All-digital quantum ghost imaging using patterns generated by the Ising model

We present new illumination patterns for quantum ghost imaging (GI) systems that are entirely digital. The digital patterns are produced using the well-known ferromagnetic Ising model and stored as computer-generated holograms on spatial light modulators (SLM). In general, Ising patterns are affected by two parameters: temperature (T) and magnetic field (H). Here, we set H to 0 and offer a method for applying Ising patterns made with various T values to produce high-quality images in relation to the random pattern scheme.
