Attaining quantum limited precision of localizing an object in passive imaging
Aqil Sajjad, Michael R Grace, Quntao Zhuang +1
We investigate our ability to determine the mean position, or centroid, of a linear array of equally-bright incoherent point sources of light, whose continuum limit is the problem…

Quantum-Enhanced Fiber-Optic Gyroscopes Using Quadrature Squeezing and Continuous Variable Entanglement
Michael R Grace, Christos N. Gagatsos, Quntao Zhuang +1
We analyze a fiber-optic gyroscope design enhanced by the injection of quantum-optical squeezed vacuum into a fiber-based Sagnac interferometer. In the presence of fiber loss, we c…

Approaching Quantum Limited Super-Resolution Imaging without Prior Knowledge of the Object Location
Michael R Grace, Zachary Dutton, Amit Ashok +1
A recently identified class of receivers which demultiplex an optical field into a set of orthogonal spatial modes prior to detection can surpass canonical diffraction limits on sp…
