1. A system for optically modulating a plurality of optical channels, the system comprising:
a power delivery module adapted to convert a coherent light beam into a plurality of optical channels;
at least one optical modulator, optically coupled to the power delivery module, the at least one optical modulator adapted to optically modulate each of the plurality of the optical channels;
a vacuum chamber having a trapping plane therein, the vacuum chamber adapted to generate an addressable array of trapped particles at the trapping plane, wherein each of the plurality of optical channels is optically coupled to at least one of the trapped particles of the addressable array; and
wherein the at least one optical modulator comprises a plurality of electro-optically controlled Mach-Zehnder Interferometers (MZI), each of the plurality of the MZIs adapted to modulate one of the optical channels.
