Quantum theory supported by many experiments reveals that the quantum connection between two particles can persist even if they are countless light years away from each other.
A class of experiments performed during the last few decades has shown that something we do in one particular place (such as measuring certain properties of a particle) can be somehow connected with something that happens in another potentially far distant place (such as the outcome of measuring certain properties of another distant particle), without anything being sent from here to there.

In May 2014, a New York Times report stated that physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.
What does this have to do with synthetic diamonds and electronics?
Synthetic diamond has become useful in solid-state electronics. Companies like Element Six grow high purity, single crystal, synthetic versions of diamond with an added twist of strategic doping (inserting certain impurities) that can turn the diamond insulator into a semiconductor. This hybrid has been shown to be able to detect ultraviolet light, to create UV LEDs and high-power microwave electronics.
The most unusual effect that has been discovered is “quantum spintronics,” which scientists believe could lead to ultra-secure communications. Spintronics is not new to electronics, just look inside the hard-drive in your PC. The giant magneto-resistive effect can detect microscopic domains on a disk, which represent 1s and 0s comprising the data it contains.
Used in quantum computing, synthetic diamond can be used as quantum bits or qubits (analogous to 1 and 0 in classical computers). Qubits can have an infinite number of values instead of being confined to a mere 1 or 0. This effort could bring quantum computers into reality. (See Figure 1.)

Essentially, the spin rate and direction of one particle can simultaneously determine the spin rate and direction of its “entangled” partner on the other side of the universe. Researchers use laser light to entangle two electrons trapped inside small synthetic diamonds.
What about teleportation?
Quantum teleportation cannot move atoms, but it can transfer information about the state of an atom or particle from one place to another without that information moving in between.
The information to be teleported is encoded in a nearby nitrogen atom that is also trapped inside the diamond crystal.
Researchers have measured the state of the atom and its neighboring electron and sent the measurement to the distant location. The original information is destroyed but not transmitted, so it is safe from interception or eavesdropping.
The measurements are used to determine what type of manipulation should be performed on the distant entangled electron to recreate the encoded information. The information is considered “teleported” because it did not travel the distance between the two locations.
As mentioned in many of the Star Trek episodes, “Beam me up, Scotty!”
Is this just science fiction or do you think this is possible in the near future? Please share your thoughts and experiences.
