Methods and apparatuses for cross-talk mitigation

A non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors of a quantum information processing (QIP) system, cause the one or more processors to:

• identify an ion chain having a plurality of trapped ions;
• select at least two non-consecutive trapped ions in the ion chain for implementing a qubit;
• cause a first light source to apply 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
• cause a second light source to apply 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.

A quantum information processing (QIP) system, comprising:

• a controller configured to:
• identify an ion chain having a plurality of trapped ions;
• select at least two non-consecutive trapped ions in the ion chain for implementing a qubit;
• a first light source configured to apply 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
• a second light source configured to apply 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.
