1. A method for operating a quantum computer system, comprising:
identifying an ion chain having a plurality of trapped ions;
selecting at least two non-consecutive trapped ions in the ion chain for implementing a qubit;
applying at least a first Raman beam to shuttle at least one neighbor of the at least two non-consecutive trapped ions from a ground state to a metastable state; and
applying at least a second Raman beam to one or more of the at least two non-consecutive trapped ions after shuttling the at least one neighbor to the metastable state.
