INTRODUCTION
Teleportation is the ability to decipher or move or transmit objects into atoms from one place to another and rearrange them without having to travel long distances.
Quantum Teleportation is the process by which quantum information can be transmitted from one place to another using photon particles, with the help of classical communication and quantum involvement between the sender and receiver. It relies on classical communication, whose process can not be faster than the speed of light.
In other words, Quantum Teleportation is the latest technology that was successfully created to move objects from one place to the desired destination by using photons.
HISTORY
Previously, have you ever seen Star Trek movies before? If you've ever, definitely remember the same teleport technology or removal of objects from the Star Trek spacecraft to other places. In other films also now have started many who use such technology.
Since the wheel was discovered more than 5,000 years ago, people have found a new way to travel faster from one point to another. Trains, bicycles, cars, planes and rockets have all been created to reduce the amount of time we spend to the destination we want. But each form of transport shares the same flaw: They need us to traverse the physical distance, which can last from minutes to hours depending on the starting and ending points.
In 1993, the idea of teleportation moved from the realm of science fiction into the real world. It was then that physicist Charles Bennett and his team at IBM asserted that quantum teleportation is possible, but only if the original object being removed is destroyed. It was first announced by Bennett at the annual meeting of the American Physical Society in March 1993, followed by a report of its findings in the March 29,193 Physical Review Letters. Since then, experiments using photons have proven that quantum teleportation is actually possible.
In 1998, physicists at the California Institute of Technology (Caltech), along with a team from Europe, turned the idea of IBM into reality by successfully teleporting photons, particles of energy in light.
Subsequent experiments, the Caltech team successfully overcame Heisenberg's uncertainty principle, the biggest hurdle in teleportation of larger objects of photons. This principle says that we can not know the location and velocity of particles together. But surely we will have difficulty how to teleport it if we can not know the position of a particle. To teleport photons without violating the Heisenberg principle, Caltech physicists use a phenomenon called Entanglement.
Well, that was the history of the invention and research conducted similarly a number of experts and experts who are still tuh still trying to do various research as an attempt to find a way out to be able to teleport a larger scale, for example humans.
Quantum Teleportation
Starting from Quantum Communications which is a communication technology that takes the principle of Quantum to transmit information. Currently, the one used to transmit data is
photons. The media it wears can be fiber optic.
Quantum teleportation can not be used to copy the system, because it violates the theory
no-cloning. But the greatness of this tool is able to create a replica of any object, to the smallest part that is difficult to reach. Although the name is inspired by teleportation commonly used in fiction, it does not provide the same way teleportation to fiction. While it is possible to move one or more qubits (quantum bits) of information between two atoms, this technology has not been able to reach molecular or greater scales. One might think that teleportation is a form of transportation or some kind of communication; this quantum teleportation provides a means to move the qubit from one location to another without having to move its physical shape.
WAYS OF WORKING
Teleportation involves dematerializing an object at one point, and sending details of the atomic configuration that places the object to another location, where it will be reconstructed.
The principles used in the Star Trek movie:
Mr. Spocks of cell particles are altered, made to spin faster, decoded and transferred to the destination. Once there, he is encoded so that it can be intact again. The difficult thing to do is how the process of encoding and making is done, so there is no change in the structure of the object it sends.
The process is as follows:
- A pair of EPRs is generated, one qubit sent to location A, the other to location B.
- At location A, Bell calculations on one ubed pairs of EPR and ubed pitched qubits will result in one of four possibilities, which can be encoded in two classical bits of information. Then all the qubits at location A are discarded.
- Using classical channels, two bits are sent from A to B.
- As a result of measurements made at location A, the EPR qubit pair at location B is one of four possible states. Of these four possible circumstances, one is identical to the original quantum state, and the other three are strongly related. Knowing that, the qubits at location B are modified in one of three ways, or not at all, to produce an identical qubit where the qubit is selected for teleportation.
In short, the quantum on the object is destroyed and recreated, therefore quantum teleportation can not move objects alive or die physically entirely. This tool 'creates' a replica of the previous object in a position elsewhere and the previous object will 'disappear' during the replica being created.
NOTES AND RESEARCH RESULTS
The Caltech Group managed to read the atomic structure of the photons, sending this information over 3.28 feet (about 1 meter) of coaxial cable and creating a replica. As expected, the original photon no longer existed after the replica was made.
In June 2002, an Australian physicist, Ping Koy Lam, teleported a laser beam. Laser rays consisting of billions of photons, by Lam measured the velocity of the particle, shape, and polarization, to then be reshaped using a set of photons elsewhere.
In early August 2004, teleportation distance reached 600 meters.
In 2010, some researchers from the University of Science and Technology of China in Shanghai, China, managed to make teleportation on the first try they have moved photons from where they work to a place as far as 97 kilometers. The researchers used a 1.3 Watt laser and several optics for the launcher as well as the receiver. In the experiment, scientists managed to send 1100 photons to a distance of 97 kilometers in just 4 hours.
In April 2011, researchers reported that they had successfully teleported light wave packets up to 10 MHz bandwidth.
In May 2012 the longest distance of quantum teleportation reaches 143 km (89 miles) with photons between the Canary Islands, La Palma and Tenerife off the Atlantic coast, north Africa; and 21 m with the system material.
In August 2013, quantum teleportation is already using hybrid technology.
On May 29, 2014, researchers announced possible ways to transfer data with quantum teleportation.
Researchers at Niels Bohr Institute successfully used quantum teleportation to transmit information between atoms of gas clouds.
IMPACT
Despite delivering large amounts of photons to distant sites, researchers are still continuing to develop this teleportation technology so that it can later be used to move objects that have a big time, such as humans.
If the technology is successful, then the presence of motor vehicles will be trimmed away, because it is certain that many will use this technology to travel to a place quickly without having to get congested or other road problems.
CONCLUSION.
this technology is in waiting by the whole world can but all this is very expensive. later surely can perfection
