Spontaneous optical emission of a randomly oriented chiral quantum source
Mikael P. Backlund
We derive the form of the one-photon state of the electromagnetic field resulting from spontaneous optical emission of a randomly oriented chiral quantum source, including electric…
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…
Quantum sensing in the fractional Fourier domain
Swastik Hegde, David J. Durden, Lakshmy Priya Ajayakumar +2
Certain quantum sensing protocols rely on qubits that are initialized, coherently driven in the presence of a stimulus to be measured, then read out. Most widely employed pulse seq…
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…
Quantum limits to resolution and discrimination of spontaneous emission lifetimes
Cheyenne S. Mitchell, Mikael P. Backlund
In this work we investigate the quantum information theoretical limits to several tasks related to lifetime estimation and discrimination of a two-level spontaneous optical emitter…
Quantum diamond spectrometer for nanoscale NMR and ESR spectroscopy
Dominik B. Bucher, Diana P. L. Aude Craik, Mikael P. Backlund +4
Nitrogen-vacancy (NV) quantum defects in diamond are sensitive detectors of magnetic fields. Due to their atomic size and optical readout capability, they have been used for magnet…
Fundamental precision bounds for three-dimensional optical localization microscopy with Poisson statistics
Mikael P. Backlund, Yoav Shechtman, Ronald L. Walsworth
Point source localization is a problem of persistent interest in optical imaging. In particular, a number of widely used biological microscopy techniques rely on precise three-dime…
Fourier optical processing enables new capabilities in diamond magnetic imaging
Mikael P. Backlund, Pauli Kehayias, Ronald L. Walsworth
Diamond-based magnetic field sensors have attracted great interest in recent years. In particular, wide-field magnetic imaging using nitrogen-vacancy (NV) centers in diamond has be…
