Looks like today's the day to head out to the garage and build yourself a perpetual motion machine, since Japanese physicists have just shown how to smash the classical second law of thermodynamics to smithereens using quantum entanglement.
Quantum cryptography may be theoretically secure, but in practice, there are certain limitations that allow clever attackers to read encrypted messages. A new system that ditches quantum mechanics for classical mechanics may prove to be even more secure, backed up by the Second Law of Thermodynamics.
It doesn't get much more futuristic than "universal quantum network," but we're going to have to find something else to pine over, since a UQN now exists. A group from the Max Planck Institute of Quantum Optics has tied the quantum states of two atoms together using photons, creating the first network of qubits.
Throw away that dusty Magic 8-Ball. All your key decisions can now be made with a new toy operating on the theory behind an experiment in quantum mechanics. I should point out before we continue there is no real dead cat involved with the toy, just the theory behind it. It's fun! I promise.
Creating light is something that's usually done with a light switch, right? But what if you didn't have a light switch? A team of Swedish physicists were presented with such a conundrum, so they've gone and convinced a bunch of photons to spontaneously create themselves out of nothingness.
My fantasy. Your fantasy. Marty McFly's 2015 reality from Back to the Future Part II. The hoverboard now exists, for real, thanks to the magic of superconducting magnets, quantum levitation, and the boundless brilliance and ingenuity of the French.
Have you watched the news lately? It's all war, calamity, and recession out there. Yes, things are rather bleak at this particular point in history. If only there was some way we could travel back to the past so as to avoid all these messes — or failing that, just cut our losses and jump forward to a future time when our descendents will have fixed everything with all their space ray guns and future doohickey whatnots. If only. Well, as it turns out, lots of people are actively working towards the dream of expanding the one-way street of time into a multi-lane superhighway! Of course, many of these time pioneers are completely whackadoodle. But within the temporal engineering profession, you can also find accomplished researchers pursuing serious, science-based approaches to time travel. Yesterday, we looked at various time travel theories inspired by science fiction. Here, we highlight three of these proposed methods of temporal manipulation that aren't only attracting serious consideration, but might be available sooner than you think.
Those greedy scientists, they just can't learn to share. Instead of going out and getting two little glass spheres, they're trying to use a trick of quantum mechanics to take one little glass sphere and make it exist in two places at the same time.
As it turns out, the universe is totally out of its mind. Not that we don't love the universe with all its bizarre eccentricities and flagrant violations of its own physical laws — we do! There's lots of cool stuff out there. However, we simply can't ignore the fact that the science describing the gritty true nature of all things inevitably leads to one conclusion: the cosmos is completely crazy pants. To help sort through the giant logic purée that is our universe, we have picked out five of the most counter-intuitive, hair-melting scientific ideas for closer inspection. Come join us as we try our best to machete through the dense jungle of formulas and brain-sizzling conclusions and clear the path to comprehension. Or something approaching it. Wish your brain "good luck and safe travels." It's going to need it.
What would you do with 128 programmable quantum bits? If you're not certain, perfect, that's just what it's designed for. Just for heaven's sake don't look at it or it'll stop working. Welcome to the wonderful world of quantum mechanics.
