Is Teleportation Really Possible?
Let me first define Teleportation: Teleportation is the transfer of matter from one point to another in ideally no time.
Initially the attention towards teleportation was mainly dragged by Star Trek series. Everyone wondered if it could be practically possible. In the beginning scientist ignored this fact as they thought it would violate many laws of quantum physics but somehow they turned their eyes towards this amazing and distant dream. The famous line in Star Trek for teleportation was “beaming up” so we can say beaming people is not what is expected from teleporting but just passing the information.
Teleporting light or single atom is commonly known and has been done successfully but teleporting both light and matter was a breakthrough introduced by proff. Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark using laser beam. To explain the concept of teleportation simply, we can say that it is the process of completely scanning the object to be teleported and then disintegrating or destroying it from original position after it is created at the new desired position. According to the uncertainty principle the location and speed of the particles simultaneously cannot be known exactly. So while scanning the object to be teleported, more precisely it is scanned more it gets disturbed and so we cannot have the complete information to make perfect replica.

In 1993 the research team of IBM under the physicist Charles Bennett theoretically confirmed that quantum teleportation was possible. The new theory explained by them was entanglement. This theory was based on observations of Einstein-Podolsky-Rosen.
Atleast 3 photons are required for this.
Photon A – Photon to be teleported.
Photon B- The transporting photon.
Photon C- The photon that is entangled with photon B.
Initially photon B and Photon C are entangled (brought in contact). Photon B is taken towards photon A and photon C is taken towards receiving station. Now photons A and B are scanned together and the information is sent towards the receiving station meanwhile photons A and B are disrupted. Now at receiving station using the scanned information and after several treatments on photon C the exact replica of A is created.
