Observing mixed-state Uhlmann winding numbers in integrated photonic quantum walks
Baichu Yu, Qin-Qin Wang, Huilong Huang +7
Integer winding numbers provide a well-established classification of topological phases protected by chiral symmetry at zero temperature, but extending this classification to therm…
A single programmable photonic circuit for universal quantum measurements
Wen-Zhe Yan, Lan-Tian Feng, Zhibo Hou +7
Programmable photonic quantum processors face a critical challenge: despite significant advances in quantum state preparation and manipulation, measurements remain limited to proje…
Characterization-free classification and identification of the environment between two quantum players
Masahito Hayashi, Longyang Cao, Baichu Yu +1
Identifying the causal structure of quantum channels is essential for verifying quantum networks and certifying quantum resources. We introduce a characterization-free protocol ena…
