Heralded entanglement distribution between two absorptive quantum memories.

Owing to the inevitable loss in communication channels, the distance of entanglement distribution is limited to approximately 100 kilometres on the ground. Quantum repeaters can circumvent this problem by using quantum memory and entanglement swapping. As the elementary link of a quantum repeater, the heralded distribution of two-party entanglement between two remote nodes has only been realized with built-in-type quantum memories.

Anti-hemorrhoidal activity of Lian-Zhi-San, a traditional Chinese medicine, in an experimental hemorrhoidal model in rats.

Objective: Hemorrhoidal disease (HD) is the most common proctological disease, with an estimated prevalence rate of 4.4%, and a peak in individuals between 45 and 65 years of age. This study was done to evaluate whether Lian-Zhi-San (LZS), a clinically used anti-hemorrhoidal ointment could alleviate the inflammatory injury, with its associated changes of inflammatory cytokines and morphology of anorectal tissues, in an experimental model of HD in rats.

Storage of telecom-C-band heralded single photons with orbital-angular-momentum encoding in a crystal.

A memory-based quantum repeater architecture provides a solution to distribute quantum information to an arbitrary long distance. Practical quantum repeaters are likely to be built in optical-fiber networks which take advantage of the low-loss transmission between quantum memory nodes. Most quantum memory platforms have characteristic atomic transitions away from the telecommunication band.

[Effects of inner-heating acupuncture on apoptosis of chondrocytes and expression of Caspase-3 and Caspase-9 in rats with knee osteoarthritis].

Objective: To investigate the effect of inner-heating acupuncture on apoptosis of chondrocytes and expression of Caspase-3 and Caspase-9 in rats with knee osteoarthritis (KOA).

Methods: A total of 32 rats were divided into a normal group, a model group, a control treatment group and a treatment group by random number grouping method, 8 rats in each one. The rats in the normal group received no intervention.

Multiplexed storage and real-time manipulation based on a multiple degree-of-freedom quantum memory.

The faithful storage and coherent manipulation of quantum states with matter-systems would enable the realization of large-scale quantum networks based on quantum repeaters. To achieve useful communication rates, highly multimode quantum memories are required to construct a multiplexed quantum repeater. Here, we present a demonstration of on-demand storage of orbital-angular-momentum states with weak coherent pulses at the single-photon-level in a rare-earth-ion-doped crystal.
