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…
