1. A device, comprising:
a plurality of first switches, wherein:
each first switch in the plurality of first switches including includes a corresponding set of two or more first channels,
wherein each first switch is configured to shift photons in the corresponding set of first channels by zero or more channels, based on first configuration information provided to the first switch; and
a plurality of second switches, each second switch of the plurality of second switches including a corresponding set of two or more second channels,
wherein:
the plurality of second switches is coupled to a plurality of output channels,
each second switch is coupled, by the corresponding set of second channels, to outputs of two or more first switches, and
each second switch is configured to shift photons in the corresponding set of second channels by zero or more channels, based on second configuration information provided to the second switch so that two or more photons are concurrently provided to two or more respective output channels of the plurality of output channels.
