DESCRIPTION:Speakers: Guillermo Muñoz Menés\n\nQuantum computers are adv
 ancing quickly\, but solving practical problems requires higher-scale arch
 itectures and more efficient algorithms. One promising approach is to repl
 ace qubits with qudits\, quantum systems with more than two levels. Trappe
 d ions suit this approach well\, since lasers can control many internal le
 vels of each ion. Even so\, entangling operations between qudits remain ch
 allenging. In this work\, we consider a native qudit version of the Mølme
 r–Sørensen gate\, the standard entangling gate for trapped ions\, in wh
 ich several optical transitions are driven at the same time on each ion. I
 n this setup\, the presence of cross-talks on the induced AC Stark shifts 
 of each transition make gate calibration especially challenging. We presen
 t a calibration protocol that corrects these and other systematic errors u
 sing only quantities that can be measured in the experiment\, without full
  process tomography.\n\nhttps://indico.dfa.unipd.it/event/1947/
