3. 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. Bicycle,Bus,Train,Aireoplane ,….. The above require physical distance where it can take lot of time to travel. • 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 phenomenon called teleportation

4. Once imagine if there is a chance that we can travel from one place to another place without covering the actual physical distance.

5. What is Teleportation ? 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. 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

6. Any real examples for Teleportation

7. 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. 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.

8. Heisenberg Uncertainty Principle This principle states that you cannot simultaneously know the location and the speed of a particle. The more accurately an object is scanned, the more it is disturbed by the scanning process ,until one reaches a point where the object’s original status has been completely destroyed ,still that we cannot make a perfect replica. In order to teleport a photon without violating the Heisenberg Principle, the Caltech physicists used a phenomenon known as entanglement.

9. ENTANGLEMENT Entanglement means achieving the properties one photon by another photon. In entanglement, at least three photons are needed to achieve teleportation: Photon A:The photon to be teleported Photon B:The transporting photon Photon C:The photon that is entangled with photon B

10. If researchers tried to look too closely at photon A without entanglement, then the photon will be destructed because of full scanning. By entangling photons B and C, researchers can extract some information about photon A, and the remaining information would be passed on to B by way of entanglement, and then on to photon C. When researchers apply the information from photon A to photon C, they can create an exact replica of photon A. However, photon A no longer exists as it did before the information was sent to photon C.

11. This six 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, 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, not replication.

12. Teleportation of Photon As the figure above suggests, the unscanned part of the information is conveyed from A to C by an intermediary object B, which interacts first with C and then with A.

13. In quantum teleportation two objects B and C are first brought into contact and then separated. Object B is taken to the sending station, while object C is taken to the receiving station. At the sending station object B is scanned together with the original object A which one wishes to teleport, yielding some information and totally disrupting the state of A and B. The scanned information is sent to the receiving station, where it is used to select one of several treatments to be applied to object C, thereby putting C into an exact replica of the former state of A

14. Real Teleportation Experiments In 2002 the Australian national University team successfully teleported a laser beam. In oct 4 2006 at the Niels Bhor Institute in the Copenhagen,Denmark Dr.Polizik and his team Successfully teleported the information present in the beam in to a cloud of atoms. It involves teleportation between light and matter. The  Philadelphia Experiment  is an alleged military experiment supposed to have been carried out by the  U.S. Navy  at the  Philadelphia Naval Shipyard  in  Philadelphia ,  Pennsylvania ,  United States , sometime around October 28, 1943.  The destroyer escort  USS  Eldridge  was rendered invisible, teleported to  New York , teleported to another dimension where it encountered aliens, and teleported through time, resulting in the deaths of several sailors

15. Real Applications Quantum Cryptography Quantum Cryptography allows the transmission of with 100% security ensured by the law of physics .these are the potential applications for the military and commerce. Quantum Computation computer Performance, memory and functions are increasing for every 18months as the size remains same means we are expecting more and more with the fewer and fewer atoms .Eventually classical physics is no longer exists.

16. How hard is it to teleport a human? 1.There is about 10 (1,000,000,000,000,000,000,000,000,000) atoms in a person. 2.With 100 parameter pairs per atom, that’s about 10 pair of information. 3. So far we have done 1 pair, so a human is about 10 times harder.

17. Conclusion But like all technologies, scientists are sure to continue to improve upon the ideas of teleportation, to the point that we may one day be able to avoid such harsh methods. • One day, one of our descendents could finish up a work day at a space office above some far away planet in a galaxy many light years from Earth, tell his or her wristwatch that it's time to beam home for dinner on planet X below and sit down at the dinner table as soon as the words leave his mouth
