Trapped-ion quantum network creates robust quantum memory.

Researchers at the University of Oxford have developed a robust quantum memory within a trapped-ion quantum network node that can store information for long periods of time despite ongoing network activity. The memory uses a combination of strontium and calcium ions to minimize crosstalk and detect errors in real-time. The team's demonstration of this quantum memory could be an important milestone on the ongoing quest to realize distributed quantum information processing and pave the way towards the creation of scalable quantum computing systems.
