Rotation of polarization of a multiphoton state
TL;DR: In this article, a single polarized photon can be rotated to its orthogonally polarized state with an angle of π / 2 for the state of N polarized photons in the same spatial mode, the rotation angle can vary between π 2 N and π − π/2 N for different states.

Shuang Wang,Wei Chen,Zhen-Qiang Yin,De-Yong He,Hong-Wei Li,Zheng Zhou,Zheng-Fu Han,Guang-Can Guo +7 more
TL;DR: In this article, a high-speed low-voltage phase modulation method applied to an external ring modulation quantum key distribution system is described, where two optical pulses pass through a phase modulator before and after a period.
Journal ArticleDOI

Jian-Shun Tang,Yi-Tao Wang,Geng Chen,Yang Zou,Chuan-Feng Li,Guang-Can Guo,Ying Yu,Mi-Feng Li,Guo-Wei Zha,Haiqiao Ni,Zhi-Chuan Niu,Manuel Gessner,Heinz-Peter Breuer +12 more
TL;DR: In this article, an all-optical experimental detection and quantification of quantum correlations between the polarization and the frequency degrees of freedom of single photons by means of local operations acting only on the polarization degree of freedom is presented.
Journal ArticleDOI
Twin-field quantum key distribution with passive-decoy state.
Jun Teng,Feng-Yu Lu,Zhen-Qiang Yin,Guan-Jie Fan-Yuan,Rong Wang,Shuang Wang,Wei Chen,Wei Huang,Bing-Jie Xu,Guang-Can Guo,Zheng-Fu Han +10 more
TL;DR: To enhance the source security of TF-QKD, in this article, the authors proposed a passive-decoy based protocol, in which they combine TFQD with the passive decoy method, and they presented a simulation comparing the key generation rate with that in active decoy.
Journal ArticleDOI
Strong indirect coupling between graphene-based mechanical resonators via a phonon cavity
Gang Luo,Zhuo-Zhi Zhang,Guang-Wei Deng,Hai-Ou Li,Gang Cao,Ming Xiao,Guang-Can Guo,Lin Tian,Guo-Ping Guo +8 more
TL;DR: In this article, the experimental observation of strong indirect coupling between separated mechanical resonators in a graphene-based electromechanical system is reported. But the results may lead to the development of gate-controlled all-mechanical devices and open up the possibility of long-distance quantum mechanical experiments.
