  • Welcome to a world of teleportation!

  • Where you can wake up in a remote corner of the world,

  • teleport to work in Tokyo,

  • and end your day by catching the opera in Rome!

  • This idea of beaming yourself from one location to another

  • used to be just the stuff of science fiction,

  • but now scientists are starting to uncover the technologies that can make it a reality.

  • This is WHAT IF, and here's what would happen if teleportation was possible.

  • The most likely way that humans will start teleporting

  • will be through something called quantum teleportation.

  • Quantum teleportation involves scanning an object

  • and transmitting its information to another location,

  • where that information is used to reassemble the object from different molecules and atoms.

  • The prospect of human teleportation

  • could lead to a pretty different looking life for you and me.

  • Our bridges and roads could become desolate wastelands,

  • dense cities might become a thing of the past,

  • and space exploration might accelerate at a pace that we're not ready for.

  • But before we get too far ahead of ourselves, let's look at how this would actually work.

  • It all starts with a little thing called quantum entanglement.

  • Quantum entanglement involves linking particles together,

  • and keeping them connected, even across vast distances.

  • When particles are "entangled,"

  • it means that they're forced to hold mutually exclusive states;

  • so if we know the state of one, then we'll know the state of the other.

  • Think of it like this,

  • if you ordered a beef burger and a chicken burger from a fast food place,

  • you wouldn't be able to tell which one is which without opening the boxes.

  • But once you open one box, you automatically know what's in the other one,

  • and that knowledge doesn't change, no matter how far away the other box is.

  • Yeah, it's complicated, but the main takeaway for us

  • is that once two or more particles are entangled,

  • we can teleport information between them.

  • Researchers in China have already proven this to work

  • by transferring properties of a particle to a satellite in space,

  • but how does that translate to teleporting human beings?

  • Well, every human body is made up of billions upon billions of atoms;

  • and each atom is a set of data

  • describing the type of atom, location, energy state, and so on.

  • So theoretically we should be able to scan the atomic information of a human body,

  • teleport it to a far-off location, and re-build the body just the way it was.

  • But of course, it can't be that simple!

  • To find out the physical state of every atom that makes you 'you,'

  • you'd have to disintegrate your entire body.

  • That means that everytime you'd teleport, you'd essentially be committing suicide,

  • and getting reborn on the other end.

  • Quantum entanglement is a finicky process, to say the least,

  • and no one has ever transmitted this much information,

  • so at this point, human teleportation would most likely be a pure suicide mission.

  • But the fundamental technology is there, and will only continue to develop,

  • so don't give up hope yet.

  • Maybe some day soon we'll be able to teleport across the world in seconds,

  • and international borders would disappear because they could no longer be enforced,

  • but that's a topic for another WHAT IF.
