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…
Individually Addressed Entangling Gates in a Two-Dimensional Ion Crystal
Y. -H. Hou, Y. -J. Yi, Y. -K. Wu +14
Two-dimensional (2D) ion crystals have become a promising way to scale up qubit numbers for ion trap quantum information processing. However, to realize universal quantum computing…
A Site-Resolved 2D Quantum Simulator with Hundreds of Trapped Ions
S. -A. Guo, Y. -K. Wu, J. Ye +16
A large qubit capacity and an individual readout capability are two crucial requirements for large-scale quantum computing and simulation. As one of the leading physical platforms…
