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).
