Teleportation?

Only on the quantum level

The transporting of objects and personnel has long been a bane in the exploration of space. Large, heavy lift vehicles are needed to overcome the gravitational forces associated with orbital flight. Research has been conducted in the area of teleportation (a means of moving an object from one place to another without the need of a vehicle), which is a means by which an object is scanned down to its molecular level. This information is then digitally stored and then transmitted to another device in a distant location where it is then 'reconstructed'. In the final decade of the twentieth century, technology had advanced to a level where quantum mechanics could be used to conduct experiments in the area of 'quantum teleportation'. At first, quantum mechanics seems to make such experimentation impossible. This due to the Heisenberg Uncertainty Principle, but quantum mechanics itself, proved the solution. There is a peculiar (but fundamental) feature of quantum mechanics, referred to as 'entanglement' which has been used to circumvent the limitations set forth by the Uncertainty Principle without violating it. At present, we are far from the ability to transport an object or a human, but the teleportation of light particles (or photons) has been demonstrated in the lab. It is through the use of these 'entangled' photons that our 'transporter' works; In the lab, a short pulse of ultraviolet laser light is focused on a crystal. This pulse produces an entangled pair of photons; the most effective way for this to occur is through spontaneous parametric down-conversion. However, the consequential outcome of this experiment is the production of 'copies'. Suffice it to say that, though one hurdle in the creation of 'teleportation' has been overcome, there is much yet to be learned before the 'transporter' becomes a reality (if ever), yet many have said the same for items we now take for granted. Further research will be needed and greater advances in technology, but we may yet (one day) see such made reality.
