Machine learning the arrow of time in solid-state spins
Xiang-Qian Meng, Zhide Lu, Ya-Nan Lu +9
Understanding the emergence of the thermodynamic arrow of time in microscopic systems is of fundamental importance, particularly given that unitary evolution preserves time-reversa…
Dynamical freezing and enhanced magnetometry in an interacting spin ensemble
Ya-Nan Lu, Dong Yuan, Yixuan Ma +10
Understanding and controlling non-equilibrium dynamics in quantum many-body systems is a fundamental challenge in modern physics, with profound implications for advancing quantum t…
Observation of quantum superposition of topological defects in a trapped ion quantum simulator
Zhijie Cheng, Yukai Wu, Shijiao Li +8
Topological defects are discontinuities of a system protected by global properties, with wide applications in mathematics and physics. While previous experimental studies mostly fo…
Hybrid entanglement and error correction in a scalable quantum network node
Xiu-Ying Chang, Pan-Yu Hou, Wen-Gang Zhang +7
Recent breakthroughs have ushered the quantum network into a new era, where quantum information can be stored, transferred, and processed across multiple nodes on a metropolitan sc…
Hamiltonian learning for 300 trapped ion qubits with long-range couplings
S. -A. Guo, Y. -K. Wu, J. Ye +12
Quantum simulators with hundreds of qubits and engineerable Hamiltonians have the potential to explore quantum many-body models that are intractable for classical computers. Howeve…
