  • The development of active optical clock

    Jia Zhang, Tiantian Shi, Jianxiang Miao & Jingbiao Chen

    Abstract The atomic clocks, whether operating at optical or microwave region, can be divided into two categories according to their working mode, namely the passive clocks and active clocks. The passive clocks, whose standard frequency is locked to an ultra-narrow atomic spectral line, such as laser cooled Cs beam or lattice trapped Sr atoms, depend on the spontaneous emission line. On the contrary, the active clocks, in which the atoms are used as the gain medium, are based on the stimulated e

    Jiansheng Hu, Weibin Xi, Jian Zhang, Liansheng Huang, Damao Yao, Qing Zang, Yanlan Hu, Guizhong Zuo, Qiping Yuan, Jinping Qian, Zhiwei Zhou, Xinjun Zhang, Mao Wang, Handong Xu, Yahong Xie, Zhengchu Wang, Haiqing Liu, Youwen Sun, Liang Wang, Guoqiang Li, Hongxing Yin, Yao Yang, Xianzu Gong, Kun Lu, Guosheng Xu, Junling Chen, Fukun Liu, Jiangang Li, Yuntao Song & the EAST team

    Abstract Experimental Advanced Superconducting Tokamak (EAST) was built to demonstrate high-power, long-pulse operations under fusion-relevant conditions, with major radius R = 1.9 m, minor radius a = 0.5 m, and design pulse length up to 1000s. It has an ITER-like D-shaped cross-section with two symmetric divertors at the top and bottom, accommodating both single null and double null divertor configurations. EAST construction was started in 2000, and its first plasma was successfully obtained i

  • Recent progress on coherent computation based on quantum squeezing

    Bo Lu, Lu Liu, Jun-Yang Song, Kai Wen & Chuan Wang

    Abstract Squeezed vacuum state of light is an important concept of quantum optics which has an uncertainty reduction in a specific quadrature compared to the coherent vacuum state. The coherent Ising machines (CIMs) based on the squeezed state are capable of searching the ground state of the Ising model, which can be used to solve combinatorial optimization problems and have been experimentally demonstrated to have excellent computational performance. This review introduces the recent progress
