Nondestructive Measurement of Orbital Angular Momentum for an Electron Beam
Hugo Larocque, Frédéric Bouchard, Vincenzo Grillo +6
Free electrons with a helical phase front, referred to as "twisted" electrons, possess an orbital angular momentum (OAM) and, hence, a quantized magnetic dipole moment along their…
Reply to comment on "Observation of subluminal twisted light in vacuum"
Frédéric Bouchard, Robert W. Boyd, Ebrahim Karimi
Recently, we showed experimentally that light carrying orbital angular momentum experiences a slight subluminality under free-space propagation [1]. We thank Saari [2] for pointing…
Measuring an electron beam's orbital angular momentum spectrum
incenzo Grillo, Amir H. Tavabi, Federico Venturi +12
Quantum complementarity states that particles, e.g. electrons, can exhibit wave-like properties such as diffraction and interference upon propagation. \textit{Electron waves} defin…
High-dimensional quantum cloning and applications to quantum hacking
Frédéric Bouchard, Robert Fickler, Robert W Boyd +1
Attempts at cloning a quantum system result in the introduction of imperfections in the state of the copies. This is a consequence of the no-cloning theorem, which is a fundamental…
Optical spin-to-orbital angular momentum conversion in ultra-thin metasurfaces with arbitrary topological charges
Frédéric Bouchard, Israel De Leon, Sebastian A. Schulz +3
Orbital angular momentum associated with the helical phase-front of optical beams provides an unbounded \qo{space} for both classical and quantum communications. Among the differen…
