Efficient photo-ionizing elimination of detrimental electric fields for Rydberg atoms
Zhou-Chen Deng, Hao-Nan Lin, Yu-Cheng Duan +10
Rydberg atoms are highly sensitive to external electric fields due to their exaggerated electronic properties. This unique feature lays the foundation for many of their application…
Hierarchical Logical Processor on the Rotated Surface Code with Shuttle Buses
Zi-Han Chen, Ming-Cheng Chen, Chao-Yang Lu +1
Quantum platforms with beyond-planar connectivity provide new opportunities for fault-tolerant quantum computation (FTQC). While quantum low-density parity-check (qLDPC) codes offe…
Squeezed-slit Bohr-Einstein Interferometer
Hao-Wen Cheng, Xu-Zhao-Qiu Zeng, Yu-Chen Zhang +9
The Einstein-Bohr recoiling-slit gedankenexperiment, a cornerstone of quantum complementarity, has long been constrained by the zero-point fluctuations of the atomic slit -- the sp…
Taming Rydberg Decay with Measurement-based Quantum Computation
Cheng-Cheng Yu, Zi-Han Chen, Yu-Hao Deng +3
Programmable neutral atom arrays show great promise for fault-tolerant quantum computing. A dominant physical error on this platform is qubit leakage and loss, notably decay errors…
Locating Rydberg Decay Error in SWAP-Leakage Reduction Circuit Protocol
Cheng-Cheng Yu, Yu-Hao Deng, Ming-Cheng Chen +2
Qubit leakage and loss, particularly Rydberg-induced decay during two-qubit gates, pose significant challenges to fault-tolerant quantum computing with neutral atom arrays, as they…
Quantifying Quantum Computational Advantage on a Processor of Ultracold Atoms
Yong-Guang Zheng, Ying-Chao Shen, Wei-Yong Zhang +15
