Reset state or subsystems to the 0-state.
qargs (list or None) -- subsystems to reset, if None all subsystems will be reset to their 0-state (Default: None).
the reset state.
- Return type
- Additional Information:
If all subsystems are reset this will return the ground state on all subsystems.

The RNG seed for this sampling can be set using the
