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…
Entanglement: Quantum or Classical?
Dilip Paneru, Eliahu Cohen, Robert Fickler +2
From its seemingly non-intuitive and puzzling nature, most evident in numerous EPR-like gedankenexperiments to its almost ubiquitous presence in quantum technologies, entanglement…
Sum rules in zone axis STEM-orbital angular momentum resolved electron magnetic chiral dichroism
Matteo Zanfrognini, Enzo Rotunno, Jan Rusz +4
In this work we derive sum rules for orbital angular momentum(OAM) resolved electron magnetic chiral dichroism (EMCD) which enable the evaluation of the strength of spin and orbita…
Design of electrostatic phase elements for sorting the orbital angular momentum of electrons
Giulio Pozzi, Vincenzo Grillo, Peng-Han Lu +3
The orbital angular momentum (OAM) sorter is a new electron optical device for measuring an electron s OAM. It is based on two phase elements, which are referred to as the unwrappe…
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…
