Classification: CPC G | IPC G

Claim 0:
1. A network for synchronizing a plurality of digital-to-analog converter (DAC) cards in a quantum information processing (QIP) system, the network comprising:
the plurality of DAC cards that each include:
a clock divider/replicator device having an input SYNC pin;
a digital logic component; and
one or more DAC components that are each configured to convert a digital signal from the digital logic component to an analog signal as an output that is applied to an acousto-optic modulator to control one or more optical beams for a separate qubit of the QIP system;

a first distribution network to provide a clock signal to the clock divider/replicator device in each of the plurality of DAC cards; and
a second distribution network to provide a start signal to the respective digital logic component of each of the plurality of DAC cards,
wherein for each of the plurality of DAC cards, the start signal is used by the digital logic component in the DAC card to assert the input SYNC pin of the clock divider/replicator device of the DAC card in response to the start signal being asserted unless the start signal is masked by the digital logic component.
