Quantum radio astronomy: Data encodings and quantum image processing
Jean-Paul Richard Kneib, Emma Elizabeth Tolley, Stefano Corda
We explore applications of quantum computing for radio interferometry and astronomy using recent developments in quantum image processing. We evaluate the suitability of different quantum image representations using a toy quantum computing image reconstruc ...
Elsevier2024Validation of short-pulse reflectometry turbulence measurements with a synthetic diagnostic
Stefano Coda, Stephan Brunner, Oleg Krutkin, Umesh Kumar, Mackenzie Peter-Fulford Van Rossem, Samuele Mazzi
Experimental measurements of the turbulence amplitude utilizing a short pulse reflectometry method are presented. Two discharges with shaped plasma possessing opposite signs of triangularity are considered and a higher turbulence amplitude is found in the ...
Bristol2024Hydrogen Intensity and Real-Time Analysis Experiment: 256-element array status and overview
Jean-Paul Richard Kneib, Emma Elizabeth Tolley, Carolyn Marie Crichton, Zeyu Zhang, Martin Kunz
The Hydrogen Intensity and Real-time Analysis Experiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the South African Radio Astronomy Observatory Square Kilometer Array site in Sout ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2022NIR Fluorescence lifetime macroscopic imaging with a time-gated SPAD camera
Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü
The performance of SwissSPAD2 (SS2), a large scale, widefield time-gated CMOS SPAD imager developed for fluorescence lifetime imaging, has recently been described in the context of visible range and fluorescence lifetime imaging microscopy (FLIM) of dyes w ...
SPIE-INT SOC OPTICAL ENGINEERING2022SBS-based fiber sensors
The spectra of Brillouin scattering processes in optical fibers are affected by temperature, axial strain, and other quantities of interest. This dependence forms the basis for optical Brillouin scattering based optical fiber sensors. Since the first propo ...
Elsevier2022Development and evaluation of galaxy shape measurement algorithms for radio interferometric data
The purpose of this Thesis is to develop, test, and characterize different models attempting to tackle the problem of measurement of galaxy shapes applied in interferometric observations. Shape measurement is a tool for estimating the underlying shear due ...
EPFL2021Structured light engineering using a photonic nanojet
Toralf Scharf, Maryam Yousefi, Daniel Necesal
In this Letter, we present the photonic nanojet as a phenomenon in a structured light generator system that is implemented to modify the source focal spot size and emission angle. The optical system comprises a microlens array that is illuminated by a focu ...
OPTICAL SOC AMER2021The e-MERGE Survey (e-MERLIN Galaxy Evolution Survey): overview and survey description
Jean-Paul Richard Kneib, Cole Stewart Simpson, Mark Thomas Sargent
We present an overview and description of the e-MERGE Survey (e-MERLIN Galaxy Evolution Survey) Data Release 1 (DR1), a large program of high-resolution 1.5-GHz radio observations of the GOODS-N field comprising similar to 140 h of observations with enhanc ...
OXFORD UNIV PRESS2020High-Throughput Nanocapillary Filling Enabled by Microwave Radiation for Scanning Ion Conductance Microscopy Imaging
Aleksandra Radenovic, Georg Fantner, Vytautas Navikas, Sanjin Marion, Sebastian James Davis, Samuel Mendes Leitão
Solid state nanopores provide a highly sensitive tool for single-molecule sensing and probing nanofluidic effects in solutions. Glass nanopipettes are a cheap and robust type of solid-state nanopore produced from pulling glass capillaries with opening orif ...
