Quantitative phase microscopy (QPM) has emerged as a revolutionary tool, enabling label-free imaging of biological specimens without the need for disruptive dyes or stains 1. This technique preserves ...

We present an entanglement-based quantitative phase gradient microscopy technique that employs principles from quantum ghost imaging and ghost diffraction. In this method, a transparent sample is ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...
