On Phase-Space Representations of Spin Systems and Their Relations to Infinite-Dimensional Quantum States — •Bálint Koczor1, Robert Zeier1, Steffen J. Glaser1, Frederik vom Ende1, and Maurice A. de Gosson2 — 1Technische Universität München, Garching, Germany — 2University of Vienna, Vienna, Austria
Classical phase spaces have been widely applied in physics, engineering, economics or biology.
I will give an overview of our recent works considering phase spaces of quantum systems, which have become a powerful tool for describing, analyzing, and tomographically reconstructing quantum states. We provide a complete phase-space description of (coupled) spin systems including their time evolution, tomography, large-spin approximations and their infinite-dimensional limit, which recovers the well-known case of quantum optics.
Finally, Born-Jordan distributions of infinite-dimensional quantum systems are discussed. Refer to the recent preprints arXiv:1808.02697 and arXiv:1811.05872.
