Teleportation

Human Teleportation

The man is standing on a platform called transporter and he is beamed up part by part and teleported accordingly. The human body consist of 1028 atoms. So we have to teleport these atoms with exact precision. A duplicate of the person would be made at the other end. Original mind and body no longer exists, their atomic structure would be recreated at the other end. But there are some limitations.

Quantum Teleportation

Scientists found a way to scan out part of the information from an object A, which one wishes to teleport, while causing the remaining, unscanned, part of the information to pass, via the Einstein-Podolsky-Rosen effect, into another object C which has never been in contact with A. Later, by applying to C a treatment depending on the scanned-out information, it is possible to maneuver C into exactly the same state as A was in before it was scanned. A itself is no longer in that state, having been thoroughly disrupted by the scanning, so what has been achieved is teleportation.

Abstract

Teleportation is the name given by science fiction writers to the feat of making an object or a person disintegrate in one place while a perfect replica appears some where else. A teleportation machine would be like fax machine except that it would work on three dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. Teleportation was not taken seriously by scientists, because it was thought to violate the uncertainty principle of quantum mechanics, which forbids any measuring or scanning process from extracting all the information in an atom or other object.

Mechanism Of Quantum Teleportation

Before going into more detail about the teleportation experiments performed to date, let us firstly get a better idea about what teleportation actually is. To begin with, a key part of this process involves something getting from one place to another without it moving through any places in between. For example, imagine that you can teleport from school to home. This means that you are able to get home without having to walk, catch a bus or a train, ride your bike or indeed use any other type of everyday transport. Instead, you are simply "beamed" there.

Quantum Computers

The basic data unit in a conventional (or classical) computer is the bit, or binary digit.. A bit stores a numerical value of either 0 or 1. An example of how bits are stored is given by a CD rom: "pits" and "lands" (absence of a pit) are used to store the binary data. In quantum computing, the byte is replaced by a single talks to you about the 'Mona Lisa', by just hearing the name, you know what the picture looks like without having been given the enormous string of Is and Os that the element called a qubit. A qubit is in effect a single entity rather like a conventional computer's bit, but actually it is a combination of many quantum states of atomic or sub atomic particles. In a single qubit it is possible to carry lot of zeros and ones all together but in a single quantum bit imagine a picture of MonaLisa is stored in the computer as millions of bits. However, if somebody computer needs to redraw it. In the same way, in a quantum computer, the qubit is the equivalent of the name 'MonaLisa'.

Introduction

Teleportation involves dematerializing an object at one point, and sending the details of that object's precise atomic configuration to another location, where it will be reconstructed. What this means is that time and space could be eliminated from travel - we could be transported to any location instantly, without actually crossing a physical distance.

Conclusion

The future of teleportation is as varied as the past that led to its creation. Society's fascination with teleportation gives the drive for further research strong ensuring teleportation as an integral part of society's progress. Science, however, can only go as far as society will allow, making ethical dilemmas a key issue in the potential uses of teleportation.
