Benchmark of transport-induced motional excitations in an 8-qubit quantum processor — •Phil Nuschke1, Rodrigo Munoz1, Teresa Meiners1, Brigitte Kaune1, and Christian Ospelkaus1,2 — 1Institut für Quantenoptik, Leibniz Universität Hannover, Welfen- garten 1, 30167 Hannover, Germany — 2Physikalisch-Technische Bundesanstalt, Bundesallee 100, 38116 Braunschweig, Germany
We present a framework to analyse the effect of transport on the motional states of ions in a trapped-ion quantum processor. By decomposing the shuttling protocol into primitive operations, we can evaluate their heating effects individually and combine results algebraically, avoiding full simulations for entire trajectories. We benchmark this method on an 8-qubit quantum processor, integrating the cost of motional operations at the compiler level.
