“…[19][20][21] Particular attention has been attracted by the possibility of nonlocal measurement configurations with the purpose of completely remote sample characterization, which has been already demonstrated in several configurations using classical and quantum correlations. [22][23][24][25][26] Recently, we have developed a theoretical model aiming at coincidence-based discrimination of polarization objects out of a predefined set, where the number of projective measurements for sample identification is significantly reduced and which can be performed remotely by employing polarization-entangled photon pairs. 27 This measurement approach can be implemented with the optical arrangement depicted in Fig.…”

For a wide range of applications, a fast, non-destructive, remote, and sensitive identification of samples with predefined characteristics is preferred instead of their full characterization. In this work, we report on the experimental implementation of a nonlocal quantum measurement scheme, which allows for differentiation among samples out of a predefined set of transparent and birefringent objects in a distant optical channel. The measurement is enabled by application of polarization-entangled photon pairs and is based on remote state preparation. On an example set of more than 80 objects characterized by different Mueller matrices, we show that only two coincidence measurements are already sufficient for successful discrimination. The number of measurements needed for sample differentiation is significantly decreased compared to a comprehensive polarimetric analysis. Our results demonstrate the potential of this polarization detection method for polarimetric applications in biomedical diagnostics, remote sensing, and other classification/detection tasks.

“…This method operates under verylow signal to noise ratio(SNR) situations and separates the spectral components of the signal and noise. Such initiatives for a polarized object appear to not attract much attention except for some recent investigations in the context of ghost polarimetry [55][56][57], lensless stokes holography [58] and higher order stokes correlations [59], etc. Polarization fluctuations in the random field affect the speckle contrast and degree of polarization.…”

Imaging through random scatterer is a challenging problem due to spatial scrambling of the light wavefront and formation of the speckle pattern. Here, we present a new experimental configuration in holography with a two-point intensity correlation to reconstruct the orthogonal polarization modes from a single shot measurement of the speckle pattern.A speckle free orthogonal polarization modes are reconstructed by applying the ensemble averaging in the correlation analysis. Both orthogonal polarization components of the object are simultaneously reconstructed using an edge point referencing for holography with the coherence waves and with a specially designed tunable beam displacer. This tunable beam displacer supports independent recording of the orthogonally polarized speckles at different spatial locations, and hence supports simultaneous reconstruction the orthogonal polarization components of the object from the random light.

“…The technique has particular potential for imaging under turbulent [4][5][6][7] or low-light-level conditions [8] as well as in harsh environments where conventional imaging methods are hard or impossible to implement [9]. Recently, ghost imaging has been demonstrated in such diverse applications as x-ray [10], atom [11], and neutron [12] imaging, as well as in encryption [13], spectroscopy [14], ellipsometry [15,16], and polarimetry using Stokes correlations [17].…”

We introduce a phase-contrast ghost-imaging scheme for the characterization of temporal phase objects in terms of intensity correlations at two photodetectors. The technique is analogous to Zernike's phase-contrast imaging method and is based on utilizing a suitable filter function which renders the small-amplitude phase variations visible in the intensity correlation function. The approach is insensitive to temporal distortions and offers a promising method to analyze the phases of optical pulses.
