So what is teleportation ?
Teleportation is the transfer of an object from any point in space to any other
point in the space. So basically teleportation involves disintegration of an
object in a teleportation device and sending the information across vast
distances. At the destination, the teleportation machine interpret the
information sent and reintegrate the object.
So is teleportation
possible ? Teleportation experiment carried out previously, was able to
teleport a photon up to 100 km on ground. After 100 km a photon get scattered
due to limits in fibre optic cables. However researchers in China were
successfully able to teleport a photon from the ground to a satellite at a
distance varying from 500 to 1400 km. Micius is a satellite that was launched
by China and is a highly sensitive photon receiver. Entangled pair of photons
was created on ground and one of the photon was beamed to the satellite. The
quantum state of the entangled pair of photons was then studied to understand
‘spooky action at a distance’ i.e. the researchers carried out teleportation of
photons. By affecting the quantum state of earth photon, the quantum state of satellite
photon was changed, thus the photon responsible for change in quantum state, was
teleported to the satellite.
The principle of quantum
entanglement involved in teleportation has much wider application. Firstly, it
can be used in encryption. The quantum entanglement creates a pair of photons.
Any action to manipulate the information will cause an effect on the other
member of the pair and will let the end user know that the information was
compromised. Secondly, the quantum computer and quantum network is based on
quantum principle. Thirdly, human teleportation is a future possibility.
However teleportation
technology also has its sets of problems. Firstly, teleportation involves
integration and disintegration of matter, and only information is transferred.
In a way the original is destroyed and a new one is created. So can it
disintegrate a living being and reintegrate it back with life ? This is a big
question to which we have no answer, as of now. Secondly, would it mean a
faster than light travel ? Although only our information travel but the concept
is not yet fully understood. Thirdly, if we somehow manage to teleport a living
being, but will the teleported person be the real person himself. Fourthly, as
‘no cloning will be allowed’ so if our information collected before our
disintegration gets corrupted then there is a high chance that we will never
ever materialize.
