Methods and apparatuses for rf amplifier power transient mitigation with idle tones

An acousto-optic system in a quantum information processing (QIP) system, comprising:

• a radio frequency (RF) driver configured to:
• apply a first RF tone, at a first RF power and a first RF frequency, to modulate at least one laser beam into a first modulated laser beam via an acousto-optic device, and
• applying a second RF tone, at a second RF power and at a second RF frequency different than the first RF frequency, to modulate the at least one laser beam into a second modulated laser beam via the acousto-optic device;
• and
• the acousto-optic device configured to:
• provide the first modulated laser beam to at least one target ion of an ion chain in the QIP system, and
• provide the second modulated laser beam to one or more ions in the ion chain, wherein the second modulated laser beam does not change any quantum state of the one or more ions.

A non-transitory computer readable medium comprising instructions that, when executed by a processor of a quantum information processing (QIP) system, cause the processor to:

• cause a radio frequency (RF) driver to apply a first RF tone, at a first RF power and a first RF frequency, to modulate at least one laser beam into a first modulated laser beam via an acousto-optic device;
• cause the acousto-optic device to provide the first modulated laser beam to at least one target ion of an ion chain in the QIP system;
• cause a RF driver to apply a second RF tone, at a second RF power and at a second RF frequency different than the first RF frequency, to modulate the at least one laser beam into a second modulated laser beam via the acousto-optic device;
• and
• cause the acousto-optic device to provide the second modulated laser beam to one or more ions in the ion chain, wherein the second modulated laser beam does not change any quantum state of the one or more ions.
