Pixel super-resolution using spatially-entangled photon pairs
Hugo Defienne, Patrick Cameron, Bienvenu Ndagano +7
Pixelation occurs in many imaging systems and limits the spatial resolution of the acquired images. This effect is notably present in quantum imaging experiments with correlated ph…
Three-Photon Absorption Spectra and Bandgap Scaling in Direct-Gap Semiconductors
Sepehr Benis, Claudiu M. Cirloganu, Nicholas Cox +11
This paper presents three-photon absorption (3PA) measurement results for nine direct-gap semiconductors, including full 3PA spectra for ZnSe, ZnS, and GaAs. These results, along w…
Quantum image distillation
Hugo Defienne, Matthew Reichert, Jason W Fleischer +1
Imaging with quantum states of light promises advantages over classical approaches in terms of resolution, signal-to-noise ratio and sensitivity. However, quantum detectors are par…
Adaptive Quantum Optics with Spatially Entangled Photon Pairs
Hugo Defienne, Matthew Reichert, Jason W. Fleischer
Light shaping facilitates the preparation and detection of optical states and underlies many applications in communications, computing, and imaging. In this Letter, we generalize l…
Optimizing the signal-to-noise ratio of biphoton distribution measurements
Matthew Reichert, Hugo Defienne, Jason W. Fleischer
Single-photon-sensitive cameras can now be used as massively parallel coincidence counters for entangled photon pairs. This enables measurement of biphoton joint probability distri…
General model of photon-pair detection with an image sensor
Hugo Defienne, Matthew Reichert, Jason W. Fleischer
We develop an analytic model that relates intensity correlation measurements performed by an image sensor to the properties of photon pairs illuminating it. Experiments using both…
Massively Parallel Coincidence Counting of High-Dimensional Entangled States
Matthew Reichert, Hugo Defienne, Jason W. Fleischer
Quantum entangled states of light are essential for quantum technologies and fundamental tests of physics. While quantum information science has relied on systems with entanglement…
Biphoton transmission through non-unitary objects
Matthew Reichert, Hugo Defienne, Xiaohang Sun +1
Losses should be accounted for in a complete description of quantum imaging systems, and yet they are often treated as undesirable and largely neglected. In conventional quantum im…
Quality of Spatial Entanglement Propagation
Matthew Reichert, Xiaohang Sun, Jason W. Fleischer
We explore, both experimentally and theoretically, the propagation dynamics of spatially entangled photon pairs (biphotons). Characterization of entanglement is done via the Schmid…
Observation of Nondegenerate Two-Photon Gain in GaAs
Matthew Reichert, Arthur L. Smirl, Greg Salamo +2
Two-photon lasers require materials with large two-photon gain (2PG) coefficients and low linear and nonlinear losses. Our previous demonstration of large enhancement of two-photon…
Enhancement of Two-photon Absorption in Quantum Wells for Extremely Nondegenerate Photon Pairs
Himansu S. Pattanaik, Matthew Reichert, Jacob B. Khurgin +2
We recently demonstrated orders of magnitude enhancement of two-photon absorption (2PA) in direct gap semiconductors due to intermediate state resonance enhancement for photons of…
3-D IR imaging with uncooled GaN photodiodes using nondegenerate two-photon absorption
Himansu S. Pattanaik, Matthew Reichert, David J. Hagan +1
We utilize the recently demonstrated orders of magnitude enhancement of extremely nondegenerate two-photon absorption in direct-gap semiconductor photodiodes to perform scanned ima…
Quantum Phase Imaging using Spatial Entanglement
Chien-Hung Lu, Matthew Reichert, Xiaohang Sun +1
Entangled photons have the remarkable ability to be more sensitive to signal and less sensitive to noise than classical light. Joint photons can sample an object collectively, resu…
Tailored quantum statistics from broadband states of light
S. Hartmann, F. Friedrich, A. Molitor +3
We analyze the statistics of photons originating from amplified spontaneous emission generated by a quantum dot superluminescent diode. Experimentally detectable emission propertie…
