Scientists have demonstrated a new way of transporting images across a network without physically sending the image. This breakthrough could pave the way for a quantum internet that can handle high-dimensional entangled states. The research, published in Nature Communications, was conducted by an international team from the University of the Witwatersrand, Johannesburg, and ICFO – The Institute of Photonic Sciences, Spain. They used a technique called quantum state transfer, which involves transferring the quantum properties of one system to another, without sending any physical particles. The team showed how images can be encoded in the quantum states of two entangled photons, which share a quantum link even when they are separated. By measuring one photon, the other photon can be instantly manipulated to recreate the image, regardless of the distance between them. This is similar to the concept of quantum teleportation, which has been demonstrated before with single photons or qubits, the basic units of quantum information. However, the team achieved a new record by transporting images with 15 dimensions of information, using just 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.” The team also used a novel detector that can measure multiple properties of a photon at the same time, without the need for additional photons. This detector, developed by ICFO, enabled the team to perform the quantum state transfer with high fidelity and efficiency. The ability to transport high-dimensional quantum states could have significant implications for the future of quantum communication and computing. Quantum networks based on high-dimensional entangled states could offer higher information capacity, security and robustness than current systems. The team hopes to further develop their technology and explore its applications in various fields, such as biomedicine, metrology and cryptography. They also aim to increase the dimensionality and complexity of the quantum states they can transport, as well as the distance they can cover.
My usual response when someone says something indecipherable. The content is far above my education level.
In that case, you're either too self-important to bother with anything other than yoruself or just plain lazy as some of those here who can't even invest 10 minutes of their life watching a YouTube video to educate themselves. Speaking of which, here's a short video explaining Quantum Entanglement in simple terms.
