Teleportation a reality or Sci-fi?

Question

Has anyone ever wonder if teleportation could come to a reality one day?

Does anyone have any clue how it can be done if possible or the physics behind? Or will this be defying the laws of relativity?

Answer 1

anything is possible.

Answer 2

You are correct that instantaneous teleportation would defy relativity. What others are referring to when they say electrons teleport is not the same as the conventional idea of teleportation.

The "teleportation" of particles has to do with the fact that there is always a degree of uncertainty in the location of a particle. It is important to know however that this is not experimental uncertainty. The electron does not have an exact location, until something interacts with it (such as another particle colliding with it or a photon bouncing off of it).

Anyways, this nature allows electrons to jump from place to place in a sense, but not in the conventional "teleportation" way.

You may ask well why can a electron "jump" but I can't? Well the answer to that is that the probability to make the jump is inversely proportional to the mass of the object in question. Well, even specks of dust (let alone people) are incomprehensibly more massive than electrons, which translates into an incomprehensibly small probability of any macroscopic objects of "teleporting" in the same way an electron does.

Answer 3

With present techniques, "exact" (quantum) teleportation is possible only with photons and atoms.[1] "Inexact" teleportation (where quantum states are not preserved), is possible by encoding information about an object, transmitting the information to another place, such as by radio or an electric signal, and creating a copy of the original object in the new location. Teleportation has also been proposed to explain various anomalous phenomena, and the concept has been widely used in science fiction.

Similar is apport, an earlier word used to describe what today might be called teleportation; and bilocation, when someone is said to occupy two places simultaneously. The word "teletransportation" (which simply expands Fort's abbreviated term) was first employed by Derek Parfit as part of a thought exercise on identity.

Answer 4

Several groups are playing with so-called cloaking device for personnel and vehicles. However, in order to make it a feasible device, it will involve the use of nanotechnology which is still in its infantile stages. Experts estimate they may have something to work with 10-20 years down the road. Teleportation will have to remain in the sci-fi and theoretical stages for now; at least with the technology currently available to us. Consider that teleportation involves breaking down an original, and in the case of living beings, an original in constant motion. In order to make this feasible, you would have to find a way to take the original apart at the atomic level, transport the trillions of atoms, several of them in constant motion(meaning you'd have to hit millions of moving targets) to another location, and accurately place every atom in the precise location it was at before teleporting. Even if one could find a way to teleport at this level, how could they ensure the safety of the one being transported? How do you sustain life during transport? What happens if a couple atoms are out of place at the end? The results could be catastrophic. Mind reading computers? For the time being I'd have to say not going to happen. But since they do have machines that read brain waves and such, so I'm not going to totally discount this one. However, it won't happen anytime soon.; and its accuracy will definitely be in question. So much is still unknown about the brain.

Answer 5

It is REALITY today. They can teleport small objects and small things. They are working on transporting larger objects. UPS is the laboratory's first client. It is all quantumn physics based stuff. They can also teleport light and laser beams as well. It may be a few more years before the technology is developed enough for true commercial use.

Quite frankly, the ONLY thing we DONT have from Star Trek is the Warp Drive at this point..

Answer 6

i was reading about i think 10 years ago that scientests in europe designed a machine that could teleport a small box the size of a ring box not far about a foot i believe and said it took a incredible amount of memory to do. and as for a human the article didn't think we would be able to store the amount of information needed to transport a human in this lifetime.

Answer 7

The use of teleportation as a means of transport for humans still has considerable unresolved technical and philosophical issues, such as exactly how to record the human body sufficiently accurately and also be able to reconstruct it, and whether destroying a human in one place and recreating a copy elsewhere would provide a sufficient experience of continuity of existence. Believers in the supernatural might wonder if the soul is recopied or destroyed, and might even consider it murder. Likewise, someone with a secular worldview who considers the body synonymous with the self might also see the disintegration of a given corpus as the killing of a human being. The reassembled human would be a different sentience with the same memories as the original. Many of the questions are shared with the concept of mind transfer.

It is not clear if duplicating a human would require reproduction of the exact quantum state, requiring quantum teleportation which necessarily destroys the original, or whether macroscopic measurements would suffice. In the non-destructive version, hypothetically a new copy of the individual is created with each teleportation, with only the copy subjectively experiencing the teleportation. Technology of this type would have many other applications, such as virtual medicine (manipulating the stored data to create a copy better than the original), traveling into the future (creating a copy many years after the information was stored), or backup copies (creating a copy from recently stored information if the original was involved in a mishap.)

Another form of teleportation common in science fiction (and seen in The Culture and The Terminator series of films) sends the subject through a wormhole or similar phenomenon, allowing transit faster than light while avoiding the problems posed by the uncertainty principle and potential signal interference. In both of the examples above, this form of teleportation is known as Displacement or Topological shortcut (Scientific American). (In the Terminator movies, Skynet used its displacement technology to produce a time machine, and thus named it the "Time-Space Displacement Equipment.")

Displacement teleporters eliminate many probable objections to teleportation on religious or philosophical grounds, as they preserve the original subject intact — and thus continuity of existence.

p-Teleportation means of teleportation are sometimes referred to as "psychoportation", or "jaunting"; named after the fictional scientist (Jaunte) who discovered it in The Stars My Destination (originally titled Tiger! Tiger!), a science fiction novel by Alfred Bester.

In religious, occult, and esoteric literature, teleportation is the instantaneous movement of a person or object from one place to another, by miraculous, supernatural or psychic means rather than technological ones. For instance, in Acts 8:39, after Philip evangelized an Ethiopian official: "When they came up out of the water, the Spirit of the Lord suddenly took Philip away, and the eunuch did not see him again, but went on his way rejoicing."

Teleportation lab experiments

In June 2002 the Ph.D. project of Dr. Warwick Bowen led by Dr. Ping Koy Lam, Prof. Hans Bachor and Dr. Timothy Ralph of the Australian National University achieved (quantum) teleportation of a laser beam.

It was a successful quantum teleportation experiment involving the use of 'entangled' photons. A target photon was successfully 'scanned', its properties 'copied' onto a transition photon, and finally the photon was recreated at another location of arbitrary distance, proving in essence the theorems proposed by Einstein to explain his 'strange action at a distance'.

Scientists teleported atoms in 2004.

October 2006 - For the first time, Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark have conducted a teleportation experiment involving a microscopic atomic object containing thousands of billions of atoms. They teleported the information a distance of half a metre. "For the first time, it involves teleportation between light and matter, two different objects"

Answer 8

Actually they have already succeeded in teleportation, of electrons that is.I believe they teleported one electron about a centimeter or something, but they are working on it. We'll see if it ever becomes practical.

Answer 9

i would say if we can get to the point where the atom is split then we can manipulate enough atoms in some sort of light ray enabling teleportation.

Answer 10

i read somewhere that scientists think they managed it

Don't get excited though they done it with one atom only, or was it one electron. it was something very small anyway.

it might be possibly one day , but the processing power of the pc would need to be massive

Answer 11

It's sci-fi today.
