Teleportation is the transmission of a life-size image of a person to appear within a room at a distant location where the person has a telepresence for engaging in natural face to face communication with people at the distant location. The image of the person appears within a 3D environment, can make eye to eye contact with individuals and can hold true two-way conversations. This is a unique system invented by a privately held Richardson based firm by the name Teleportec Inc. They are mainly operating in USA and UK.

Teleportation systems are better than videoconferencing. Videoconferencing has never presented itself as a realistic alternative to face-to-face meetings because of its severe limitations - only one person can speak at any one time creating an amplified feeling of distance between participants. With videoconferencing people feel uncomfortable by being on camera and feel disconnected from the people shown on the screen. Teleprtation gives a sense of presence by achieving eye-to-eye contact with a distant person who is teleported into the room

INTRODUCTION:-
• Ever since the wheel was invented more than 5,000 years ago, people have been inventing new ways to travel faster from one point to another.
• To avoid the problem of covering a physical distance and to minimise the time ,there are scientists working right now on such a method of travel, combining properties of telecommunications and transportation to achieve a system called teleportation
TELEPORTATION:-
• Teleportation involves dematerializing an bject 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.
• In 1993, the idea of teleportation moved out of the realm of science fiction and into the world of theoretical possibility. It was then that physicist Charles Bennett and a team of researchers at IBM confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed.
• This revelation, first announced by Bennett at an annual meeting of the American Physical Society in March 1993
WHERE TELEPORTATION IS POSSIBLE:-
• TELEPORTATION will be explained with the following objects:
1. Experiments on photon
2. Human teleportation
3. Quantum teleportation
PHOTON EXPERIMENTS:-
• In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups, turned the IBM ideas into reality by successfully teleporting a photon, a particle of energy that carries light.
• The Caltech group was able to read the atomic structure of a photon, send this information across 1 meter (3.28 feet) of coaxial cable and create a replica of the photon
• In performing the experiment, the Caltech group was able to get around the Heisenberg Uncertainty Principle, the main barrier for teleportation of objects larger than a photon.
• This principle states that you cannot simultaneously know the location and the speed of a particle. In order to teleport a photon without violating the Heisenberg Principle, the Caltech physicists used a phenomenon known as entanglement
ENTANGLEMENT:-
• Entanglement means achieving the properties one photon by another photon.
• In entanglement, at least three photons are needed to achieve teleportation:
1. Photon A:The photon to be teleported
2. Photon B:The transporting photon
3. Photon C:The photon that is entangled with photon B
PRINCIPLE OF ENTANGLEMENT :-
• Two photons E1 & K and a beam spliters (it splits a light into two equal parts)are required
• We direct one of the entangled photons, say E1, to the beam splitter.
• Meanwhile, we prepare another photon with a polarization of 45 degree , and direct it to the same beam splitter from the other side, as shown.
• This is the photon whose properties will be transported; we label it K . We time it so that both E1 and K reach the beam splitter at the same time.
• The E1 photon incident from above will be reflected by the beam splitter some of the time and will be transmitted some of the time. Similarly for the K photon that is incident from below. So sometimes both photons will end up going up and to the right as shown
• Similarly, sometimes both photons will end up going down and to the right.
• However, in the case of one photon going upwards and the other going downwards, we can not tell which is which. Perhaps both photons were reflected by the beam splitter, but perhaps both were transmitted
HUMAN TELEPORTATION:-
• For a person to be transported, a machine would have to be built that can pinpoint and analyze all of the 10(to the power 28 ) atoms that make up the human body. That's a more than a trillion trillion atoms. This machine would then have to send this information to another location, where the person's body would be reconstructed with exact precision. Molecules couldn't be even a millimeter out of place, lest the person arrive with some severe neurological or physiological defect.
HOW IT BE POSSIBLE:-
• Teleportation would combining genetic cloning with digitization. In this biodigital cloning, tele-travelers would have to die, in a sense.
• Their original mind and body would no longer exist. Instead, their atomic structure would be recreated in another location, and digitization would recreate the travelers' memories, emotions, hopes and dreams. So the travelers would still exist, but they would do so in a new body, of the same atomic structure as the original body, programmed with the same information.

Pioneer of teleportation
What is Teleportation?

 Its the feat of making an object disintegrate in one place while a perfect replica appears some where else.
STEPS INVOLVED IN TELEPORTATION
 Scanning the object completely.
 Disassembling the object and sending all the information about the object.
 Reassembling the object from the information which was sent.
CLASSICAL FASCIMILE TRANSMISSION
CLASSSICAL TELEPORTATION

 Classical Teleportation taking Fax Machine as an example
HEISENBERG UNCERTAINTY PRINCIPLE
 Simultaneous measurement of the position and velocity of a quantum particle is not possible.
 Measurement of one value changes the other value.
QUANTUM TELEPOATATION
 One scans out part of the information from object A (the original).
 Two objects B and C are prepared and brought into contact (i.e., entangled), and then separated.
 At the sending station object B is scanned together with the original object A.
 While causing the remaining, unscanned, part of the information in A to pass, via EPR entanglement, into another object C.
 This scanned information is sent to the receiving station.
 Object A itself is no longer in its original initial state, having been completely disrupted by the scanning process.
ENTANGLEMENT
 It solves the difficulty of measuring that we encountered in Heisenberg Uncertianty principle.
 Two particles are said to be entangled when they come in contact.
 Measurement of one of the entangled sub-system puts the other sub-system in the corresponding state.
PRINCIPLE OF ENTANGLEMENT
 Two photon E1,K ,and a beam splitters are required
 We direct one of the entangled photons, say E1, to the beam splitter.
 Meanwhile, we prepare another photon with a polarization of 45 degree , and direct it to the same beam splitter from the other side, as shown.
 This is the photon whose properties will be transported; we label it K . We time it so that both E1 and K reach the beam splitter at the same time.
 The E1 photon incident from above will be reflected by the beam splitter some of the time and will be transmitted some of the time. Similarly for the K photon that is incident from below. So sometimes both photons will end up going up and to the right as shown.
 Similarly, sometimes both photons will end up going down and to the right.
 However, in the case of one photon going upwards and the other going downwards, we can not tell which is which. Perhaps both photons were reflected by the beam splitter, but perhaps both were transmitted.
 This means that the two photons have become entangled.
HUMAN TELEPORATATION
 Has considerable unresolved technical and philosophical issue such as..
 how to record human body accurately?
 can be able to reconstruct it?
 does it not violate continuity of existence?
DECOHERENCE
 Object’s quantum states degrade when information leaks to or from the environment (i.e., environmental noise) through stray interactions with the object.
 Introduces a certain level of error in the exchange of quantum information between the systems.
 Fundamentally Limits q-Teleportation.
RECENT SUCCESSFUL EXPERIMENTS IN TELEPORTATION
 In 1998 Physicist at CALTECH transported a photon across 3.2f of coaxial cable
 In 2002 , researchers at the AUSTRALIAN
NATIONAL UNIVERSITY transported a laser beam.
 In 2006,at the NIEL’S BOHR INSTITUTE ,DENMARK Dr. E.Polzik and his team teleported information stored in laser beam into a cloud of atoms
APPLICATION OF TELEPORTATION
 Quantum computer (computer that has data transmission rates many times faster than today's most powerful computers).
 Suspended animation (by creating a copy many years after the information was stored).
 Backup copies (creating a copy from recently stored information if the original was involved in a mishap.)
THINGS TO COMBAT..!
 Difficult to fathom what is future for human teleportation.
 Effects of the q-Teleportation process on the human consciousness, memories and dreams, and the spirit or soul.
 Consciousness, memories and dreams, and spirit/soul be successfully and accurately teleported or not?
CONCLUSION
 With the advancements, atoms of size 1012 are entangled and teleported.
 We are away from being able to teleport and entangle bulky objects( technical equipments, weapon platform, communication devices).

Introduction
Ever since the wheel was invented more than 5,000 years ago, people have been inventing new ways to travel faster from one point to another. The chariot, bicycle, automobile, airplane and rocket have all been invented to decrease the amount of time we spend getting to our desired destinations. Yet each of these forms of transportation shares the same flaw: They require us to cross a physical distance, which can take anywhere, from minutes to many hours depending on the starting and ending points.
But what if there were a way to get you from your home to the supermarket without having to use your car or from your backyard to the International Space Station without having to board a spacecraft? There are scientists working right now on such a method of travel, combining properties of telecommunications and transportation to achieve a system called teleportation.
The concept of teleportation was originally developed during the Golden Age of 20th century science fiction literature by writers in need of a form of instantaneous disembodied transportation technology to support the plots of their stories. Teleportation has appeared in such SciFi literature classics as Algis Budry’s Rogue Moon (Gold Medal Books, 1960), A. E. van Vogt’s World of Null-A (Astounding Science Fiction, August 1945), and George Langelaan’s The Fly (Playboy Magazine, June 1957). The Playboy Magazine short story led to a cottage industry of popular films decrying the horrors of scientific technology that exceeded mankind’s wisdom: The Fly (1958), Return of the Fly (1959), Curse of the Fly (1965), The Fly (a 1986 remake), and The Fly II (1989). The teleportation concept has also appeared in episodes of popular television SciFi anthology series such as The Twilight Zone and The Outer Limits. But the most widely recognized pop-culture awareness of the teleportation concept began with the numerous Star Trek television and theatrical movie series of the past 39 years (beginning in 1964 with the first TV series pilot episode, The Cage), which are now an international entertainment and product franchise that was originally spawned by the late genius television writer-producer Gene Roddenberry. Because of Star Trek everyone in the world is familiar with the “transporter” device, which is used to
teleport personnel and material from starship to starship or from ship to planet and vice versa at the speed of light. People or inanimate objects would be positioned on the transporter pad and become completely disintegrated by a beam with their atoms being patterned in a computer buffer and later converted into a beam that is directed toward the destination, and then reintegrated back into their original form (all without error!).
A few science fiction writers consider teleporters that preserve the original, and the plot gets complicated when the original and teleported versions of the same person meet; but the more common kind of teleporter destroys the original, functioning as a super transportation device, not as a perfect replicator of souls and bodies.
Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else.
It can save your organization time and money and enhance your internal and external communication network.
WHAT IS TELEPORTATION??
Teleportation is the transfer of matter from one point to another, more or less instantaneously. It is a recent phenomenon developed in the 1990’s. It is the 21st century alternative to travel
Etymology
The word teleportation was coined in 1931 by American writer Charles Fort to describe the strange disappearances and appearances of anomalies, which he suggested may be connected. He joined the Greek prefix tele- (meaning "distant") to the Latin verb portare (meaning "to carry"). Fort's first formal use of the word was in the second chapter of his 1931 book, Lo! "Mostly in this book I shall specialize upon indications that there exists a transportry force that I shall call Teleportation."
Definition
Teleportation is the process of moving from one place to another without travelling through the intervening space.
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.
History
In 1993 an international group of six scientists Richard Jozsa, Willian K. Wpploters, Gilles Brassard, Claude Crepeau, Asher Peres and IBM Fellow Charles H. Bennett, confirmed the intuitions of the majority of science fiction writers by showing that perfect teleportation is indeed possible in principle, but only if the original is destroyed.
This revelation, first announced by Bennett at an annual meeting of the American Physical Society in March 1993, was followed by a report on his findings in the March 29, 1993 issue of Physical Review Letters. Since that time, experiments using photons have proven that quantum teleportation is in fact possible.
In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups, turned the IBM ideas into reality by successfully teleporting a photon, a
particle of energy that carries light. The Caltech group was able to read the atomic structure of a photon, send this information across 3.28 feet (about 1 meter) of coaxial cable and create a replica of the photon. As predicted, the original photon no longer existed once the replica was made.
In subsequent years, other scientists have demonstrated teleportation experimentally in a variety of systems, including single photons, coherent light fields, nuclear spins, and trapped ions.
