Attaining Fundamental Limits of Multiparameter Incoherent Optical Imaging Using Joint-Detection Quantum Measurements
Nico Deshler, Aakash Warke, Michael R. Grace +2
Resolving extended incoherent objects below the diffraction limit poses an application-rich imaging challenge whose solution may enable a new generation of observational instrument…
Incoherent Imaging with Spatially Structured Quantum Probes
Anthony J. Brady, Zihao Gong, Alexey V. Gorshkov +1
Incoherent imaging, including fluorescence and absorption microscopy, is often limited by weak signals and resolution constraints -- notoriously, Rayleigh's curse. We investigate h…
Optimal single-mode squeezing for beam displacement sensing
Wenhua He, Christos N. Gagatsos, Dalziel J. Wilson +1
Estimation of an optical beam's transverse displacement is a canonical imaging problem fundamental to numerous optical imaging and sensing tasks. Quantum enhancements to the measur…
Towards Quantum Limited Spatial Resolution of NV-Diamond Magnetometry
Nico Deshler, Declan Daly, Ayan Majumder +2
Optically addressable ensembles of solid-state defects, such as nitrogen vacancy (NV) centers, are a leading modality for imaging-based magnetometry, thermometry and strain sensing…
Quantum limited imaging of a nanomechanical resonator with a spatial mode sorter
Morgan Choi, Christian Pluchar, Wenhua He +2
We explore the use of a spatial mode sorter to image a nanomechanical resonator, with the goal of studying the quantum limits of active imaging and extending the toolbox for optome…
Imaging-based Quantum Optomechanics
Christian M. Pluchar, Wenhua He, Jack Manley +3
In active imaging protocols, information about an object is encoded into the spatial mode of a scattered photon. Recently the quantum limits of active imaging have been explored wi…
