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…
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…
Performance Analysis of Free-space Quantum Key Distribution Using Multiple Spatial Modes
Wenhua He, Saikat Guha, Jeffrey H. Shapiro +1
In the diffraction-limited near-field propagation regime, free-space optical quantum key distribution (QKD) systems can employ multiple spatial modes to improve their key rate. Her…
