Web29. dec 2024. · By combining this long-lived optical memory with high-speed trains (with a speed of 300 km/h), this scheme provides significantly enhanced data rate as compared to that relying on direct transmission in telecom optical fibers, leading to a promising future for large-scale quantum communication based on transportable quantum memories. Quantum information can be encoded into various degrees of freedom of photons, such as frequency, time and polarization. The time-bin encoding has the particular advantage of good robustness to environmental fluctuations. Therefore, here we implement the coherent light storage with time-bin-like … Pogledajte više In order to implement optical storage in a ZEFOZ field, the knowledge of the energy level structures in both the ground and excited state is … Pogledajte više The experimental sequence is shown in Fig. 2a.
