qiskit.quantum_info.Statevector.reset

Statevector.reset(qargs=None)[source]

Reset state or subsystems to the 0-state.

Parameters

qargs (list or None) -- subsystems to reset, if None all subsystems will be reset to their 0-state (Default: None).

Returns

the reset state.

Return type

Statevector

Additional Information:

If all subsystems are reset this will return the ground state on all subsystems. If only a some subsystems are reset this function will perform a measurement on those subsystems and evolve the subsystems so that the collapsed post-measurement states are rotated to the 0-state. The RNG seed for this sampling can be set using the seed() method.
