advantages of quantum computer
compared with classical computer, the most prominent advantage of quantum computer is its powerful computing power, but at present, there are only about 50 quantum computers available in the world. If it can not be used effectively, there will be a waste of computing power. Therefore, the quantum computer also needs the operating system to deploy and manage it effectively, and the coordinated development of hardware and software can make the quantum computer realize the landing application
with the advent of the era of quantum computing, "Benyuan Sinan" can not only make quantum computers run more efficiently, but also cultivate users' habit of using domestic quantum operating system, so that Chinese people can master the real core technology in the era of quantum computing

4. Single photon source is the core resource of optical quantum information technology. Recently, pan Jianwei, academician of the Chinese Academy of Sciences and professor of the University of science and technology of China, led by Lu Chaoyang and Huo Yongheng, and cooperated with a number of domestic, German and Danish scholars to put forward a new theoretical scheme for the first time in the world, successfully realizing a single photon source with definite polarization, high purity, high homogeneity and high efficiency in narrow-band and broadband microcavity, It lays an important scientific foundation for optical quantum computer to surpass classical computer. Recently, nature photonics, an international authoritative academic journal, published this achievement, evaluating that it has "solved a long-standing challenge"
in February this year, the relevant person in charge of the Ministry of science and technology said at the press conference of the state information office that China's new science and technology planning system will focus on supporting the future basic research in quantum communication and other aspects. According to market analysis, China is in the leading position in the research and instrial application of quantum communication technology. Once more technological breakthroughs are achieved in the future, its market space will be very broad
5. In the case of interdisciplinary application, because science and engineering need strong basic knowledge, many students will choose interdisciplinary business majors. The following is a preliminary arrangement of the requirements of undergraate background for several majors for reference. 1. Accounting applications in the United States are divided into three types: with accounting background, without accounting background but with other business background, and without business background at all. It can be seen from this that accounting is not a major with high requirements for professional background. However, as there are many opportunities for accountants to engage in internships, we usually help clients find some highlights in their previous internships and take them out as an important part of their resumes. 2. MBA major (MBA major application) MBA attaches great importance to work experience. In particular, the MBA of the better ranked business school not only has requirements for working years, but also has certain requirements for the position and the scale of the enterprise. If you have more than five years of executive experience in Global 500 companies, top business schools such as (HBS) Harvard University, (Wharton) University of Pennsylvania, (Stern) New York University are the dreamschool you can apply for. In the preparation of materials, we should emphasize that we have the decision-making power for the company's strategy, finance, personnel and other aspects. The work like PM of software company is not considered as the same as "management work". For MBA, work experience is a must, especially leadership, which is more important than academic achievement. 3. Financial related majors (financial application) rarely mention the requirements of work experience in the admission of financial majors. But the current financial professional is too popular, inexperienced applicants are in an absolute disadvantage in the application. So much so that the "71" (GMAT & gt; 700，IBT> It's hard to target the top 80 MSF in the United States MSF has about 30 schools in the top 100 in the United States. In this context, people choose to work first and then apply. As a result, a large number of applicants with working experience in investment banking or corporate finance have emerged. As a result, the admission requirements further rise. With our years of experience, undergraates can actively participate in internships in banks and other places ring their schooling. For example, Huaqi bank, Everbright Bank, Bank of East Asia and Standard Chartered Bank also provide professional internship opportunities for students studying abroad in New Oriental, which provides another way for some students who lack financial work experience. Finance is one of the majors that pay more attention to work experience. If you are not a student majoring in finance, the internship and work experience related to the financial field will become the weight of the application. 4. HR human resource management related human resource management majors do not have too many requirements for the applicant's work experience, because HR emphasizes the understanding of some relevant laws and regulations and the mastery of recruitment and other links. These contents can be better mastered through classroom teaching. However, if you are an experienced HR manager, you will have a greater advantage in the application. If you have worked as a human resource supervisor in the company and have a deep understanding of recruitment, personnel, assessment, etc., you can highlight it in the application documents. 5. Marketing related majors: in fact, the marketing related majors in the United States are different from those in China. American universities pay more attention to the relevant experience of applicants. Experienced marketing personnel can easily obtain relevant nutrition from various case studies and improve their own level. Marketing focuses on the cultivation of advanced ways of thinking, including diversified perspectives, targeted judgments and broad international vision. With heavy schoolwork and numerous practical cases, it is the best example to train students to think and observe independently, make clear judgments and effectively express, and even implement. Generally speaking, working experience is not a necessary condition to apply for marketing, but it is absolutely an essential factor to improve one's background. If you are a new graate, lack of work experience, internship and vacation internship work experience is particularly important, in order to make up for the lack, will receive significant results. 6. Logistics chain management related (logistics professional application) the professional requirements for experience belong to a relatively common category. Experienced consultants know that the requirements of logistics chain management for mathematics and statistics are higher than those of other business majors. Moreover, some Logistics Majors in American universities focus on management and work experience in business schools, some have independent logistics majors or supply chain majors, and some have instrial engineering majors, Emphasis on budget management analysis, suitable for science and engineering students. The requirement for work experience is not as high as that of other business majors, except for logistics management under indivial MBA. But we must remind the applicant that experience is not a must. Generally speaking, it refers to the undergraate students majoring in this major. If the major of undergraate study is not related to this, then some experience represents a certain basic understanding, which is still necessary. 7. Sports Management / real estate management / hotel management: this kind of specialty belongs to the management of special field. In teaching, this kind of management course involves a lot of knowledge and skills related to the exclusive field. Therefore, having relevant experience is of great help to learning. However, it is precisely because of the specificity of such fields that knowledge accumulation can be achieved to a large extent by means of books and classroom teaching. If combined with this, some internships will have a great effect. It is not like abstract management. If there is no certain practical experience in advance, it will feel like a castle in the air.
