A radical new theory by a well-respected scientist suggests that consciousness is a state of matter, like a liquid or gas. According to MIT's Max Tegmark, "perceptronium" gives rise to various types of consciousness when certain mathematical and physical conditions are met. » 4/23/14 3:20pm Yesterday 3:20pm

Physicists say energy can be teleported 'without a limit of distance'

A team of physicists has proposed a way of teleporting energy over long distances. The technique, which is purely theoretical at this point, takes advantage of the strange quantum phenomenon of entanglement where two particles share the same existence. » 1/29/14 1:30pm 1/29/14 1:30pm

Student Rickrolls his teacher in this ingenious quantum physics essay

We've seen creative Rickrolls before, but this one takes the cake. Physics student Sairam Gudiseva Rickrolled his teacher by surreptitiously inserting every word of Rick Astley's "Never Gonna Give You Up" into — of all things — a quantum physics essay that still makes perfect sense. » 1/17/14 6:40am 1/17/14 6:40am

New evidence that plants get their energy using quantum entanglement

Biophysicists theorize that plants tap into the eerie world of quantum entanglement during photosynthesis. But the evidence to date has been purely circumstantial. Now, scientists have discovered a feature of plants that cannot be explained by classical physics alone — but which quantum mechanics answers quite nicely. » 1/10/14 4:00pm 1/10/14 4:00pm

​What will NASA be doing with its new quantum computer?

Earlier this year, NASA, in partnership with Google, acquired the world's largest quantum computer. But just what does the space agency plan to do with a device with such revolutionary potential? We talked to one of their lead researchers to find out. » 11/20/13 11:40am 11/20/13 11:40am

Quantum Computing Takes a Gigantic Leap Forward

An international team of scientists have just held a qubit's memory state for 39 minutes. That might not sound like much, but it's 100 times longer than the previous record. It's a groundbreaking achievement that could pave the way to freakishly fast computers. » 11/15/13 1:00pm 11/15/13 1:00pm

Scientists teleport information in an electronic circuit

We’re still a far way’s off from being able to beam people through space, but in a science first, physicists have successfully transported information across a solid state system similar to a computer chip. The breakthrough could lead to more powerful processors and highly sophisticated encryption schemes. » 8/15/13 11:30am 8/15/13 11:30am

If this theory is correct, we may live in a web of alternate timelines

The Many Worlds Interpretation of quantum physics has been around for nearly 60 years. It’s a highly controversial idea which suggests that our world — and everything in it — is constantly splitting into alternative timelines. If it's correct, here's what your true existence might actually be like. » 7/24/13 10:34am 7/24/13 10:34am

The Webcomic Guide to Quantum Physics

Last year, Jorge Cham of the webcomic Piled Higher and Deeper (a.k.a. PhD comics) combined animation with expert interviews to explain the Higgs Boson and black body radiation. Now, he's trying his hand at quantum physics – a subject, he admits, he is somewhat mystified by. » 6/12/13 7:10am 6/12/13 7:10am

Did government scientists really create a secret quantum internet?

No, not really. But for two years, researchers at Los Alamos National Labs have been working on something they call network-centric quantum communications — and this could usher in the next generation of hyper-secure, scalable, and affordable quantum cryptographic techniques. We spoke to the lead researcher to find out … » 5/10/13 11:00am 5/10/13 11:00am

Why quantum mechanics is the biggest embarrassment in all of modern…

It's been close to a century since we established how quantum mechanics "works," and we still don't know what it really means — and that, says cosmologist Sean Carroll in the video up top, may make QM the most embarrassing subject in all of modern physics. » 2/07/13 8:40am 2/07/13 8:40am

Is light a particle, a wave, or a bunch of tiny, photon-gathering…

Check out the wave-particle duality as presented by Colm Kelleher and animated by Nelson Diaz for TEDEd; it's a clever explanation to a longtime quantum conundrum. Even better: it's delivered with a lilting Irish accent — which makes the historical bit about the eye-horses that much more entertaining. » 1/21/13 6:40am 1/21/13 6:40am

Poll shows that quantum physicists agree to disagree about the nature…

Quantum mechanics is real. It's spooky as hell, but it's real. Without its microscopically small probabilistic effects, we wouldn't have superconductors, lasers, and many forms of computing and cryptography. But despite our laboratory certainty, what's less clear is the role it plays in the fundamental nature of… » 1/14/13 3:30pm 1/14/13 3:30pm
