Topologically protected measurement of orbital angular momentum of light
Junfan Zhu, An Wang, Yurong Liu +2
We develop a weak measurement scheme for measuring orbital angular momentum (OAM) of light based on the global topology in wave function. We introduce the spin-orbit coupling to tr…

Weak-measurement-based pseudospin pointer: A cost-effective scheme for precision measurement
Ling Ye, Lan Luo, An Wang +2
As an essential component of state-of-the-art quantum technologies, fast and efficient quantum measurements are in persistent demand over time. We present a proof-of-principle expe…
