Bichromatic laser for quantum computing applications

A multi-frequency laser system comprising:

• a master oscillator configured to generate a master beam;
• an arm splitter configured to split the master beam into a first beam and a second beam, the first beam provided to a primary mode arm for generation of a primary mode beam and the second beam provided to a sideband mode arm for generation of a sideband mode beam;
• and
• the sideband beam arm comprising:
• a modulator configured to modulate the second beam to generate a beam comprising sidebands;
• a filter configured to select a particular sideband mode from the beam comprising sidebands to generate a selected sideband beam;
• an amplifier cavity configured to amplify the particular sideband mode and suppress other residual modes of the selected sideband mode;
• and
• an acousto-optical modulator configured to shift the frequency of each mode of an amplified selected sideband beam to generate a sideband mode beam,
• wherein the primary mode beam and sideband mode beam are provided in a coordinated manner to one or more atomic objects to enact a quantum gate.
