Real-time observation of picosecond-timescale optical quantum entanglement towards ultrafast quantum information processing - Nature Photonics
nature.comOptical Einstein–Podolsky–Rosen correlation is observed on a picosecond timescale in a continuous-wave system. By introducing waveguide optical parametric amplifiers and balanced detectors, the quantum correlation 4.5 dB below the shot-noise level is observed.
