Geometrical derivation of Wigner's angle for arbitrary Lorentz transformations of massless particles
Isabella Cerutti, Petra F. Scudo
This note summarizes the physics and mathematics of Lorentz transformations for massless particles, specifically for photons. We provide a complete analytical derivation of Wigner'…

Can optimal collective measurements outperform individual measurements for non-orthogonal QKD signals?
Isabella Cerutti, Petra F. Scudo
We consider how the theory of optimal quantum measurements determines the maximum information available to the receiving party of a quantum key distribution (QKD) system employing…
