We have already discussed teleportation in previous blog — it is transfer of information from one place to another by using what is known as quantum entanglement.
There is a pathbreaking achievement in quantum teleportation. Quantum teleportation transfers information instantly and over any distance. At Northwestern University, Illinois, US, researchers demonstrated quantum teleportation over optic fiber cable (OFC).
This is achieved through quantum entanglement — an invisible twin connection between two particles linked in such a way that what happens to one affects the other, even if the particles are miles apart. You are not sending physical objects. You are sending the state or condition of the particle.
It is so exciting. It was unthinkable. It paves the way for next generation quantum and classical networks sharing the same OFC infra. It pushes quantum communications to the next level.
The experiment chose the delicate quantum information carried by photos. It should survive the clutter of internet data. They utilized, therefore, a specific wavelength of the quantum signal. There were filters to prevent interference from other data streams.
The photons were placed at a judicial point so that there is least scattering. There was no interference from the classical channels which were present.
They successfully teleported quantum state of light. It is a big leap forward since it integrates quantum communication to existing internet work. It is not just a simulation. It happens in real-world situation.
It occurs at the speed of light. It is a step to quantum internet. It could revolutionize traditional computing. The technology has immense potential.
