We experimentally demonstrate a quantum polarized microscopic technique utilizing a quantum-entangled photon source. Unlike classical methods, image contrast is constructed by coincident count of signal and idler photons. In the case that coincident count is recorded from both the signal and idler photons, the photon statistics is thermal state similarly as the case of black body radiation, but its peak intensity appearing in coincidentally counting is significantly high. While, when the coincident count is taken from either the signal or idler photon only, though the photon state exhibits thermal state again, the photon statistics becomes more dispersive and thereby its peak intensity is lowered. These different thermal states can be switched by perturbing the photon polarization, which enable us polarization-enhanced imaging. Since this approach achieves enhanced image contrast with minimal illumination power (on the order of Pico joule), offering a significant advancement in biomedical microscopy.
