Teleportation is considered science fiction — travelling at great speed to the next location. This fiction has become a reality between two supercomputers. It is one of the holy grails of quantum physics. The quantum information is teleported. At the core of quantum teleportation is the concept of entanglement. Here two particles are so close to each other, despite their being away from each other. The state of one influences the other particle immediately. Einstein called this ‘spooky action at a distance’. It is not seen, but it can be felt. The effect could be witnessed. Spooky means ghost. Entanglement is used to teleport the state of a single qubit (the quantum equivalent of a bit). The teleportation is from one quantum processer to another.
In classical computers, the information is transferred by physical travel through wires or fibers. Entanglement does this — it reconstructs information on the other end. It is a leap for mankind.
Quantum communication can transform what is already known. Transfer of huge data quickly through machines all across the world. This is what could be achieved through qubits teleportation between supercomputers.
Ions were manipulated by Oxford scientists in electromagentic fields. The teleportation process works out depending on the control that entaglement has over the states of ions.
It is a milestone development for information sharing and processing. It could give birth to quantum internet. It breaks global barriers.
