The AI on the horizon looks more like Amazon Web Services—cheap, reliable, industrial-grade digital smartness running behind everything, and almost invisible except when it blinks off. This is a big deal, and now it's here.
Physicists have teleported a light particle 15 miles (25 kilometers), making it the farthest quantum teleportation yet.
Advances in quantum teleportation could lead to better Internet and communication security, and get scientists closer to developing quantum computers. About five years ago, researchers could only teleport quantum information, such as which direction a particle is spinning, across a few meters. Now, they can beam that information across several miles.
Physicists can't instantly transport matter, but they can instantly transport information through quantum teleportation. This works thanks to a bizarre quantum mechanics property called entanglement. Quantum entanglement happens when two subatomic particles stay connected no matter how far apart they are. When one particle is disturbed, it instantly affects the entangled partner. It's impossible to tell the state of either particle until one is directly measured, but measuring one particle instantly determines the state of its partner.
In the new, record-breaking experiment, researchers from the University of Geneva, NASA's Jet Propulsion Laboratory and the National Institute of Standards and Technology used a superfast laser to pump out photons. Every once in a while, two photons would become entangled. Once the researchers had an entangled pair, they sent one down the optical fiber and stored the other in a crystal at the end of the cable. Then, the researchers shot a third particle of light at the photon traveling down the cable. When the two collided, they obliterated each other.
Quantum information has already been transferred dozens of miles, but this is the farthest it's been transported using an optical fiber, and then recorded and stored at the other end. Other quantum teleportation experiments that beamed photons farther used lasers instead of optical fibers to send the information. But unlike the laser method, the optical-fiber method could eventually be used to develop technology like quantum computers that are capable of extremely fast computing, or quantum cryptography that could make secure communication possible.
Computers might soon become more intelligent than us. Some of the best brains in Silicon Valley are now trying to work out what happens next.
Nate Soares, a former Google engineer, is weighing up the chances of success for the project he is working on. He puts them at only about 5 per cent. But the odds he is calculating aren’t for some new smartphone app. Instead, Soares is talking about something much more arresting: whether programmers like him will be able to save mankind from extinction at the hands of its own most powerful creation.
The object of concern – both for him and the Machine Intelligence Research Institute (Miri), whose ofﬁces these are – is artiﬁcial intelligence (AI). Super-smart machines with malicious intent are a staple of science ﬁction, from the soft-spoken Hal 9000 to the scarily violent Skynet. But the AI that people like Soares believe is coming mankind’s way, very probably before the end of this century, would be much worse.
Besides Soares, there are probably only four computer scientists in the world currently working on how to programme the super-smart machines of the not-too-distant future to make sure AI remains “friendly”, says Luke Muehlhauser, Miri’s director. It isn’t unusual to hear people express big thoughts about the future in Silicon Valley these days – though most of the technology visions are much more benign. It sometimes sounds as if every entrepreneur, however trivial the start-up, has taken a leaf from Google’s mission statement and is out to “make the world a better place”.
Warnings have lately grown louder. Astrophysicist Stephen Hawking, writing earlier this year, said that AI would be “the biggest event in human history”. But he added: “Unfortunately, it might also be the last.”
Elon Musk – whose successes with electric cars (through Tesla Motors) and private space flight (SpaceX) have elevated him to almost superhero status in Silicon Valley – has also spoken up. Several weeks ago, he advised his nearly 1.2 million Twitter followers to read Superintelligence, a book about the dangers of AI, which has made him think the technology is “potentially more dangerous than nukes”. Mankind, as Musk sees it, might be like a computer program whose usefulness ends once it has started up a more complex piece of software. “Hope we’re not just the biological boot loader for digital superintelligence,” he tweeted. “Unfortunately, that is increasingly probable.”
Today the collaboration for the LHCb experiment at CERN’s Large Hadron Collider announced the discovery of two new particles in the baryon family. The particles, known as the Xi_b'- and Xi_b*-, were predicted to exist by the quark model but had never been seen before. A related particle, the Xi_b*0, was found by the CMS experiment at CERN in 2012. The LHCb collaboration submitted a paper reporting the finding to Physical Review Letters.
Evolution is a funny thing. All organic creatures evolve in response to changes in their environment. And then in turn, the environment changes in response to new behaviors from the organisms that inhabit it.
Officials with Google have revealed that researchers working on a start-up recently purchased by the tech giant are working on building what they call a Neural Turing Machine—an artificial intelligence based computer system that seeks to fulfill the idea of a Turing Machine. Teams with the project ...
These days, you can hardly have a technology conversation without talking about the Internet of Things (IoT). And when that conversation shifts its focus to the industrial sector, including energy, Oil & Gas, Power & Utilities, and petrochemicals, among others, the discussion changes to what is being called the “Industrial Internet of Things” (IIoT). So…
When electrons or atoms or individuals or societies interact with one another or their environment, the collective behavior of the whole is different from that of its parts. We call this resulting behavior emergent. Emergence thus refers to collective phenomena or behaviors in complex adaptive systems that are not present in their individual parts.

If modern physics is to be believed, we shouldn’t be here. The meager dose of energy infusing empty space, which at higher levels would rip the cosmos apart, is a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion times tinier than theory predicts. And the minuscule mass of the Higgs boson, whose relative…
Microsoft co-founder Paul Allen has been pondering artificial intelligence since he was a kid. In the late '60s, eerily intelligent computers were everywhere, whether it was 2001's HAL or Star Trek'...
