1. A method for performing an echo sequence in a quantum information processing (QIP) system, comprising:
applying a first global optical beam to a plurality of dual space single species (DSSS) trapped ions to transition the plurality of DSSS trapped ions from a first state in a first manifold to a first state in a second manifold; and
applying, at a time after applying the first global optical beam, a second global optical beam to the plurality of DSSS trapped ions to transition:
from the first state in the second manifold to the first state in the first manifold; and
from a second state in the first manifold to a second state in the second manifold.
