Quantifying classical and quantum bounds for resolving closely spaced, non-interacting, simultaneously emitting dipole sources in optical microscopy
Armine I. Dingilian, Aarnah Kurella, Cheyenne S. Mitchell +3
Recent theoretical and experimental work has shown that the quantum Fisher information associated with estimating the separation between two optical point sources remains finite at…

Photoswitchable radicals as reporter spins for quantum sensing with spin defects in diamond
Lakshmy Priya Ajayakumar, David J. Durden, Aksshay Nandakumar Regeni +5
The rapid decay of target signal strength with distance from the sensor presents a key challenge in nanoscale magnetic sensing with nitrogen-vacancy (NV) centers in diamond, limiti…

Quantum-inspired super-resolution of fluorescent point-like sources
Cheyenne S. Mitchell, Dhananjay Dhruva, Zachary P. Burke +3
We report the experimental super-resolution of pairs of point-like fluorescent sources using a modified image inversion interferometer microscope. The technique is inspired by rece…
