Resolution limit in quantum imaging with undetected photons using position correlations

Balakrishnan Viswanathan, Gabriela Barreto Lemos, Mayukh Lahiri

Quantum imaging with undetected photons (QIUP) is a unique method of image acquisition where the photons illuminating the object are not detected. This method relies on quantum interference and spatial correlations between the twin photons to form an image. Here we present a detailed study of the resolution limits of position correlation enabled QIUP. We establish a quantitative relation between the spatial resolution and the twin-photon position correlation. Furthermore, we also quantitatively establish the roles that the wavelength of the undetected illumination field and the wavelength of the detected field play in the resolution. Like ghost imaging and unlike conventional imaging, the resolution limit imposed by the spatial correlation between the twin photons in QIUP cannot be further improved by conventional optical techniques.

Quantum imaging with undetected photons of non-transmissive target

Chiara Michelini, Ugo Zanforlin, Alessia Suprano +4 more

Quantum imaging with undetected photons (QIUP) is an active imaging method in which the detected and the probing photons are distinct and can be selected from different spectral regions. This technique holds potential for a wide range of applications affected by the trade-off between illumination wavelength and detection efficiency. The state-of-the-art experimental configurations assess the spectral absorption and phase information of a target solely in a transmissive configuration, which presents a limitation for applications where the target cannot be aligned with optical elements positioned behind it. In this work, we present an experimental configuration for QIUP of a scattering target, aiming to fill the gap in the applicability of the QIUP technique and enabling QIUP to detect remote targets.
