Leonardo Razzai

Leonardo Razzai is a PhD candidate in Physics at the University of Bologna. His research lies at the intersection of atomic physics and photonics, with a focus on the cooling and trapping of rubidium atoms inside hollow-core photonic crystal fibers. By confining light and matter in reduced geometries, he studies emerging collective quantum phenomena while developing experimental platforms with potential applications in telecomunications, also quantum.

His path into this field began with work on quantum key distribution during his Bachelor’s thesis at INO-CNR, where he implemented single-photon up-conversion techniques and characterized fiber-based time-bin encoding systems. This experience shaped his interest in bridging fundamental studies of quantum systems with their technological applications.

In his PhD, he combines advanced experimental methods in laser cooling and optical trapping with numerical modeling, aiming to advance both our understanding of light–atom interactions and the design of next-generation quantum technologies.
