Convergence Rates for the Trotter Splitting for Unbounded Operators

Simon Becker, Niklas Galke, Robert Salzmann +1

We study convergence rates of the Trotter splitting $e^{A + L} = lim_{n \to \infty} (e^{L / n} e^{A / n})^{n}$ in the strong operator topology. In the first part, we use complex interpola…

Embezzlement of entanglement, quantum fields, and the classification of von Neumann algebras

Lauritz van Luijk, Alexander Stottmeister, Reinhard F. Werner +1

We study the quantum information theoretic task of embezzlement of entanglement in the setting of von Neumann algebras. Given a shared entangled resource state, this task asks to p…
