Article Synopsis
- Photon-based entanglement sources, essential for creating entangled states, often suffer from quality loss due to birefringence in nonlinear crystals during spontaneous parametric down-conversion.
- The study provides a theoretical analysis of birefringent walk-off and demonstrates that using pre- and post-compensation can improve entangled photon quality.
- Experimental validation shows significant success, achieving a violation of CHSH-Bell's inequality by about 366 standard deviations, making this method applicable to various optical quantum technologies, such as computation, sensing, and communication.
Objective: To investigate the effects of postoperative femoral neck shortening in patients with femoral neck fractures fixed with femoral neck system screws (FNS) and to explore the factors influencing femoral neck shortening.
Method: To retrospectively analyze the data of 113 patients with femoral neck fractures admitted to the Second Hospital of Fuzhou City, affiliated with Xiamen University, between December 2019 and January 2022. Of these, 87 patients were followed up for more than 12 months, 49 men and 38 women: 36 cases of Garden I and II fractures and 51 cases of Garden III and IV fractures, to record the patient's hip Harris score at 12 months postoperatively.
