Heterodyne detection enhanced by quantum correlation
Boya Xie, Sheng Feng
Heterodyne detectors as phase-insensitive (PI) devices have found important applications in precision measurements such as space-based gravitational-wave (GW) observation. However,…

A model independent study of nonlocality with polarization entangled photons
Boya Xie, Sheng Feng
Nonlocality as a fundamental aspect of quantum mechanics is witnessed by violation of Bell inequality or its variants, for which all relevant studies assume some correlations exhib…

Direct Observation of Instantaneous Influence between Entangled Photons
Boya Xie, Peng Yang, Guanyang Zhang +4
We investigate direct observation of quantum nonlocality without reference to theoretical models (including Bell theorem) except quantum mechanics, with a bipartite polarization-en…
