Significant progress has been made in establishing limits on quantum transport in closed systems, but extensions to open many-body systems remain scarce. We develop the general optimal transport theory and find the maximal speed of macroscopic particle transport in dissipative long-range bosonic systems. This work was featured by Kyoto University’s Yukawa Institute for Theoretical Physics (YITP) and Clear Sky Science.
