Prior to this, teleportation experiments had only been demonstrated between locations that were limited to a distance on the order of kilometers. The team also demonstrated advancements in their data transmission abilities at greater distances and with better encryption.
More recently, researchers extended entanglement to electrons by making qubits from individual electrons. This in particular has been challenging compared to using photons — which naturally propagate over large distances — because electrons are confined in space. These types of studies pave the way to explore quantum teleportation in all spin states of matter. Similar to the way in which we scoff at the first room-sized computers unveiled in the s, we may one day look at our current binary computers in the same way.
Although we are still far off from this new world built on the mind-bending principles of quantum mechanics, we are on the verge of unlocking incredible new capabilities that will provide endless possibilities. Computer Science Physics. And remember how the slightest disturbance ruins quantum entanglement? The process of reassembling your atoms would inherently scramble the information. Kirk might as well put on a red shirt first. The teleportation situation becomes much less bleak if you bend the definition a bit, however.
As many a video game player has noticed, the human brain has a remarkable ability to project itself outside the body and into other objects or virtual spaces. A mechanical astronaut will soon be strolling outside the International Space Station. In the near future, you might be able to experience space exploration vicariously through a Mars rover or mechanical arms poking at a distant asteroid.
Biotech guru J. Craig Venter proposes that if we find microbial life on Mars, we could sequence its genome locally, transmit the information and rebuild the organism here on Earth. In principle, Venter notes, the process could go the other way: It would be possible to send human DNA, along with an appropriate incubator, to distant planets and synthesize people at the other end.
Then your clone could start setting up shop on a world orbiting Alpha Centauri B. But if you accept that information is the only thing that defines your mind, the task seems feasible. No longer do you need to assemble atoms meticulously in the right locations; just the facts will do. Note a fascinating common thread through all these possibilities. Whether you regard yourself as a pile of atoms, a DNA sequence, a series of sensory inputs or an elaborate computer file, in all of these interpretations you are nothing but a stack of data.
According to the principle of unitarity, quantum information is never lost. Put them together, and those two statements lead to a staggering corollary: At the most fundamental level, the laws of physics say you are immortal. Quantum teleportation involves two distant, entangled particles in which the state of a third particle instantly "teleports" its state to the two entangled particles.
Last year, scientists confirmed that information could be passed between photons on computer chips even when the photons were not physically linked. Now, according to National Science Foundation -funded research by University of Rochester and Purdue University scientists, teleportation may also be possible between electrons. In a paper published in Nature Communications and one to appear in Physical Review X , the researchers, including Rochester physicists John Nichol and Andrew Jordan, explore new ways of creating quantum-mechanical interactions between distant electrons.
