Russian national operator Rostelecom, in cooperation with its subsidiary regional operator Tattelecom and the Kazan Tupolev R&D University of Technology, has tested quantum encryption technology. The operators exchanged quantum encryption keys on a 143-km section of the fibre-optic network. Rostelecom claims that it is the longest distance achieved in such tests on commercial networks. In 2018, the national operator tested similar technology on a 58-km network section.   ...  

Princeton University has announced the creation of the Princeton Quantum Initiative to foster research and training across the spectrum from fundamental quantum science to its application in areas such as computing, sensing and communications. The new initiative builds on Princeton’s world-renowned expertise in quantum science, the area of physics that describes behaviors at the scale of atoms and electrons. Quantum technologies have the potential to revolutionize areas ranging from secure data...  

Quantum computing has the potential to revolutionize technology, medicine, and science by providing faster and more efficient processors, sensors, and communication devices. But transferring information and correcting errors within a quantum system remains a challenge to making effective quantum computers. In a paper in the journal Nature, researchers from Purdue University and the University of Rochester, including John Nichol, an assistant professor of physics, and Rochester PhD students...
