Quantum computing is a fascinating and continually developing field that may drive computers' future and fundamentally change the world. While that is happening, people still need networks to communicate over the internet. As such, scientists with Fermilab and other research institutes have been applying quantum physics to networking to create quantum teleportation over fiber optic cable. As the researcher’s report states, “The goal of a quantum network is to distribute qubits between different locations, a key task for quantum cryptography, distributed quantum computing, and sensing.” This quantum network can form the backbone of a future quantum internet, where security...

Beam me up, Scotty. Scientists have recently announced that they have achieved complex quantum teleportation. Multidimensional teleportation could have a strong impact on quantum computing and communication. Researchers from the Austrian Academy of Sciences, University of Vienna, and University of Science and Technology of China successfully teleported a three-dimensional quantum state. They were able to teleport the quantum state of a photon or light particle to another. Scientists have theorized that this kind of transportation is possible since the 1990s, but have not been able to prove it. Teleportation does not transport matter, but instead moves quantum information. The scientists were... Read more...
"Beam me up, Scotty!" Chinese scientists just set a record for quantum entanglement distance, and many argue that this experiment expands the possibilities for global quantum communication. The Chinese team of scientists, led by Ji-Gang Ren at the University of Science and Technology in Shanghai, fired a laser from a station in Tibet to a satellite 1,400 kilometers (870 miles) above the Earth’s surface. The laser that went to the satellite carried a photon that was entangled with another photon that remained on the ground. The scientists then entangled a third photon and measured their quantum states. Image from: Wikimedia Commons, Maksim“Entangled” photons have what Albert Einstein referred... Read more...
