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…
Realization of a crosstalk-avoided quantum network node with dual-type qubits by the same ion species
L. Feng, Y. -Y Huang, Y. -K. Wu +12
Generating ion-photon entanglement is a crucial step for scalable trapped-ion quantum networks. To avoid the crosstalk on memory qubits carrying quantum information, it is common t…
Realizing coherently convertible dual-type qubits with the same ion species
H. -X. Yang, J. -Y. Ma, Y. -K. Wu +7
Trapped ions constitute one of the most promising systems for implementing quantum computing and networking. For large-scale ion-trap-based quantum computers and networks, it is cr…
