Physicists Cracked The Mystery Of Teleportation
Teleportation or teletransportation is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction literature, film, video games, and television. Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains how teleportation can be done. Following is a transcript of the video.
Brian Greene: I’m Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival. Teleportation is one of the weird ideas, and there is a version of it that physicists now routinely make use of. Nobody is teleporting people from place to place.
But we can teleport individual particles. We can take a particle at one location, and then in some sense create an absolute identical version of it, exactly the same properties, exactly the same quantum state, if you let me be a little technical.
And that means, in essence, you’ve gone from a particle that was here to one over here. And in fact, the process itself destroys the particle over here. So, the only version of this particle that exists when this process is over is the one that’s been created at this location.
And people do this. There is a very very smart physicist — Anton Zeilinger. He routinely teleports particles from Tenerife to La Palma. It’s an amazing thing that you can actually do this. The big question, of course, is: Will you ever teleport big things like people?
