Quantum computation utilizes unique resources such as quantum superposition and quantum entanglement to encode and process information and has been proved to be dominantly advantageous over classical computation on certain important scientific and engineering problems. Potential applications of quantum computation are expected to influence future information technology and many other related fields deeply and significantly. In this article, we briefly review the history of quantum computation, including how its fundamental ideas and concepts came into being and the development of its significant theories and algorithms. We also discuss the status and outlook of several representative technical routes in this field, including superconducting quantum computation, distributed superconducting quantum computation, photonic quantum computation, trapped-ion quantum computation, silicon-based quantum computation, as well as other systems. Furthermore, by analyzing certain common issues faced by all routes, we propose some thoughts and suggestions for future development of quantum computation in China. We particularly emphasize the following: reinforcement of strategic planning at a national level, establishment of a research team of high caliber, and boost of relevant fundamental research and development of core techniques and critical instruments.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67371360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the development requirement for water security in the Haihe River Basin, we analyzed the problems regarding water security assurance from the perspectives of water resources, water environment, water ecology, and flood disasters. Subsequently, we predicted the development trend of water security in the Haihe River Basin by 2035 through data simulation. On this basis, an overall idea was proposed, that is, assuring water security in the Haihe River Basin by reinforcing measures for protecting water ecology, and highlighting the role of water resources carrying capacity. Focus should be placed on developing capacities regarding (1) systematic allocation and efficient utilization of water resources, (2) comprehensive improvement in water environment, (3) governance and restoration of basin ecology, and (4) prevention and emergency response of flood disasters. Furthermore, we proposed the following suggestions from a technological perspective: (1) implementing new strategies for the conservation and efficient utilization of water resources, (2) ensuring drinking water safety and improving water governance capacities, (3) establishing a water ecological pattern that features people-water harmony, and (4) developing a flood disaster prediction and response mechanism.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67371833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For future development, it is necessary to analyze the water security risks and propose targeted countermeasures, thus to ensure the coordinated development of the Beijing‒Tianjin‒Hebei region and build this region into a world-class urban agglomeration. In this study, we summarize the key national policies, socio-economic development trends, and ecological protection requirements of the region. In addition, we analyze the water security status and relevant major scientific issues. Our findings are as follows. (1) The contradiction between supply and demand of water resources is the primary problem that threatens water security in the Beijing‒Tianjin‒Hebei region, and water resources in the region will probably continue to decay by 1‒2 billion m. Therefore, to guarantee the security of the regional water system, 3.9‒6 billion m of water needs to be transferred into this region via the South-to收稿日期:2021-11-29;修回日期:2021-12-30 通讯作者:王庆明,中国水利水电科学研究院水资源研究所高级工程师,研究方向为水文水资源;E-mail:wangqm@iwhr.com 资助项目:中国工程院咨询项目“面向2050年京津冀水安全挑战与应对战略”(2021-XY-06);国家杰出青年科学基金(52025093) 本刊网址:www.engineering.org.cn/ch/journal/sscae","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67373845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study first investigates the current status and trend of China ’ s new energy development and then prospects grid integration scenarios for a high proportion of new energies in China in the medium (2030) and long term (2060). The challenges faced by the grid integration are analyzed, including coexistence of high-efficiency consumption and energy guarantee problems, increasing difficulty in safe and stable operation, and an unsuitable power market mechanism. Moreover, a key technology system is proposed from the perspectives of source side, grid side, load side, as well as energy storage and basic support. To achieve long-term steady development of the gird integration and operation for the high-proportioned new energy, we propose to strengthen coordinated planning to promote flexibility, make breakthroughs in key technologies, establish an interim mechanism between new energy policies and the power market, and improve the design of the power market to adapt to new energy consumption scenarios. This study could provide a basic reference for the research on power system planning and electric technologies.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67374288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
