Quantum Teleportation is one of the newest areas of study in the field of quantum physics. It is the stuff of science fiction, which is fast becoming reality, where solid objects can be moved vast distances instantly. It has been the subject of books and movies for years but it wasn’t until recently that physicists at IBM’s laboratories made it a reality.

The ideas that formed the basis of these experiments came about from previous research by scientists such as Albert Einstein and Heisenberg. This essay will explore the research done on this subject, the theories behind it, and the possible applications.

Quantum teleportation is the idea that transporting matter can be achieved instantaneously by taking advantage of certain aspects of quantum physics. It is not possible to actually transport the matter, but rather, the properties of the object being transported can be applied to matter in a separate location. This newly created object is identical to the original down to the state of the individual atoms, and so is in effect the same object. The original object loses its properties during the process and is, in effect, destroyed.

This takes advantage of the Einstein-Podolsky-Rosen correlation (Quantum), also referred to as entanglement. When two particles are entangled they take on properties identical to each other regardless of separation. This means that if something alters one of the entangled pair it affects the other in the exact same manner. In order to transport something we have to start with one of these entangled pairs. One particle at the source location and one at the location we want to transport the new object to. We then take a third particle, which is what will be transported, and measure it in relation ...

... in the field of computing. Because computers operate on a binary system it is possible that individual quanta cold be used to store information. This is possible because quanta can be in two states, horizontal and vertical. Using quantum teleportation information can instantly be sent from one point to another. An example of quantum computing could be if a person had to search a dorm for a specific item. Normally the person would have to go to every door in turn and look inside but if this were a quantum computer doing the searching it could look in every room at the same time.

  • Essay On Alice In Quantumland

    1054 Words  | 3 Pages

    Alice finds herself in a place named Quantumland. In Quantumland, each attraction demonstrates something different used in science. To be able to understand Quantum Land, Alice is told she must first has to travel to the Heisenberg Bank. She began asking questions, when a guard tells Alice she can’t skip in line. She quickly becomes confused because she is not standing in a line. She then saw electrons begin to morph together and others vanish. The Bank Manager begins to explain to Alice that the bank is in charge of distribution of energy loans to all virtual particles. In order for a particle to exist it must have a certain minimum energy, called its rest mass energy (Gilmore 14). The electrons are about to get loans of energy from the Heisenberg Bank which allows them to exist for

  • An Adventure of the Quantum Universe in Alice in Quantumland by Robert Gilmore

    1549 Words  | 4 Pages

    The novel, Alice and Quantum Land, by Robert Gilmore is an adventure in the Quantum universe. Alice, a normal teenage girl, goes through quantum land and understands what quantum is and how it works. The quantum world is a difficult one to understand, as its nature is one of complex states of being, natures, principles, notions, and the like. When these principles or concepts are compared with the macro world, one can find great similarities and even greater dissimilarities between the world wherein electrons rule, and the world wherein human beings live. In Alice in Quantumland, author Robert Gilmore converts the original tale of Alice in Wonderland from a world of anthropomorphic creatures into the minute world of quantum mechanics, and attempts to ease the reader into this confusing world through a series of analogies (which comprise an allegory) about the principles of quantum mechanics. Through Alice’s adventure she comes across some ideas or features that contradict real world ideas. These ideas are the following: Electrons have no distinguishing spin, the Pauli Exclusion Principle, Superposition, Heisenberg Uncertainty Principle, and Interference and Wave Particle Duality.

  • The Quantum Brain: Theory or Myth?

    888 Words  | 2 Pages

    The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.

  • Einstein on Quantum Mechanics

    938 Words  | 2 Pages

    Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.

  • The Heisenberg Uncertainty Principle

    758 Words  | 2 Pages

    Werner Heisenberg was the first to realize that certain pairs of measurements have an intrinsic uncertainty associated with them. For instance, if you have a very good idea of where something is located, then, to a certain degree, you must have a poor idea of how fast it is moving or in what direction. We don't notice this in everyday life because any inherent uncertainty from Heisenberg's principle is well within the acceptable accuracy we desire. For example, you may see a parked car and think you know exactly where it is and exactly how fast it is moving. But would you really know those things exactly? If you were to measure the position of the car to an accuracy of a billionth of a billionth of a centimeter, you would be trying to measure the positions of the individual atoms which make up the car, and those atoms would be jiggling around just because the temperature of the car was above absolute zero!
