Sub-SQL electronic field sensing by simultaneously using quantum entanglements and squeezings
X. N. Feng, M. Zhang, L. F. Wei
Quantum entanglement and quantum squeezing are two most typical approaches to beat the standard quantum limit (SQL) of the sensitive phase estimations in quantum metrology. Each of…

Robust phase metrology with hybrid quantum interferometers against particle losses
X. N. Feng, D. He, L. F. Wei
Entanglement is an important quantum resource to achieve high sensitive quantum metrology. However, the rapid decoherence of quantum entangled states, due to the unavoidable enviro…
