Sub-Rayleigh Imaging of Unequal-Intensity Sources: Near-Quantum-Limit Multiparameter Estimation
Y. Batuhan Yilmaz, Kent A. G. Bonsma-Fisher, Muhammad Mohid +3
In optical imaging, diffraction strongly degrades the performance of conventional intensity-based estimation once the separation between two sources is below the Rayleigh-Abbe limi…

Information gain and measurement disturbance for quantum agents
Arthur O. T. Pang, Noah Lupu-Gladstein, Y. Batuhan Yilmaz +4
The traditional formalism of quantum measurement (hereafter ``TQM'') describes processes where some properties of quantum states are extracted and stored as classical information.…

Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a…
