Universal recoverability of quantum states in tracial von-Neumann algebras
arXiv:2512.08418
Abstract
In this paper, we discuss a refinement of quantum data processing inequality for the sandwiched quasi-relative entropy on a tracial von-Neumann algebra. The main result is a universal recoverability bound with the Petz recovery map, which was previously obtained in the finite dimensional setup.
