“The person left over would be a blank canvas,” Shalm explains. Left behind in Japan would be only a pile of atoms without the corresponding information about where everything goes. This method would move all the details about the person from Japan to a waiting pile of atoms in Brazil. So you don’t end up with a copy of a person in Brazil and an unfortunate clone left behind in Japan. The advantage of this kind of transfer, Shalm says, is that the data are teleported, not copied. If the scientist in Japan has data on a third electron (electron C) to send to Brazil, then, Gorshkov explains, they can use A to send a bit of information about C to the entangled particle B in Brazil. That’s true even though she’s never seen that faraway electron. If electron A in Japan is entangled with electron B in Brazil, a scientist measuring the speed of A also knows what B’s speed is. When two electrons are entangled, something about them - their position, for example, or which way they spin - is perfectly connected. This is when particles - say, negatively charged particles called electrons - are linked, even when they aren’t physically close to each other. Teleportation in the quantum world requires something called entanglement. (In the Harry Potter universe, he says, he’d be a Slytherin.) He’s a physicist at the National Institute of Standards and Technology in Boulder, Colo. “But we do have something kind of similar, and we call it quantum teleportation,” says Krister Shalm. In quantum physics, apparition still isn’t possible. Quantum physics is used to explain how matter behaves at the very tiniest scale - single atoms and light particles, for example.Įxplainer: Quantum is the world of the super small Could they really? Let’s get quantumĪnother way of moving data from one place to another comes from the quantum world. In the world of Harry Potter and Newt Scamander, wizards can appear and disappear in swirls of magic. Still, you’d be alive in Brazil, as a copy of yourself - at least in theory.

But, he notes, the process of getting all that information about the position of every atom in your body might kill you anyway. “The original copy would still be there, and someone would probably have to kill you there,” Gorshkov says. But the bigger problem is that you end up with two copies of the same person. For one, scientists don’t have any way to figure out the position of every single atom in the body. There are some problems with this method of apparition. When the data arrive, you could take a pile of matching atoms - carbon, hydrogen and everything else in a body - and assemble a copy of the person in Brazil. Then, you would put all those data into a very advanced computer and send them somewhere else - say from Japan to Brazil.

“It’s a full description of a human being, all your flaws, and where all your atoms are,” Gorshkov explains. First, you would have to learn every itsy bitsy thing about a person. In a world without magic, though, how could someone move that fast? Gorshkov has an idea. And that delay would be bigger the farther they traveled. There would just be a very slight delay between when they’d disappear and appear. So if someone were to apparate at light speed, they’d move pretty quickly. At speeds like that, you could get from London to Paris in 0.001 second. Light speed is about 300 million meters per second (some 671 million miles per hour). (In the Harry Potter world, he notes, he’d be a Gryffindor.) “Even teleportation is limited by the speed of light,” he says. He’s a physicist at the Joint Quantum Institute in College Park, Md. “Nothing can really be transported from one place to another faster than the speed of light,” says Alexey Gorshkov. Such instantaneous travel would be blocked by a universal limit, the speed of light. That’s one reason why nobody is ever going to apparate instantly from one place to another.

The only catch? The process would probably kill you.Ĭharacters in movies and books - like the magic users in the Harry Potter series by J.K. Put enough of those atoms together, and it might actually be possible to create a copy of yourself somewhere else. But while it is impossible for anyone to apparate from home to school or work, an atom is another matter. No one in the real world has this talent, especially not poor Muggles (non-magical people) like us.

In the universe where Harry Potter, Newt Scamander and fantastic beasts can be found, witches and wizards abound - and they can teleport from one place to the next.
