Quantitative phase gradient microscopy with spatially entangled photons
Yingwen Zhang, Paul-Antoine Moreau, Duncan England +2
We present an entanglement-based quantitative phase gradient microscopy technique that employs principles from quantum ghost imaging and ghost diffraction. In this method, a transp…
Imaging below the camera noise floor with a homodyne microscope
Osian Wolley, Simon Mekhail, Paul-Antoine Moreau +4
We present a wide-field homodyne imaging system capable of recovering intensity and phase images of an object from a single camera frame at an illumination intensity significantly…
Imaging spatio-temporal Hong-Ou-Mandel interference of bi-photon state of extremely high Schmidt number
Fabrice Devaux, Alexis Mosset, Paul-Antoine Moreau +1
We report the experimental observation of a spatio-temporal Hong-Ou-Mandel (HOM) interference of bi-photon states of extremely high Schmidt number. Two-photon interference of 1500…
A model for the detection of spatially correlated biphotons using a photon-counting camera
Ermes Toninelli, Paul-Antoine Moreau, Thomas Gregory +1
Spontaneous downconversion is a versatile source for correlated biphotons that has been employed in many quantum sensing and imaging experiments. Spatially-resolved photon-counting…
A Gigapixel Computational Light-Field Camera
Thomas Gregory, Matthew P. Edgar, Graham M. Gibson +1
Light-field cameras allow the acquisition of both the spatial and angular components of the light. This has a wide range of applications from image refocusing to 3D reconstruction…
Imaging with quantum states of light
Paul-Antoine Moreau, Ermes Toninelli, Thomas Gregory +1
The production of pairs of entangled photons simply by focusing a laser beam onto a crystal with a non-linear optical response was used to test quantum mechanics and to open new ap…
Imaging Through Noise With Quantum Illumination
Thomas Gregory, Paul-Antoine Moreau, Ermes Toninelli +1
The contrast of an image can be degraded by the presence of background light and sensor noise. To overcome this degradation, quantum illumination protocols have been theorised (Sci…
Phase and amplitude imaging with quantum correlations through Fourier Ptychography
Tomas Aidukas, Pavan Chandra Konda, Andrew R. Harvey +2
Extracting as much information as possible about an object when probing with a limited number of photons is an important goal with applications from biology and security to metrolo…
Twin-beam sub-shot-noise raster-scanning microscope with a hybrid detection scheme
J. Sabines-Chesterking, A. R. McMillan, P. A. Moreau +5
By exploiting the quantised nature of light, we demonstrate a sub-shot-noise scanning optical transmittance microscope. Our microscope demonstrates, with micron scale resolution, a…
Temporal ghost imaging with twin photons
Séverine Denis, Paul-Antoine Moreau, Fabrice Devaux +1
We use twin photons generated by spontaneous parametric down conversion (SPDC) to perform temporal ghost imaging of a single time signal. The retrieval of a binary signal containin…
Demonstrating an absolute quantum advantage in direct absorption measurement
Paul-Antoine Moreau, Javier Sabines-Chesterking, Rebecca Whittaker +5
Engineering apparatus that harness quantum theory offers practical advantages over current technology. A fundamentally more powerful prospect is the long-standing prediction that s…
Sub-shot-noise transmission measurement using optically gated single photons
J. Sabines-Chesterking, R. Whittaker, S. K. Joshi +7
Harnessing the unique properties of quantum mechanics offers the possibility to deliver new technologies that can fundamentally outperform their classical counterparts. These techn…
Temporal ghost imaging with pseudo-thermal speckle light
Fabrice Devaux, Kien Phan Huy, Paul-Antoine Moreau +2
We report ghost imaging of a single non-reproducible temporal signal in the range of tens kHz by using pseudo-thermal speckle light patterns and a single detector array with a mill…
Computational temporal ghost imaging
Fabrice Devaux, Paul-Antoine Moreau, Severine Denis +1
Ghost imaging is a fascinating process, where light interacting with an object is recorded without resolution, but the shape of the object is nevertheless retrieved, thanks to quan…
Einstein-Podolsky-Rosen paradox in single pairs of images
Eric Lantz, Séverine Denis, Paul-Antoine Moreau +1
Spatially entangled twin photons provide a test of the Einstein-Podolsky-Rosen (EPR) paradox in its original form of position (image plane) versus impulsion (Fourier plane). We sho…
Optimising the signal-to-noise ratio in measurement of photon pairs with detector arrays
Eric Lantz, Paul-Antoine Moreau, Fabrice Devaux
To evidence multimode spatial entanglement of spontaneous down-conversion, detector arrays allow a full field measurement, without any a priori selection of the paired photons. We…

Paul-Antoine Moreau, Fabrice Devaux, Eric Lantz
Spatially entangled twin photons provide both promising resources for modern quantum information protocols, because of the high dimensionality of transverse entanglement, and a tes…
