Quantum computers could immeasurably speed up the rate at which calculations run—but so far, their promise has yet to be realized. Now, a team of researchers has built a versatile quantum chip that it reckons could be pieced together to create a powerful computational device.
For decades, Schrödinger’s famous thought experiment involving a cat has been the turn-to illustration of quantum mechanics. But now there’s a new quantum puzzle, which asks: Can three pigeons be placed into two pigeonholes with no two pigeons being in the same hole?
Once you’ve put a satellite into space, that’s normally kind if it. There’s not usually a lot of replanning once your technology is in orbit, meaning that if you want to change something like the broadcast frequency, you’re stuck. That’s the reason these transforming satellites exist.
The lure of quantum entangled computing is strong, as it can provide a means of impenetrable encryption—but the hardware has always been too bulky to make it practical. Now, though, researchers have shrunk the technology down to less than the width of a human hair, small enough to squeeze onto a chip.
While quantum mechanics is tough to get your head round, you probably know about Schrödinger’s poor old cat: left in a box, both alive and dead at the same time. Well, now there’s a picture of the ill-fated feline.
Although it sounds entirely like something dreamed up in a smoke-filled dorm room, whether the entire universe is hologram is a very serious question—a question that gets at the heart of a fundamental problem in physics. A new experiment starting up at Fermilab just might hold the answer.
People that know about quantum mechanics tend to talk about it very breezily, leaving us mortals behind. Be left behind no longer, though, with this wonderful little video.
We take GPS so much for granted on land that it's easy to forget where GPS doesn't work—like deep underwater, where only strange sea creatures and submarines roam. Enter the bizarre new world of quantum positioning, where supercooled atoms could be the future of navigation.
Random numbers fuel our digital lives, but they're notoriously difficult to generate properly. Now, scientists have shown that smartphone cameras can be used as quantum random number generators—and it could change the face of mobile security.
It might look understated, but you're looking at the most functionally complex integrated quantum circuit ever made from a single material—and it can both generate photons and entangle them, all at the same time.
With Minute Physics videos we pretty much expect to have the universe explained to us in . . . a minute. Or maybe a few minutes. But this rundown of temperature and how to achieve "negative temperature" only takes 10 seconds. Impressive.
Every so often, the thing you've been looking for all along is right under your nose. Like the latest material to offer itself up as the future of quantum computing—which has been sitting on banknotes for decades.
You've heard plenty of people by now—including us—banging on about quantum computers, and how they’re the future of high-performance computing. Quantum computing, we're meant to understand, is set to change the world. But despite its promise, it's neither widely available nor particularly useful yet. Here's why not.
You've probably heard people—including us—banging on about quantum computers for a long ol' time. But that doesn't necessarily mean you know exactly how they work. Fortunately this video is here to help.
Behold, the beating heart of a time machine! Or "clock", as most people call them, but this one is nothing like your grandfather's. This super-accurate timekeeper is an optical atomic clock built by the UK's National Physical Laboratory (NPL) and its tick is governed by a single ion of the element strontium.
While Sony might currently be spoken about in TV circles for its blazing 4K sets, the future could hold something quite different. In fact, Sony's Next Big Thing—Triluminous displays—will be powered by quantum physics.
While people get excited about future internets being powered by quantum particles, nobody really knows how that's going to work yet. But Chinese physicists have taken a step in the right direction, by creating the world's first quantum router.
Like quantum physics? What about quantum computers? Or quantum computers in a diamond? Then you should know that researchers at the Max Planck Institute have appropriately devised a way to create a quantum network in which a photon is exchanged between two atoms. Future!
Today's quantum computers are no more than experiments. Researchers can string together a handful of quantum bits - seemingly magical bits that store a "1″ and "0″ at the same time - and these ephemeral creations can run relatively simple algorithms. But new research from IBM indicates that far more complex quantum…
