Adaptive optics (AO) has revolutionized imaging in fields from astronomy to microscopy by correcting optical aberrations. In label-free microscopes, however, conventional AO faces limitations because of the absence a guide star and need select an optimization metric specific sample process. Here, we propose approach leveraging correlations between entangled photons directly correct point spread function. This star–free method is independent specimen modality. We demonstrate biological samples presence aberrations using bright-field setup operating with source spatially photon pairs. Our performs better than aberrations, particularly those involving substantial defocus. work improves for could play major role development quantum microscopes.

Abstract Certifying entanglement is an important step in the development of many quantum technologies, especially for higher-dimensional systems, where promises increased capabilities communication and computation. A key feature distinguishing from classical correlations occurrence complementary measurement bases. In particular, mutually unbiased bases (MUBs) are a paradigmatic example that well-understood routinely employed certification. However, implementing measurements exactly challenging not generically possible all physical platforms. Here, we extend entanglement-certification toolbox MUBs to arbitrary This practically significant simplification paves way efficient characterizations high-dimensional wide range systems. Furthermore, introduce simple three-MUBs construction dimensions without using Wootters–Fields construction, potentially simplifying experimental requirements when more than two needed, settings.

Abstract Quantitative phase microscopy (QPM) techniques are widely investigated for imaging transparent specimens, such as cells and tissues. The sensitivity resolution of conventionally used QPM fundamentally limited by environmental noise. Recently, quantum has been proposed. research on it made some progress shown many advantages over the classical one, greater robustness higher contrast. However, existing microscopies remains very low, often confined to qualitative measurement level. Here, resolve these practical limitations, we introduced polarization entanglement‐enabled holographic technology into system constructed a new type microscopy, namely microscopy. By improving scheme, our microscope can be measure both various non‐biological samples label‐free biological samples. experimental results show that is improved an order magnitude compared with microscopes. Moreover, good still obtain clear images in presence strong newly microscopic expected have broad applications industrial production, medicine, research, other fields.

Abstract Metasurfaces can precisely manipulate the amplitude, phase, and polarization of incident light through subwavelength structures, greatly advancing quantum meta-holographic imaging. However, current methods using holography only control either amplitude or phase on imaging plane, so resulted scalar without distribution has limited channels. Here, vectorial meta-holography entangled signal-idler photon pairs is experimentally demonstrated to realize remotely controlled multi-channel By simultaneous ratio between two cross-polarization holographic images their difference image accordingly changes with state. The accurate correspondence ensures correct reconstruction 32 states an average fidelity up 94.78%. This enables idler photons reconstructed by signal photons, where signal-to-noise as high 10.78 dB, even for maximally mixed states. a larger state information capacity will facilitate miniaturized efficient tomography.
