Teleportation or Quantum teleportation is a process by which quantum information and atoms of a particular object can be transferred from one location to another. This has been seen in many movies and television series like Star Trek and Jumper. Surprisingly, teleportation may now be a reality. Scientists at the Delft University of Technology in the Netherlands were able to successfully teleport a diamond three metres across the room.
So how was it done?
In Prof Hanson’s experiment, three entangled particles which were a nitrogen atom and two electrons were entangled in a diamond and locked. These were used to transfer spin information a distance of three metres.
Four possible states were transmitted, each corresponding to a ‘qubit‘, the quantum equivalent of a digital ‘bit‘.
Each ‘bit‘ of information in a classical computer represents one of two values, normally zero or one.
But a ‘qubit‘ can represent a zero, a one, or a ‘superposition‘ of both states at the same time.
It is said that there is no law of physics that prevents teleportation, therefore, to rule out its possibility is a very risky thing to do. However, human teleportation is still a thing of the far away future and not possible as of yet. What the Dutch physicists have performed involves quantum entanglement, which Albert Einstein once described as “spooky action at a distance,” a term that very well describes what it is. In quantum entanglement, particles, basically, remain connected in a way that whatever is done to one particle is also experienced by the one it is connected to.
This demonstration is an extremely important step to develop a fast internet-like relation between ultra-fast quantum computers whose processing power is extremely low in comparison to that of today’s supercomputers. The researchers have already planned new experiments to move ahead with the idea of teleportation. A more ambitious experiment, involving the teleportation of information between buildings on the university campus which will be 1,300 metres apart, is planned in July. It is hoped this will answer Einstein’s main objection to teleportation, that of the possibility that a signal passes between entangled particles at the speed of light.
Professor Hanson of Delft University feels that this experiment will be a huge technical challenge as nobody has performed this before.
Thus, definitely as exciting as it seems, human teleportation could be real in the coming future.
