Stabilizing Topological Superfluidity of Lattice Fermions
Junhua Zhang, Sumanta Tewari, V. W. Scarola
Attractive interaction between spinless fermions in a two-dimensional lattice drives the formation of a topological superfluid. But the topological phase is dynamically unstable to…
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,…
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…
Frequency stabilization of a 650 nm laser to I spectrum for trapped Ba ions
Tian Xie, Naijun Jin, Ye Wang +4
The optical manipulation of Ba ions is mainly performed by a 493 nm laser for the S-P transition and a 650 nm laser for the P-D transition. Si…
Quantum simulation of molecular spectroscopy in trapped-ion device
Yangchao Shen, Joonsuk Huh, Yao Lu +4
Molecules are the most demanding quantum systems to be simulated by quantum computers because of their complexity and the emergent role of quantum nature. The recent theoretical pr…
Single-qubit quantum memory exceeding -minute coherence time
Ye Wang, Mark Um, Junhua Zhang +6
A long-time quantum memory capable of storing and measuring quantum information at the single-qubit level is an essential ingredient for practical quantum computation and com-munic…
