the Dr. Weird dub. With audio taken from animated shorts preceding episodes of the show Aqua Teen Hunger Force, the new animations (done with TF2 character models in Source Filmmaker) are short, simple, and funny. I post this as an introductory demonstration of the versatility of the game assets, and the ingenuity of the fan community. Enjoy.

Marcel the Shell With Shoes On

Coilhouse - 04 Sep 10

An animated short of MAXIMUM MEMEWORTHY ADORABLENESS, directed by Dean Fleischer-Camp. (“I am a director and an editor. And I literally got a college degree in making movies! You believe that? A COLLEGE DEGREE. College for movies? Hah! Can you beat it? I don’t think so– movies are the best!”) He is made of awesome. Go check out his website RITE NAO.

Marcel the Shell is voiced (“untreated and unenhanced”) by Jenny Slate– yes, the very same Jenny who dropped an F-Bomb during the live taping of her SNL debut. Prepare to squee your pants.

Katy Perry's Illuminati, MK-Ultra Commercial

jwz - 04 Sep 10

The Vigilant Citizen is one of the world's finest blogs.

This commercial intended for German television has it all: checkerboard patterns everywhere, transhumanism, deshumanization, mind control, alter-personalities, Marilyn Monroe (the original Monarch sex kitten), the colors white, black and red, etc.

"We love to entertain you". In other words, this is the kind the stuff that is supposed to entertain you.

Oh, it does. It does.

Prepare Thyself For? THE EXORSISTER!

Coilhouse - 04 Sep 10

Holy balls, kids. HOLY. BALLS.

These are stills from a clip of one seriously wackypants “Japanese punk rock Exorcist homage” called (appropriately enough) The Exorsister. It comes to us courtesy of the ever-terrifying and wondrous Weird Shit Magnet that is Dogmeat, who says “I’m laughing, because this is one clip where even I ask myself ‘Where do you get these?’ Stick around for the octopus attack… as if you would turn this off!”

Definitely not safe for work. Click the collection of stills above… IF YOUR DARE.

mixtape 093

jwz - 04 Sep 10

Please enjoy jwz mixtape 093.

Some of these videos don't play, because all extant copies on Youtube are marked "embedding disabled". I even tried re-uploading them, and the fabulously evil content-ID system re-fucked the new copies too. So, the copyright holders would rather you not become familiar with the work of the artists whom they purportedly represent. Oh well.
