Deterministic atom-shuttle interconnects via ultrafast atom-ion entangling gate

Mu Qiao

Neutral-atom arrays and trapped-ion crystals offer complementary strengths for fault-tolerant quantum computing but lack a fast way to deterministically interact. Here we propose a…

A Single-Ion Information Engine for Charging Quantum Battery

Jialiang Zhang, Pengfei Wang, Wentao Chen +12

Information engines produce mechanical work through measurement and adaptive control. For information engines, the principal challenge lies in how to store the generated work for s…

Error-Mitigated Quantum Simulation of Interacting Fermions with Trapped Ions

Wentao Chen, Shuaining Zhang, Jialiang Zhang +7

Quantum error mitigation has been extensively explored to increase the accuracy of the quantum circuits in noisy-intermediate-scale-quantum (NISQ) computation, where quantum error…

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…

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…

Randomness expansion secured by quantum contextuality

Mark Um, Qi Zhao, Junhua Zhang +6

The output randomness from a random number generator can be certified by observing the violation of quantum contextuality inequalities based on the Kochen-Specker theorem. Contextu…
