+Extracting the greatest performance from quantum hardware requires real-time pulse-level
+instructions. Pulse answers that need: it enables the quantum physicist *user* to specify the
+exact time dynamics of an experiment. It is especially powerful for error mitigation techniques.
+
+The input is given as arbitrary, time-ordered signals (see: :ref:`pulse-commands`) scheduled in
+parallel over multiple virtual hardware or simulator resources (see: :ref:`pulse-channels`). The
+system also allows the user to recover the time dynamics of the measured output.
+
+This is sufficient to allow the quantum physicist to explore and correct for noise in a quantum
+system.

+Pulse is meant to be agnostic to the underlying hardware implementation, while still allowing
+low-level control. Therefore, our signal channels are  *virtual* hardware channels. The backend
+which executes our programs is responsible for mapping these virtual channels to the proper
+physical channel within the quantum control hardware.
+
+Channels are characterized by their type and their index. See each channel type below to learn more.
