Mesoscopic Description of Entanglement of Bosonic Fields and Its Open Evolution

Explore a 41-minute lecture on the mesoscopic description of entanglement in bosonic fields and their open evolution. Delve into simplified descriptions of mesoscopic systems that capture non-classical phenomena like entanglement, crucial for advancing photonic quantum computing and communication. Examine a novel approach based on boson-number correlations, allowing for the tracking of Markovian open evolution of entanglement in both non-Gaussian and Gaussian states. Discover how this method maps multi-mode bosonic field entanglement onto two-particle-like states in finite-dimensional Hilbert space, enabling intuitive use of known tools. Gain insights into examples relevant to quantum communication tasks, presented by Mgr Konrad Schlichtholz from the International Centre for Theory of Quantum Technologies at the University of Gdansk during a Wednesday colloquium at the Center for Theoretical Physics of the Polish Academy of Sciences.
