Estimation of the Laser Frequency Nosie Spectrum by Continuous Dynamical Decoupling
Manchao Zhang, Yi Xie, Jie Zhang +5
Decoherence induced by the laser frequency noise is one of the most important obstacles in the quantum information processing. In order to suppress this decoherence, the noise powe…

Weak-to-strong transition of quantum measurement in a trapped-ion system
Yiming Pan, Jie Zhang, Eliahu Cohen +3
Quantum measurement remains a puzzle through its stormy history from the birth of quantum mechanics to state-of-the-art quantum technologies. Two complementary measurement schemes…

Scheme and Experimental Demonstration of Fully Atomic Weak Value Amplification
Chun-wang Wu, Jie Zhang, Yi Xie +4
In this paper, we explore the possibilities of realizing weak value amplification (WVA) using purely atomic degrees of freedom. Our scheme identifies the internal electronic states…
