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…
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…
Long-time storage of a decoherence-free subspace logical qubit in a dual-type quantum memory
Y. L. Xu, L. Zhang, C. Zhang +14
A quantum memory is an essential element for quantum computation, quantum network and quantum metrology. Previously, a single-qubit quantum memory with a coherence time of about an…
Quantum tomography of a third-order exceptional point in a dissipative trapped ion
Y. -Y. Chen, K. Li, L. Zhang +9
The requirement for Hermiticity in quantum mechanics ensures the reality of energies, while the parity-time symmetry offers an alternative route to achieve this goal. Interestingly…
Programmable Quantum Simulations of Spin Systems with Trapped Ions
C. Monroe, W. C. Campbell, L. -M. Duan +10
Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting quantum spin models. Effective spins are represented by appropriate internal energy le…
