Verification for quantum emulation in thermal equilibrium — •Iris Schwenk, Michael Marthaler, and Gerd Schön — Institut für Theoretische Festkörperphysik - KIT , Karlsruhe

A quantum emulator is an experimental setup that mimics an interesting physical system of some relevance for physics or applications. In order to explore the reliability of a quantum emulator we analyse a system-bath setting in thermal equilibrium. Therefore we compute the reduced density matrix of the system analytically. Applying a diagrammatic approach we get a determining equation for the reduced density matrix. Using this equation we discuss restrictions of the scalability of a quantum emulator and possibilities to avoid them.
