In this talk, we will discuss our recent progress on second-order correlation weak-value measurements. By extending the conventional weak-value measurements to second-order correlation function, in one experiment, we have post-selected a nonlinear observable to improve the sensitivity of EIT-based magnetometry in an atomic vapor cell by few orders of magnitude in comparison to previous reports. In...
The nonclassical photon pair is naturally endowed with a specific form of frequency-time quantum correlations. Here, we report complete control of time quantum correlations of narrowband biphotons generated in a cold atomic ensemble.
We report that quantum discord can be protected from decoherence by making use of weak and reversing quantum measurements, making it possible to distribute quantum correlation between two remote parties in noisy environment.
A specific form of frequency-time quantum correlations is naturally inherent in the nonclassical photon pairs generated via a parametric process. Here, complete manipulation of frequency-time quantum correlations of narrowband biphotons is reported.
We demonstrate that a clear image of an object hidden behind a turbid medium may be obtained by using speckle illumination and correlation measurement whereas coherent illumination only results distorted and blurred images.
We demonstrate a sub-Rayleigh imaging technique based on speckle illumination and the second-order correlation measurement. The image resolution is related to the speckle size or the lateral coherence length of the pseudothermal light.
Using an entangled photon-pair traveling through two separate dispersive media, we experimentally demonstrate nonlocal dispersion cancellation in which the dispersion experienced by one photon cancels the dispersion experienced by the other photon.
In this paper, we proposed the digital watermarking algorithm in the transform domain. The main point of our algorithm is that the embedding system uses the relation of thresholds for watermark insertion. In the first, discrete wavelet transform is involved to calculate energy strength, and then we determined the range for watermark insertion by the priority of interrelation between threshold value...
Experiments on the evaporative heat transfer and pressure drop in the brazed plate heat exchangers were performed with refrigerants R410A and R22. The plate heat exchangers with different 45°, 35°, and 20° chevron angles are used. Varying the mass flux of refrigerant (13–34 kg/m 2 s), the evaporating temperature (5, 10 and 15 °C), the vapor quality (0.9–0.15) and heat flux (2.5, 5.5 and 8...
