Off-axis Aberrations Improve the Resolution Limits of Incoherent Imaging
Kevin Liang
The presence of off-axis tilt and Petzval curvature, two of the lowest-order off-axis Seidel aberrations, is shown to improve the Fisher information of two-point separation estimat…
Coherence effects on estimating general sub-Rayleigh object distribution moments
Kevin Liang, S. A. Wadood, A. N. Vamivakas
Quantum Fisher information and signal-to-noise ratio bounds are derived for the estimation of moments of general partially coherent objects. Under an asymptotic analysis in the sub…
Experimental demonstration of superresolution of partially coherent light sources using parity sorting
S. A. Wadood, Kevin Liang, Yiyu Zhou +8
Analyses based on quantum metrology have shown that the ability to localize the positions of two incoherent point sources can be significantly enhanced through the use of mode sort…
Coherence effects on estimating two-point separation
Kevin Liang, S. A. Wadood, A. N. Vamivakas
The quantum Fisher information (FI), when applied to the estimation of the separation of two point sources, has been shown to be non-zero in cases where the coherence between the s…
Theoretical analysis of quantum random walks with stress-engineered optics
Kevin Liang, Ashan Ariyawansa, Thomas G. Brown +1
Quantum random walks (QRWs) are random processes in which the resulting probability density of the "walker" state, whose movement is governed by a "coin" state, is described in a n…
