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…
Entangling gates for trapped-ion quantum computation and quantum simulation
Zhengyang Cai, Chunyang Luan, Lingfeng Ou +4
The trapped-ion system has been a leading platform for practical quantum computation and quantum simulation since the first scheme of a quantum gate was proposed by Cirac and Zolle…
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…
Observing frustrated quantum magnetism in two-dimensional ion crystals
Mu Qiao, Zhengyang Cai, Ye Wang +10
Two-dimensional (2D) quantum magnetism is a paradigm in strongly correlated many-body physics. The understanding of 2D quantum magnetism can be expedited by employing a controllabl…
Fast multi-qubit global-entangling gates without individual addressing of trapped ions
Kaizhao Wang, Jing-Fan Yu, Pengfei Wang +3
We propose and study ways speeding up of the entangling operations in the trapped ions system with high fidelity. First, we find a scheme to increase the speed of a two-qubit gate…
Significant-loophole-free test of Kochen-Specker contextuality using two species of atomic-ions
Pengfei Wang, Junhua Zhang, Chun-Yang Luan +7
Quantum measurements cannot be thought of as revealing preexisting results, even when they do not disturb any other measurement in the same trial. This feature is called contextual…
Single ion-qubit exceeding one hour coherence time
Pengfei Wang, Chun-Yang Luan, Mu Qiao +7
Realizing a long coherence time quantum memory is a major challenge of current quantum technology. Here, we report a single \Yb ion-qubit memory with over one hour coherence time,…
Double-EIT Ground-State Cooling of Stationary Two-Dimensional Ion Lattices
Mu Qiao, Ye Wang, Zhengyang Cai +6
We theoretically and experimentally investigate double electromagnetically induced transparency (double-EIT) cooling of two-dimensional ion crystals confined in a Paul trap. The do…
Realization of two-dimensional crystal of ions in a monolithic Paul trap
Ye Wang, Mu Qiao, Zhengyang Cai +9
We present a simple Paul trap that stably accommodates up to a couple of dozens of \ensuremath{^{171}\mathrm{Yb}^+~} ions in a stationary two-dimensional lattice. The trap is const…
