This innovative scanning approach improves signal-to-noise ratio in biphoton phase imaging, suggesting better quantum imaging outcomes in challenging environments.
Biphoton phase imaging via two-photon coincidence detection is essential for quantum holography and related quantum imaging applications. Although camera-based methods have been predominantly used in previous studies, we here introduce a two-dimensional scanning method for biphoton phase imaging in quantum holography, which leverages a high-efficiency single-photon detector, improving signal-to-noise ratio (SNR). Using this platform, we obtained a quantum holographic phase image with an SNR above 19 and experimentally verified the noise-resilient nature of quantum holography under scanning-based detection. By using the brighter quantum sources, our method offers an efficient route toward faster two-photon coincidence imaging, which is expected to facilitate broader applications of quantum imaging in noisy environments.
