Quantum theory of cross-correlation heterodyne detection
Sheng Feng, Kaikai Wu
Cross-correlation heterodyne detectors exhibit the potential for suppression of the detection quantum noise below shot noise without use of optical squeezing for capturing weak opt…
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…
Measuring the continuous variable quantum entanglement with a parametric amplifier assisted homodyne detection
Jiamin Li, Yuhong Liu, Nan Huo +4
Traditional method for measuring continuous-variable quantum entanglement relies on balanced homodyne detections, which are sensitive to vacuum quantum noise coupled in through los…
