High-Dimensional Intra-City Quantum Cryptography with Structured Photons
Alicia Sit, Frédéric Bouchard, Robert Fickler +11
Quantum key distribution (QKD) promises information-theoretically secure communication, and is already on the verge of commercialization. Thus far, different QKD protocols have bee…
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…
Quantum metrology at the limit with extremal Majorana constellations
F. Bouchard, P. de la Hoz, G. Bjork +8
Quantum metrology allows for a tremendous boost in the accuracy of measurement of diverse physical parameters. The estimation of a rotation constitutes a remarkable example of this…
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…
Arbitrary optical wavefront shaping via spin-to-orbit coupling
Hugo Larocque, Jérémie Gagnon-Bischoff, Frédéric Bouchard +4
Converting spin angular momentum to orbital angular momentum has been shown to be a practical and efficient method for generating optical beams carrying orbital angular momentum an…
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…
