Learn to simulate Gaussian quantum information systems using the Gabs.jl library in this 26-minute conference talk from JuliaCon Global 2025. Explore how quantum harmonic oscillators in phase space representation can be efficiently characterized through low-order statistical moments when their characteristic function is Gaussian, enabling computationally tractable simulations of important quantum processes. Discover the key features of Gabs.jl including symbolic representations of quantum states, translations between phase space and state-vector formalisms, symplectic analysis methods for studying quantum transformations, and techniques for simulating slightly non-Gaussian quantum states. Understand how Gaussian quantum information, while not providing quantum advantage, serves as fundamental building blocks for quantum hardware design and protocol development, making this library valuable for researchers working on quantum system simulation and analysis.
