Researchers from the University of Jena in Germany have demonstrated the concept of quantum teleportation in a classical world experiment for the first time.
Led by physicist Dr. Alexander Szameit, the team used a special laser beam technique to entangle information in light beams and transmit that information instantly, without any loss of time. This instant exchange of information, mimicking the properties of quantum teleportation, had never been achieved before outside the quantum realm until now. The promise of instant information transfer has broad implications across many industries, especially telecommunications and semiconductors.

In the quantum world, it’s possible to transmit information from one location to another without any loss of time. The process, known as quantum teleportation, was first proposed in the early 90s and our understanding has come a long way since. Quantum teleportation is not a form of transportation, but of communication. It provides a way of transporting a particle (or qubit of information) from one location to another, without having to move a physical particle along with it.
“As can be done with the physical states of elementary particles, the properties of light beams can also be entangled,” said team member Dr Marco Ornigotti also at the University of Jena. “You link the information you would like to transmit to a particular property of the light.”
For the experiment, the researchers entangled information in a particular polarization direction of a laser beam. Once they knew where the information was codified, they were able to observe the instant transmission of information within the system. Scientists verified the information is transmitted fully and instantly, without any loss of time, obeying the theoretical framework of quantum teleportation.
The findings are likely one of the first steps in a long innovation process for understanding how quantum teleportation could be used in macro environments. Demonstrating that quantum teleportation is possible in the classical world could change everything if scientists can learn to harness its functionality.
