An experiment that might let us control events millions of years ago

Most of us have heard of the famous double-slit experiment. Usually it's played out in a lab in seconds. But there's one version, dreamt up by physicist John Archibald Wheeler, that can be played out over much of the galaxy, over millions of years. His thought experiment suggests that we could retroactively determine… » 2/19/14 12:04pm 2/19/14 12:04pm

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

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

Why can't Einstein and Quantum Mechanics get along?

Despite our successes at describing the inner workings of the universe (Higgs, anyone?), there are still some gaping holes in our knowledge. Where's our Grand Unified Theory or our Theory of Everything? And why is Einstein's General Relativity still at odds with Quantum Mechanics? Why should we want to unify them… » 8/09/13 12:24pm 8/09/13 12:24pm

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

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

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

Quantum Suicide: How to Prove the Multiverse Exists, in the Most…

Quantum mechanics says objective reality doesn't exist, that instead all we see are probabilities collapsing into one particular configuration... and all other possible realities might just exist together in a quantum multiverse. Here's the deadly experiment that could help you to test that very idea. » 3/08/12 3:07pm 3/08/12 3:07pm
