A new research paper brings new meaning to the joke that all science is just physics. A team of scientists at the National University of Singapore suggests that it is quantum entanglement that holds our DNA together.
It's hard to prove, but it would be a potentially explosive finding, as Technology Review explains.
Scientists in China have broken the record for quantum teleportation, achieving a distance of about 10 miles, according to a new study in Nature Photonics. That's a giant leap from previous achievements.
The feat brings us closer to communicating information without needing a traditional signal transmission, the researchers note.
How many cats have to be both dead and alive before researchers are content that they've entangled enough particles? The current count is now five, but research published today in the Science suggests that it could be many more than that. Perhaps that's bad news for Schrodinger's cat, but it's great news for quantum pursuits like precision imaging and ultra-fast computing.
Scientists have long speculated that birds navigate the globe using magnetism; however, a new study suggests that quantum entanglement indeed enables birds to "see" the Earth's magnetic field as if it were a pattern of colors.
When we think of quantum mechanics, we often think of the very small and the very theoretical. Take Schrodinger's Cat for instance; it's an interesting thought exercise but not an experiment one would want to actually execute in his or her apartment. But a researcher at UC Santa Barbara has brought quantum systems down from the chalkboard and into plain sight, creating the first mechanical device large enough to be observed with the naked eye that behaves as a true quantum system, bridging the divide between the macro world of mechanical systems and the micro domain of quantum physics.
How fast is too fast? According to the laws of physics, the speed of light is a good boundary, as going beyond it opens you up to all sorts of paradoxes and space-time phenomena that are usually the stuff of sci-fi. But a couple of researchers in Austria have come up with a way to compute information faster than the speed of light.
In a paper published last week, MIT physicist Lorenzo Maccone hypothesizes that, yes, quantum physics is messing with our minds. The laws of physics work just as well if time is running forwards or backwards. But we all seem to experience time running in only one direction, and in the same direction as everyone else -- a mystery of physics that's yet to be solved.
