Attaining the quantum limit of super resolution in imaging an object's length via pre-detection spatial mode sorting
Zachary Dutton, Ronan Kerviche, Amit Ashok +1
Recent work considered the ultimate (quantum) limit of the precision of estimating the distance between two point objects. It was shown that the performance gap between the quantum…

Fundamental limit of resolving two point sources limited by an arbitrary point spread function
Ronan Kerviche, Saikat Guha, Amit Ashok
Estimating the angular separation between two incoherently radiating monochromatic point sources is a canonical toy problem to quantify spatial resolution in imaging. In recent wor…
