A team of scientists demonstrated fast photon-mediated entanglement between trapped ions, an advance that the team reports is a major step forward in quantum networking, among other quantum technologies.
The experiment, led by the Duke Quantum Center, achieved a record in entanglement rates between two barium ions while employing ytterbium ions for continuous sympathetic cooling. The results, published in Physical Review Letters and an earlier version on ArXiv, suggest promising advances toward scalable quantum networks, which are critical for the future of not just quantum computing, but also communication and sensing.
