1. A method for stabilizing laser beams in a quantum computing system, the method comprising:
applying an array of laser beams to respective ions in an ion trap of the quantum computing system;
performing at least one separate measurement directly on each of the ions to identify fluctuations in intensity in the respective laser beams of the array of laser beams; and
adjusting the intensity of one or more of the laser beams in response to fluctuations identified from the at least one separately measurement of each of the ions.
