Geometry-Resolved Projection of RF Imbalance to Ion Micromotion in a Same-Phase Dual-RF Blade Trap
Chun-Yang Luan, Haiyu Ding, Cheng-Kang Pan +8
Common-mode metrics of a high- helical resonator do not determine the residual ion-side field in a dual-electrode drive. We combine a two-node differential RF model with single-…
Boundary-Phase Control of Sequentially Addressed Trapped-Ion ZZ Interactions
Chun-Yang Luan, Haiyu Ding, Cheng-Kang Pan +8
Motion-mediated trapped-ion interactions commonly coordinate state-dependent forces on both target ions. Sequential optical access reduces the number of concurrent target channels…
Stream randomness extraction against quantum side information
Chun-Yang Luan, Cheng-Kang Pan, Xiang Zhang +1
Randomness extraction is indispensable for quantum random number generators, serving to eliminate bias and potential information leakage from raw measurement data. Conventional ext…
Real-Time Quantum Error Correction System Stack: Architecture, Algorithms, and Engineering Practice
Yaojian Chen, Chun-Yang Luan, Peilin Zheng +7
Quantum error correction (QEC) is transitioning from physical feasibility demonstrations to systems engineering challenges. Google has achieved below-threshold performance on dista…
Precision Polarization Tuning for Light Shift Mitigation in Trapped-Ion Qubits
Hengchao Tu, Chun-Yang Luan, Menglin Zou +3
Trapped-ion qubits are among the most promising candidates for quantum computing, quantum information processing, and quantum simulation. In general, trapped ions are considered to…
Snapshotting Quantum Dynamics at Multiple Time Points
Pengfei Wang, Hyukjoon Kwon, Chun-Yang Luan +6
Measurement-induced state disturbance is a major challenge in obtaining quantum statistics at multiple time points. We propose a method to extract dynamic information from a quantu…
