600-km repeater-like quantum communications with dual-band stabilization
Nature Photonics
by
3y ago
Twin-field quantum key distribution over 600 km is demonstrated. The key ingredient for success is the dual-band phase stabilization that dramatically reduce the phase fluctuations on optical fibre by more than four orders of magnitude ..read more

Direct observation of the particle exchange phase of photons
Nature Photonics
by
3y ago
An interferometric technique is developed to measure the particle exchange phase of indistinguishable photons. The exchange phase obtained is (−0.04 ± 0.07) radians, which clearly demonstrates the symmetric nature of the two-photon wave functions ..read more

Mid-infrared semimetal polarization detectors with configurable polarity transition
Nature Photonics
by
3y ago
Mid-infrared polarization detectors based on nanoantenna-mediated few-layer graphene are demonstrated. By tuning the orientation of nanoantennas, the polarization ratios vary from positive to negative, and cover values from 1 to ∞/−∞ then to −1 ..read more
