A new quantum computing study claims that a recent finding in the production, storage and retrieval of"quantum data" has brought us one step closer to the quantum internet.
These quantum memory devices could receive, store and retransmit qubit states. The new study, conducted at Imperial College London, the University of Southampton, and the Universities of Stuttgart and Wurzburg in Germany, claims to have achieved this using standard fiber optic cables for the first time. The findings were published April 12 in the journal Scientific Advances.
Thomas said that using nonlinear optics is less reliable — a pair of usable photons isn't produced every time, whereas a single emitter quantum dot produces them at a higher rate. The next challenge is that the efficiency of the interface between quantum memory devices depends on matching both the wavelength and bandwidth. Discrepancies here make storage and retrieval too inefficient, but the study finally bridged the gap.
Quantum network models are more stable at extremely low temperatures, which limits their real-world applications, but the study achieved a stable connection at room temperature, which puts it within reach of real-world use.
