Beam Me Up Scotty? A Q&A about Quantum Teleportation with H. Jeff Kimble

Why the effect is nothing like Star Trek















Share on Tumblr

Do you watch Heroes on NBC?
No. I watch some of the football playoffs.

But you know Captain Kirk…

I have some advice. Just don't talk about teleporting people in your story. The technical base of our society is information commerce, and in the next 20 years it will radically change. Read the semiconductor industry's roadmap. We're just going to gleefully think it's going to happen on the movie screen, and we will ignore investments in science and technology.

There's a really incredibly exciting frontier in science that didn't exist 15 or 20 years ago, and it's this quantum information science, which brings together traditional computer science and quantum mechanics. There's stuff going on that is just titillating.

    This should not be called teleportation ... I could just as easily fax the electron spin information and get the same result.

    @axualalien
    no. you could not. you cannot measure properties of the electron to fax them because as soon as you do, they are not what you measured. Thats why the intermediary particle is required and why it relies on entanglement.

    In Star Trek they used a Heisenberg compensator.

    "the base of our society is information commerce"

    thats a very short explanation on how such a thing will be incredibly useful and utilized in all kinds of fields during the next ten years.

    the very face of commerce itself (as we know it) is about to change substantially.

    It's a good thing that physical teleportation isn't what we are talking about. Teleportation of the physical object moving variety is the ultimate superweapon that would remake world politics in a matter of days and change warfare forever. Those who got this capability would have a strike anywhere instantly capability with no trail indicating who did it. For instance, on a small scale teleporting a little piece of a heart into a location 2 centimeters away would kill. On a large scale, teleporting a city to the far side of the moon for 30 minutes and then right back where it was to begin with would kill everyone.


    So it's a good tihing that's not what this "teleportation" business is talking about.

    Pythagoras, Euclid also, concluded that zero time occurs between any two or more points on the real line which is still the fundamental mathematical system for analysis of teleportation of objects in the vector universe. I think we may have two or three schools of science thought: vector holographic systems, digital pixel systems and quantum based energy systems. Since magnetism lacks a door to human life, i.e. Philadelphia invisibility experiments, the vector hologram system will probably win out in the future. Why? because the time between any two points on the line (in the universe) is 1-millionth second on two sides: into the tunnel and out of the tunnel. Thus, nobody would die or freeze to death or need to be taken apart to traverse any distance. BRB.

    Science Fiction has a way to predict what will NOT happen in the comming years, Quantum teleportation is the key to secure communications, data storage (as in the "frozen photon" experiments), and probably supraluminic comunication (if you could somehow make an entangled particle "dance" like a cartesian diver), but you won't be seeing a disappearing act a la Kirk because the particles you use must be entangled first, that would mean you have to send an equal mass to your average Redshirt down to the planet before sending him, and then what is the purposse of such a maneuver? you still need a shuttle to haul down an even more fragile mass than your redshirt.

    Never say never.
    A few years before the Wright's brothers first flight
    the top British Scientist of the day declared that manned flight is impossible.
    An other one said around the same time"everything that can be invented has been invented".

    I really dont understand the difference between teleporting the quantum state vs. sending a signal by transmission. I see the original entanglement will still be at point A and perhaps electron 532 state will be transported but what exactly does that mean? The information will get there anyway right?

    how true!
    this is Not teleportation, it is replication.

    What if entaglement is nothing more than the flow of space-time between two particles no matter how small they are,and space-time is so called dark energy?An excample would be eletromagnitism where S-pole is outward flow,and N-pole is inward flow,thus you couldn't have a monepole,because it's just a matter of direction of flow.
