Quantum information science is a new interdisciplinary subject,which has unique performance in the field of information.It can break through the limits of the existing classical information systems in the aspects of improving computing speed,ensuring information security,increasing information capacity and improving detection accuracy.Grover algorithm is a typical quantum algorithm,which can realize quadratic acceleration for any classical brute force exhaustive search problem,further promoting the development of quantum computing.How to effectively improve and apply Grover algorithm has become an important research field of quantum computing.This paper summarizes the optimization,improvement and application of Grover algorithm,summarizes the application and improvement of Grover algorithm in different fields,and discusses some research directions of future algorithm improvement and related applications of Grover algorithm.

Objective: To explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation., Methods: One hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups., Results: The PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05)., Conclusion: Warm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.

Objective: To explore the therapeutic effect of acupuncture combined with medication on continuing unovulation infertility., Methods: Fifty cases of continuing unovulation infertility were randomly divided into an observation group and a control group, 25 cases in each group. The observation group was treated with Chinese herbal decoction plus acupuncture. Culuanpao decoction, Cupailuan decoction and Cuhuangti decoction were respectively given according to different menstrual cycles and acupuncture and moxibustion at Guanyuan (CV 4), Zhongji (CV 3), Luanchao (ovary), etc. The control group was treated with oral administration of Clomiphene and intramuscular injection of Chorionic Gonadotropin. They were treated for 6 cycles and the ovulation rate and the pregnancy rate were observed., Results: There was no significant difference in the ovulation rate between the two groups (P > 0.05). The pregnancy rate of 44.0% in the observation group was significantly higher than 16.0% in the control group (P < 0.05). The observation group was superior to the control group in the score of mucus and the endometrial thickness., Conclusion: Both acupuncture combined with medication and oral administration of clomiphene plus intramuscular injection of chorionic gonadotropin have higher ovulation rate, and the former was higher than the latter in the pregnancy rate.
