Photonic state engineering via energy-level crossing by giant atoms in topological waveguide QED setup
Mingzhu Weng, Gang Wang, Zhihai Wang
Photonic state engineering in waveguide QED is typically based on local light-matter interactions. This limits its control over the spatial structure of bound photonic states. Here…

Multipartite steering verification with imprecise measurements
Zeyang Lu, Chan Li, Gang Wang +1
Quantum steering is a fundamental quantum correlation that plays a pivotal role in quantum technologies, but its verification crucially relies on precise measurements -- an assumpt…

Observation of quantum superposition of topological defects in a trapped ion quantum simulator
Zhijie Cheng, Yukai Wu, Shijiao Li +8
Topological defects are discontinuities of a system protected by global properties, with wide applications in mathematics and physics. While previous experimental studies mostly fo…
