Snapshot channels are used to specify instructions for simulators.
Create new snapshot channel.
Return the index of this channel. The index is a label for a control signal line typically mapped trivially to a qubit index. For instance,
DriveChannel(0) labels the signal line driving the qubit labeled with index 0.
Return the shorthand alias for this channel, which is based on its type and index.
Parameters which determine the channel index.
str | None
A shorthand string prefix for characterizing the channel type.
Return True iff the channel is parameterized.
