Enhanced Atom-by-Atom Assembly of Defect-Free Two-Dimensional Mixed-Species Atomic Arrays
Ming-Rui Wei, Kun-Peng Wang, Jia-Yi Hou +8
Defect-free single atom array in optical tweezers is a promising platform for scalable quantum computing, quantum simulation, and quantum metrology. Extending single-species array…
High fidelity entanglement of neutral atoms via a Rydberg-mediated single-modulated-pulse controlled-PHASE gate
Zhuo Fu, Peng Xu, Yuan Sun +8
Neutral atom platform has become an attractive choice to study the science of quantum information and quantum simulation, where intense efforts have been devoted to the entangling…
Influence of ground-Rydberg coherence in two-qubit gate based on Rydberg blockade
Yangyang Liu, Yuan Sun, Zhuo Fu +5
For neutral atom qubits, the two-qubit gate is typically realized via the Rydberg blockade effect, which hints about the special status of the Rydberg level besides the regular qub…
Efficient preparation of 2D defect-free atom arrays with near-fewest sorting-atom moves
Cheng Sheng, Jiayi Hou, Xiaodong He +7
Sorting atoms stochastically loaded in optical tweezer arrays via an auxiliary mobile tweezer is an efficient approach to preparing intermediate-scale defect-free atom arrays in ar…
Doppler-insensitive two-qubit controlled-PHASE gate protocol with dual-pulse off-resonant modulated driving for neutral atoms
Yuan Sun, Peng Xu, Liang Liu
For neutral atom qubits, the residual thermal motion of the cold atoms constitutes a major challenge that limits the accessible two-qubit gate fidelity. Recently, an interesting ty…

High Fidelity Single-qubit Gates of a Single Neutral Atom in the Magic-Intensity Optical Dipole Trap
Cheng Sheng, Xiaodong He, Ruijun Guo +6
We demonstrate high fidelity single-qubit gate operation in a trapped single neutral atom. The atom is trapped in the recently invented magic-intensity optical dipole trap (MI-ODT)…
Coherence preservation of a single neutral atom qubit transferred between magic-intensity optical traps
Jiaheng Yang, Xiaodong He, Ruijun Guo +7
We demonstrate that the coherence of a single mobile atomic qubit can be well preserved during a transfer process among different optical dipole traps (ODTs). This is a prerequisit…
Suppressing phase decoherence of a single atom qubit with CPMG sequence
Shi Yu, Peng Xu, Xiaodong He +3
We experimentally demonstrate the strong suppression of dephasing of a qubit stored in a single \textsuperscript{87}Rb atom in an optical dipole trap by using Carr-Purcell-Meiboom-…
