Geometric phase from Aharonov-Bohm to Pancharatnam-Berry and beyond
Eliahu Cohen, Hugo Larocque, Frederic Bouchard +3
Whenever a quantum system undergoes a cycle governed by a slow change of parameters, it acquires a phase factor: the geometric phase. Its most common formulations are known as the…
High-dimensional quantum gates using full-field spatial modes of photons
Florian Brandt, Markus Hiekkamäki, Frédéric Bouchard +2
Unitary transformations are the fundamental building blocks of gates and operations in quantum information processing allowing the complete manipulation of quantum systems in a coh…
Characterization of an underwater channel for quantum communications in the Ottawa River
Felix Hufnagel, Alicia Sit, Florence Grenapin +8
We examine the propagation of optical beams possessing different polarization states and spatial modes through the Ottawa River in Canada. A Shack-Hartmann wavefront sensor is used…
Full-field mode sorter using two optimized phase transformations for high-dimensional quantum cryptography
Robert Fickler, Frédéric Bouchard, Enno Giese +3
High-dimensional encoding schemes have emerged as a novel way to perform quantum information tasks. For high dimensionality, temporal and transverse spatial modes of photons are th…
Overcoming Noise in Entanglement Distribution
Sebastian Ecker, Frédéric Bouchard, Lukas Bulla +8
Noise can be considered the natural enemy of quantum information. An often implied benefit of high-dimensional entanglement is its increased resilience to noise. However, manifesti…
Multi-twist polarization ribbon topologies in highly-confined optical fields
Thomas Bauer, Peter Banzer, Frédéric Bouchard +6
Electromagnetic plane waves, solutions to Maxwell's equations, are said to be `transverse' in vacuum. Namely, the waves' oscillatory electric and magnetic fields are confined withi…
