Improving the Precision of Optical Metrology by Detecting Fewer Photons
Peng Yin, Wen-Hao Zhang, Liang Xu +13
In optical metrological protocols to measure physical quantities, it is, in principle, always beneficial to increase photon number to improve measurement precision. However, practi…
One-hour coherent optical storage in an atomic frequency comb memory
Yu Ma, You-Zhi Ma, Zong-Quan Zhou +2
Photon loss in optical fibers prevents long-distance distribution of quantum information on the ground. Quantum repeater is proposed to overcome this problem, but the communication…
Hyperfine interaction and coherence time of praseodymium ions at the site 2 in yttrium orthosilicate
Yi-Xin Xiao, Zong-Quan Zhou, Yu Ma +4
Praseodymium (Pr) ions doped in the site 1 of yttrium orthosilicate (YSiO) has been widely employed as the photonic quantum memory due to their excellent optical coh…
Reliable coherent optical memory based on a laser-written waveguide
Chao Liu, Zong-Quan Zhou, Tian-Xiang Zhu +10
-doped yttrium silicate ( ) crystal is a unique material that possesses hyperfine states with coherence time up to 6 h. M…
Strict experimental test of macroscopic realism in a light-matter-interfaced system
Xiao Liu, Zong-Quan Zhou, Yong-Jian Han +10
Macroscopic realism is a classical worldview that a macroscopic system is always determinately in one of the two or more macroscopically distinguishable states available to it, and…
Hyperfine Structure and Coherent Dynamics of Rare Earth Spins Explored with Electron-Nuclear Double Resonance at Sub-Kelvin Temperatures
Pei-Yun Li, Chao Liu, Zong-Quan Zhou +12
An experimental platform of ultralow-temperature pulsed ENDOR (electron-nuclear double resonance) spectroscopy is constructed for the bulk materials. Coherent property of the coupl…
