Topological enhancement of a PT-symmetric Su-Schrieffer-Heeger quantum battery
A-Long Zhou, Ya-Wen Xiao, Nuo Xu +5
We investigate a non-Hermitian quantum battery based on the Su-Schrieffer-Heeger (SSH) lattice, charged through a parity-time (PT)-symmetric protocol that alternates gain and loss…

Experimental demonstration of Contextual Advantage in minimum error and maximum confidence mirror-state discrimination
Xuan Fan, Ya Xiao, Yongjian Gu
Contextuality is well known as a vital resource for locating the boundary between classical and quantum theories, as well as identifying tasks showing quantum advantage. In a surge…
