Compressed sensing of twisted photons
F. Bouchard, D. Koutny, F. Hufnagel +8
The ability to completely characterize the state of a quantum system is an essential element for the emerging quantum technologies. Here, we present a compressed-sensing inspired m…
Adaptive compressive tomography with no a priori information
D. Ahn, Y. S. Teo, H. Jeong +8
Quantum state tomography is both a crucial component in the field of quantum information and computation, and a formidable task that requires an incogitably large number of measure…
Orbital angular momentum and energy loss characterization of plasmonic excitations in metallic nanostructures in TEM
Matteo Zanfrognini, Enzo Rotunno, Stefano Frabboni +4
Recently, a new device to measure the Orbital Angular Momentum (OAM) electronic spectrum after elastic/inelastic scattering in a transmission electron microscope has been introduce…
Spin constrained orbital angular momentum control in high-harmonic generation
F. Kong, C. Zhang, H. Larocque +7
The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscop…
Structured Quantum Projectiles
Hugo Larocque, Robert Fickler, Eliahu Cohen +4
Matter wave interferometry is becoming an increasingly important technique in quantum metrology. However, unlike its photonic counterpart, this technique relies on the interference…
Generation of electron vortices using non-exact electric fields
Amir H. Tavabi, Hugo Larocque, Peng-Han Lu +5
Vortices in electron beams can manifest several types of topological phenomena, such as the formation of exotic structures or interactions with topologically structured electromagn…
