Symmetry based gate design — •Kaloyan Zlatanov and Nikolay Vitanov — Department of Physics, St. Kliment Ohridski University of Sofia, 5 James Bourchier Boulevard, 1164 Sofia, Bulgaria

One of the main goals of contemporary quantum information is to design faster and more robust gates. We explore a Hamiltonian based approach to tackle this problem in which we design an interaction that yields a specific symmetry that allows the reduction of the system to two and three-level sub-systems in which various control techniques like adiabatic excitation, composite pulses or shaped pulses can be implemented. We illustrate this approach with examples in magnetic systems with Dzyaloshinskii-Moriya interaction as well as in ions for the improvment of the Molmer-Sorensen gate.
