Cavity locking with spatial modulation of optical phase front for laser stabilization
Sheng Feng, Songqing You, Peng Yang +3
We study optical cavity locking for laser stabilization through spatial modulation of the phase front of a light beam. A theoretical description of the underlying principle is deve…
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…
Experimental Study of Quantum Noise in Optical Heterodyne Detection
Dechao He, Boya Xie, Yu Xiao +1
We experimentally investigate the quantum-noise performance of a conventional heterodyne detector and find significant discrepancy between experiment and theory. Further investigat…
Quantum Noise in Conventional Optical Heterodyne Devices
Dechao He, Boya Xie, Yu Xiao +1
By invoking the quantum theory of optical coherence, we theoretically show that the quantum noise in conventional optical heterodyne devices, which were previously identified as us…
