The 9 Weirdest Implications Of The Many Worlds Interpretation

According to the Many Worlds Interpretation of quantum physics, we live in an infinite web of alternate timelines. It's a serious claim that carries some rather serious scientific, philosophical, and existential baggage. And here are the nine weirdest possible implications. » 3/23/15 10:00am 3/23/15 10:00am

New 'Quantum Bounce' Theory Explains How Black Holes Become White

Some cosmologists speculate that black holes end their lives by transforming into their exact opposite — so-called 'white holes' that pour all the material they gobbled up back into space. A new theory based on quantum gravity could explain how this is possible. » 7/21/14 10:30am 7/21/14 10:30am

Are Quantum Computers Just as Slow as Conventional Ones?

A new study claims that the D-Wave quantum computer is no faster than the PC on your desk, leading many to proclaim the technology as overhyped. Trouble is, the performance tests were too easy and not a true measure of what these machines are capable of doing. » 6/20/14 4:00pm 6/20/14 4:00pm

This Algae Can Switch Its Internal Quantum Computer On And Off

Scientists have shown that certain algae which use quantum effects to optimize photosynthesis are also capable of switching it off. It's a discovery that could lead to highly efficient organic solar cells and quantum-based electronics. » 6/18/14 1:30pm 6/18/14 1:30pm

Scientists have teleported quantum information between two bits of diamond located 10 feet apart. It's a prime example of "spooky action at a distance" — and an achievement that could lead to quantum networks exponentially more powerful and secure than today's supercomputers. » 6/02/14 3:20pm 6/02/14 3:20pm

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 4/23/14 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

An apparent discovery of quantum vibrations in microtubules inside neurons is rekindling a 20-year old debate on the nature of consciousness. Called the Orch OR model, it suggests there's a connection between the brainʼs biomolecular processes and the basic structure of the universe. » 1/21/14 3:20pm 1/21/14 3:20pm

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

New research on wormholes suggests that these theoretical shortcuts that connect distant points in the universe might be linked with the spooky phenomenon of quantum entanglement. As Charles Q. Choi writes in LiveScience, this would allow particles to be connected regardless of how far apart they are — a finding that… » 12/04/13 12:40pm 12/04/13 12:40pm

​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

Teleportation just got easier – but not for you, unfortunately


Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? » 8/23/13 2:51pm 8/23/13 2:51pm

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

This Is a Heat Map of a Single, Living Cell

By using a microscopic diamond and some gold nanoparticles, researchers at Harvard have measured the internal temperature of a living human embryonic cell. This groundbreaking new ‘nanothermometer’ could lead to therapies in which specific cells are treated. » 8/02/13 1:27pm 8/02/13 1:27pm

Does infinity really exist?

Our universe appears to be bound by a finite set of laws, yet we often talk about things that go on for an eternity. "Infinity" is a strange idea. But it's crucial if you want to understand anything from philosophy to mathematics. Here’s why. » 7/31/13 10:42am 7/31/13 10:42am

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
