Investigation of the Effect of Quantum Measurement on Parity-Time Symmetry
Wei-Chen Wang, Yi Xie, Man-Chao Zhang +6
Symmetry, including the parity-time ()-symmetry, is a striking topic, widely discussed and employed in many fields. It is well-known that quantum measurement can dest…
Observation of -symmetric quantum coherence in a single ion system
Wei-Chen Wang, Yan-Li Zhou, Hui-Lai Zhang +9
Parity-time()-symmetric systems, featuring real eigenvalues despite its non-Hermitian nature, have been widely utilized to achieve exotic functionalities in the class…
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…
Intrinsic basis-independent quantum coherence measure
Wei-Chen Wang, Mao-Fa Fang, Min Yu
Quantum coherence is a key resource in quantum information processing scenarios, and quantifying coherence is an important task for both quantum foundation and quantum technology.…
Protecting coherence in the non-Hermitian two-level system
Wei-Chen Wang, Mao-Fa Fang
We have constructed a non-Hermitian two-level system (a PT -symmetric system) in dissipative environments, and investigated the quantum coherence in the non-Hermitian two-level sys…
