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…

Tight information bounds for spontaneous emission lifetime resolution of quantum sources with varied spectral purity
Cheyenne S. Mitchell, Mikael P. Backlund
We generalize the theory of resolving a mixture of two closely spaced spontaneous emission lifetimes to include pure dephasing contributions to decoherence, leading to the resurgen…
