When I met the difficulties in the statistical analysis of the doctoral thesis questionnaire, I couldn't find a clue. Finally, I saw Dr.Tong's assistance in the statistical analysis of the thesis questionnaire on qimo.com. With the assistance of the doctor, I got the results smoothly. Thank Dr.Tong for his assistance in the statistical analysis of the thesis questionnaire, which solved my urgent problem.

Previously, a local statistics company in Hong Kong was entrusted, but it failed to do a good job in medical statistics. In my anxiety, I saw the doctor teacher of Dr.Tong statistics company provide statistical running and guidance, and sent the data and requirements to the doctor teacher. With the efforts of the doctor teacher, the analysis results were successfully made. I feel that Taiwan's statistics companies are more professional and the fees are reasonable.

When I met the difficulties in the statistical analysis of the pre-test and post-test of the thesis questionnaire, I couldn't solve them all the time. On Qimo, I saw that the doctoral teacher of Dr.Tong statistics company provided the tutoring service of thesis statistics, and sent the information and requirements to the doctoral teacher. With the help and guidance of the teacher, I got the results. Thank you very much for the tutoring service of the doctoral teacher of Dr.Tong statistics company There are two difficulties.

It's difficult to analyze Stata data in accounting papers. On Yahoo Qimo, I saw the doctor teacher of Dr.Tong statistics company provide Stata statistical running guidance. The data and requirements were sent to the doctor's teacher. Under the guidance of the doctor's teacher, the Stata code was successfully designed, and the analysis results were also run out. I would like to thank the doctor's teacher of Dr.Tong statistics for his high level guidance and assistance.

Educational papers have quantitative statistics, which is a bit difficult! Helpless, I saw on Yahoo Qimo that Dr. and postdoctoral teachers from Dr.Tong Statistics Company provide doctoral thesis statistics and counseling services. I sent the questionnaire and sample data to the doctor, and with the guidance and assistance of the doctor, I successfully obtained the results and graduated. I am very grateful for the professional guidance of the doctor and postdoctoral teacher from Dr.Tong Statistics Company. The technical expertise, reliable quality, and reasonable fees have saved me a lot of trouble.

The reporter learned from the University of science and technology of China on the 10th that Guo Guoping and Cao Gang, the academician team of Guo guangcan of the University, cooperated with Benyuan quantum computing Co., Ltd. to measure the excitation energy spectrum of semiconductor double quantum dots by using a microwave superconducting resonator. The related research results were published in the international well-known Journal of Applied Physics "review of Applied Physics".
Semiconductor system is considered to be one of the most promising systems to realize universal quantum computing due to its good scalability and integration. In recent years, silicon-based semiconductor quantum computing has made a series of progress, quantum bit performance has been greatly improved, and the fidelity of single bit and two bit logic gates have reached the threshold of fault-tolerant quantum computing. How to further expand the number of bits and improve the bit reading fidelity has become an important topic in this field.
Using microwave photons as the medium, circuit quantum electrodynamics can be used not only to realize long-range coupling between bits, but also to detect bits non destructively and sensitively. Researchers have prepared niobium titanium nitride microwave resonant cavity semiconductor quantum dot composite devices. Using the high impedance characteristics of niobium titanium nitride, the coupling strength between microwave resonant cavity and qubit is greatly improved, reaching the strong coupling range. Furthermore, a square wave pulse is applied to the device to drive the electron transition between different energy levels of the quantum dot, and the transition signal is read out by using a highly sensitive microwave resonator. Using this technique, the energy level spectrum of the double quantum dot system is represented, especially the information of the spin state occupation of the system is given by using the response characteristics of the signal to different energy levels.
The results provide an effective method for high fidelity readout of semiconductor qubits in the future.
