Suppression of Universal Errors in DFS-Encoded Superconducting Geometric Logical \emph{T} Gate
Cheng-Yun Ding, Li-Hua Zhang, Jian Zhou
High-fidelity logical \emph{T}-gate realization constitutes a core prerequisite for large-scale fault-tolerant quantum computing. However, conventional magic state distillation req…
Crosstalk-robust superconducting two-qubit geometric gates using tunable couplers
Bo-Xun Deng, Jia-Qi Hu, Cheng-Yun Ding +2
The design of coupler-based superconducting two-qubit gates simplifies circuit layout and alleviate frequency crowding, thereby enhancing the scalability and flexibility of quantum…
Composite nonadiabatic geometric quantum gates with optimization on superconducting circuits
Cheng-Yun Ding, Wan-Fang Liu, Li-Hua Zhang +2
Due to its fast and robust characteristics, nonadiabatic geometric quantum computation with various optimized techniques has received much attention. However, these strategies eith…
Fusion of atomic W-like states in cavity QED systems
Cheng-Yun Ding, Wan-Fang Liu, Li-Hua Zhang
It is well-known that maximally entangled GHZ states can achieve perfect teleportation and superdense coding, whereas maximally entangled W states cannot. However, it has been demo…
