Scientists Have Successfully Achieved The First-ever "Teleportation" Of Images Using Quantum Technology [View all]

Scientists have showcased a new method for transmitting images across a network without physically sending the image. This advancement could lead to the development of a quantum internet capable of managing high-dimensional entangled states.

The study, published in Nature Communications, was carried out by a global team from the University of the Witwatersrand, Johannesburg, and ICFO – The Institute of Photonic Sciences, Spain. They employed a method known as quantum state transfer, which entails transferring the quantum characteristics of one system to another, without transmitting any physical particles.

The team demonstrated the encoding of images in the quantum states of two entangled photons, which maintain a quantum connection even when separated. By measuring one photon, the other photon can be instantly manipulated to recreate the image, regardless of the distance between them.

This is akin to the concept of quantum teleportation, which has previously been demonstrated with single photons or qubits, the fundamental units of quantum information. However, the team set a new record by transmitting images with 15 dimensions of information, using only two photons as a quantum resource.

“Traditionally, two communicating parties physically send the information from one to the other, even in the quantum realm,” says the lead PI from Wits University. “Now, it is possible to teleport information so that it never physically travels across the connection – a ‘Star Trek’ technology made real.”
