Single-Shot Readout of a Nuclear Spin Weakly Coupled to a Nitrogen-Vacancy Center
Gang-Qin Liu, Jian Xing, Wen-Long Ma +5
Single-shot readout of qubits is required for scalable quantum computing. Nuclear spins are superb quantum memories due to their long coherence times but are difficult to be read o…
Effect of bath temperature on the decoherence of quantum dissipative systems
Wei Wu, Hai-Qing Lin
We report an anomalous decoherence phenomenon of a quantum dissipative system in the framework of a stochastic decoupling scheme along with a hierarchical equations-of-motion forma…
Maximal coherence in generic basis
Yao Yao, G. H. Dong, Li Ge +2
Since quantum coherence is an undoubted characteristic trait of quantum physics, the quantification and application of quantum coherence has been one of the long-standing central t…
Nonadiabatic holonomic quantum computation with dressed-state qubits
Zheng-Yuan Xue, Feng-Lei Gu, Zhuo-Ping Hong +4
Implementing holonomic quantum computation is a challenging task as it requires complicated interaction among multilevel systems. Here we propose to implement nonadiabatic holonomi…
Fisher information of a squeezed-state interferometer with a finite photon-number resolution
P. Liu, P. Wang, W. Yang +2
Squeezed-state interferometry plays an important role in quantum-enhanced optical phase estimation, as it allows the estimation precision to be improved up to the Heisenberg limit…

We study the spontaneous decoherence of the coupled harmonic oscillators confined in a ring container, where the nearest-neighbor harmonic potentials are taken into consideration.…
Quantifying Spontaneously Symmetry Breaking of Quantum Many-body Systems
G. H. Dong, Y. N. Fang, C. P. Sun
Spontaneous symmetry breaking is related to the appearance of emergent phenomena, while a non-vanishing order parameter has been viewed as the sign of turning into such symmetry br…
Spin-Orbit Coupling Induced Spin Squeezing in Three-Component Bose Gases
X. Y. Huang, F. X. Sun, W. Zhang +2
We observe spin squeezing in three-component Bose gases where all three hyperfine states are coupled by synthetic spin-orbit coupling. This phenomenon is a direct consequence of sp…

Da-Wei Luo, Jing-Bo Xu
We use an alternative method to investigate the quantum criticality at zero and finite temperature using trace distance along with the density matrix renormalization group. It is s…
Magnon Kerr effect in a strongly coupled cavity-magnon system
Yi-Pu Wang, Guo-Qiang Zhang, Dengke Zhang +6
We experimentally demonstrate magnon Kerr effect in a cavity-magnon system, where magnons in a small yttrium iron garnet (YIG) sphere are strongly but dispersively coupled to the p…
