2019 · arXiv (Cornell University)

In relation extraction for knowledge-based question answering, searching from one entity to another entity via a single relation is called "one hop". In related work, an exhaustive search from all one-hop relations, two-hop relations, and …

Single-pulse two-qubit gates for Rydberg atoms with noncyclic geometric control

2024 · Physical Review A

Arrays of neutral atoms have emerged as promising platforms for quantum computing. The realization of high-fidelity two-qubit gates with robustness is currently a significantly important task for large-scale operations. In this paper, we present a …
