Retrospection

During my one-month stay in MIT, I learned quite a few things and made quite a few friends. My topic of research was: calculation of bell’s inequality and experimental requirements under certain noise conditions.

在MIT学习了1个月,我学到了不少东西,交了不少朋友。我的研究课题是:calculation of bell’s inequality and experimental requirements under certain noise conditions.

On my day one, Prof. F took me around the campus and let me get acquainted with the whereabouts. F is the general manager of the research program and taught us systematic ways of doing research with a database. The first few lectures were given by Chris, who reviewed the basic concepts of quantum mechanics and introduced the topic of non-linear optics. We met with professor Z, who is an expert in non-linear optics, photon detection, single photon generation, information theory and, most importantly, Quantum Key Distribution. He gave us lectures regarding how to solve Schrodinger equations corresponding to entangled photons pairs.Chris also taught me some matlab.

在我的第一天,F老师带我参观了校园,让我了解了麻省理工的校园各个实验室、教学楼的分布情况。F老师是麻省理工科研的教学主任,教我们用数据库进行研究的系统方法。前几堂课是由Chris主持的。回顾了量子力学的基本概念,介绍了非线性光学的基本概念。我们会见了Z教授,他是一个在非线性光学、光子探测、单光子产生、信息理论和最重要的量子密钥方面的专家分布。他给我们讲了如何解决纠缠光子对的薛定谔方程。Chris还教了我一些MATLAB。

In the second week, Chris taught us concepts regarding squeezed states and Bell’s inequality. He assigned an 70-page-paper and a few other papers to read so that we can grasp the gist of bell’s inequality. I asked considerable amount of questions during the classes and other meetings and extensively broadened my knowledge about basic quantum mechanics. Professor Z gave us reviews about his on-going research about quantum key distribution, which can ensure quantum communication hundreds of times faster than the older protocol. Chris also gave us a lab tour and taught us about the technologies being employed to make the QKD experiments possible.

在第二周,Chris讲述了压缩为克里斯和贝尔不等式。他给一个70页的纸和一些其他的论文,我们可以读到这样的掌握要点贝尔不等式。我问的问题在considerable类和数量我会和其他extensively关于量子力学的基本知识的扩展。Z教授给他在美国的评论我们要研究网络,量子密钥分配,量子通信可以确保更快的之前更好。Chris也给我们实验室参观和我们有关的人、技术为主,使可能的量子密钥分发实验。

The research about Bell’s inequality starts in week three and we start doing computations of the bell’s inequality. We were introduced to professor U from Academy of Science. Professor U gave us lectures on the current imaging technologies and his own on-going research about the imaging with photon scanners and imaging processing techniques using spacial and time correlation to yield high-resolution images, which works well even under single pixel conditions.

贝尔不等式的研究始于第三周,我们开始计算贝尔不等式。我们介绍了科学院U教授。U教授给我们讲授了目前的成像技术和他自己的技术—利用光子扫描仪成像和利用空间和时间相关进行成像处理的研究高分辨率图像,即使在单像素条件下也能很好地工作。

In the last week, we did the computations of bell’s inequality under low detection efficiencies and possibilities of dark count. The equation typing was painful and the results weren’t quite pleasant since I yielded a result above three while the S value is impossible to surpass 2*2^0.5. Apart from that, research scientist D gave us really informative lectures on Fourier optics, solving optical problems with maxwell equations and a lot of new ways of solving for wave propagation. The e^ikx system was especially intriguing. At the last day, research scientist F bought us dinner.

最后一个星期,我们计算了低探测效率下的贝尔不等式和暗计数的可能性。这个方程分型是痛苦的,结果不太令人满意,因为我得出的结果超过三,而S值是不可能的。超过2×2×0.5。除此之外,研究科学家D给我们提供了关于傅立叶光学的非常翔实的讲座,解决光学问题。用麦斯威尔方程组和许多新的波传播求解方法。E ^ ikx系统是特别有趣。在最后一天,研究科学家F给我们买了晚餐,我们一起共进晚餐。

Throughout the program, F gave us lectures on how to use endnote to search for and organize papers. He informed us how to cite correctly and maneuver the correlations between google scholar, SCI, word and endnote to work more efficiently and accurately. These are all important research skills. Moreover, I was able to build up a small base of possibly needed papers using MIT free access of all papers, which was quite useful. We were also able to hear some lectures given by the librarian, who is also a biologist at MIT, on the topics of efficient file managing and using LATEX as well as efficiently using MIT online library.

在整个科研过程中,F给我们讲如何使用尾注来搜索和整理文件。他告诉我们如何引用。正确操纵谷歌的学者,SCI的相关性,字和尾注工作更高效和准确。这些都是所有重要的研究技能。此外,我还可以利用麻省理工学院所有论文的免费访问,建立一个可能需要的论文的小基地,这很有用。我们也能听到图书管理员的一些讲座,他也是麻省理工学院的生物学家。有效的文件管理和使用胶乳,并有效地使用麻省理工学院在线图书馆。

We have food across the Mass Ave in the Student center. The food provided at the home stay was much more pleasant in contrast. My sole classmate YC was a good teacher to me as well. He is going to be a senior in NYU and he told me quite a lot about how things, especially research, works in the university, which greatly improves my sophistication of college life planning. He helped me a lot with the studies and answered a lot of my academic questions since he has all the college education I don’t have.

我们在MIT的学生中心上吃午餐。寄宿家庭提供的食物更令人愉快。我唯一的同学YC是一个好的老师对我好。他将是纽约大学的一名大四学生,他告诉了我很多事情,特别是研究,在大学工作,大大提高了我的大学生活规划的复杂性。他在学习上给了我很多帮助。回答了很多我的学术问题,因为他有我所没有的大学教育。

In general, this research program taught me a lot about academics and life. It tells me how research looks like and that they don’t always go in the way you want them to go. It gives me a lot of informations regarding how to become a successful academic, and later, a professor. The ways relations work in academia was also informative and I hope I have made some personal connections that would be useful in my future career.

总的来说,这个研究项目教会了我很多关于学术和生活的知识。它告诉我研究是怎样的,而且并不总是如此。走在路上你想让他们走。它给了我很多关于如何成为一个成功的学者和教授。在学术界工作关系的方式也很有意义,我希望我有一些个人关系,对我未来的事业有用。
