Yes.But it was reported in Chinese. http://news.ustc.edu.cn/?article=00023439&

Recently ,it is reported that University of science and technology of China and Tsinghua University together have succeeded in conducting quantum teleportation between the distance of 16km.Are quantum information prospectinve? And how long it will be applied as commonly as the present one ...

I have read some books about quantum physics.There are about too kinds of interpretation about uncertainty relationship.The first is that it consists in single measurement.However the other one is statistical explanation that it just consists in measuring repeatedly.I support the former...

Yes,The equation is just the eigenvalue equation of Lx. As you say ,the another approach is" consider how the spherical harmonics transform under rotations. ".But in my opinion,it is not so easy to do as you expected.

The system is at the state of Φ=aY_11+bY_20 (a^2+b^2=1),please find the possible eigenfunctions of Lx and the relevant possibilities? My solution: I have attempted to use the matrix mechanics to work out the exercise,but I should work out a 8-order matrix. Firstly I use the Fmn=〈m︳F|n〉to...

I now is studying the Applied physics in a university of technology in China,which is not the best university in China ,just rank about the 30th .In our school there is little famous physicist and the lab equipments are so poor.we just study the books.I dare say,we study just for passing the...

I am poor in mathematics .Can I study applied physics well?And what should I do first?

Hello!I`m a Chinese.Our country has been rapidly developing,but it has a long distance behind from US or UK,especially in eduacation system and concept .I am majoring inapplied physics in NEU China,but physics are not so emphasized as the others.Many people and some governments only highly...

It is so difficult to answer

Why can I not contact the website in China?
