Observation of Non-Gaussian Magnon Dynamics in a Two-Dimensional Long-Range XY Model
S. -A. Guo, J. -Y. Tan, J. Ye +11
Non-Gaussian evolution of high-order spin correlations characterizes important properties of quantum many-body systems. In practice, decoherence, statistical fluctuation and miscal…
Quantum simulation of thermalization dynamics of a nonuniform Dicke model
S. -A. Guo, J. Ye, J. -Y. Tan +11
Previous experimental realizations of Dicke model in atomic or ionic systems are based on global observables assuming uniform spin-boson coupling, while inevitable experimental non…
Long-time storage of entangled logical states in decoherence-free subspaces
L. Zhang, Y. -L. Xu, Y. -K. Wu +11
The maintenance of quantum entanglement lays the elementary building block of quantum information processing, requiring an integration of long coherence time, sufficient storage ca…
Hardware-Economic Manipulation of Dual-Type Yb Qubits
Y. -J. Yi, Y. -Y. Chen, Y. -H. Hou +10
The dual-type qubit scheme is an emerging method to suppress crosstalk errors in scalable trapped-ion quantum computation and quantum network. Here we report a hardware-economic wa…
Stretched Exponential Scaling of Parity-Restricted Energy Gaps in a Random Transverse-Field Ising Model
G. -X. Tang, J. -Z. Zhuang, L. -M. Duan +1
The success of a quantum annealing algorithm requires a polynomial scaling of the energy gap. Recently it was shown that a two-dimensional transverse-field Ising model on a square…
A metropolitan-scale trapped-ion quantum network node with hybrid multiplexing enhancements
Z. -B. Cui, Z. -Q. Wang, P. -C. Lai +13
Quantum network and quantum repeater are promising ways to scale up a quantum information system to enable various applications with unprecedented performance. As a current bottlen…
