Resolving starlight: a quantum perspective

M Tsang - Contemporary Physics, 2019 - Taylor & Francis
The wave-particle duality of light introduces two fundamental problems to imaging, namely,
the diffraction limit and the photon shot noise. Quantum information theory can tackle them …

Quantum theory of superresolution for two incoherent optical point sources

M Tsang, R Nair, XM Lu - Physical Review X, 2016 - APS
Rayleigh's criterion for resolving two incoherent point sources has been the most influential
measure of optical imaging resolution for over a century. In the context of statistical image …

Ultimate precision bound of quantum and subwavelength imaging

C Lupo, S Pirandola - Physical review letters, 2016 - APS
We determine the ultimate potential of quantum imaging for boosting the resolution of a far-
field, diffraction-limited, linear imaging device within the paraxial approximation. First, we …

Sub-Rayleigh-diffraction-bound quantum imaging

V Giovannetti, S Lloyd, L Maccone, JH Shapiro - Physical Review A, 2009 - APS
The spatial resolution of an imaging apparatus is limited by the Rayleigh diffraction bound, a
consequence of the imager's finite spatial extent. We show some N-photon strategies that …

Resolution-enhanced quantum imaging by centroid estimation of biphotons

E Toninelli, PA Moreau, T Gregory, A Mihalyi, M Edgar… - Optica, 2019 - opg.optica.org
The spatial resolution of an optical system is limited by diffraction. Various schemes have
been proposed to achieve resolution enhancement by employing either a scanning …

Multiparameter quantum metrology of incoherent point sources: towards realistic superresolution

J Řehaček, Z Hradil, B Stoklasa, M Paúr, J Grover… - Physical Review A, 2017 - APS
We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating
the centroid, the separation, and the relative intensities of two incoherent optical point …

Subdiffraction incoherent optical imaging via spatial-mode demultiplexing

M Tsang - New Journal of Physics, 2017 - iopscience.iop.org
I propose a spatial-mode demultiplexing (SPADE) measurement scheme for the far-field
imaging of spatially incoherent optical sources. For any object too small to be resolved by …

Quantum-inspired superresolution for incoherent imaging

XJ Tan, L Qi, L Chen, AJ Danner, P Kanchanawong… - Optica, 2023 - opg.optica.org
Optical measurements that can achieve the fundamental quantum limits have the potential to
improve the imaging of subdiffraction objects in important applications, including optical …

Quantum limits to incoherent imaging are achieved by linear interferometry

C Lupo, Z Huang, P Kok - Physical Review Letters, 2020 - APS
We solve the general problem of determining, through imaging, the three-dimensional
positions of N weak incoherent pointlike emitters in an arbitrary spatial configuration. We …

[HTML][HTML] Smart quantum statistical imaging beyond the Abbe-Rayleigh criterion

N Bhusal, M Hong, A Miller, MA Quiroz-Juárez… - npj Quantum …, 2022 - nature.com
The wave nature of light imposes limits on the resolution of optical imaging systems. For
over a century, the Abbe-Rayleigh criterion has been utilized to assess the spatial resolution …
