qiskit.quantum_info.Statevector.measure

Statevector.measure(qargs=None)

Measure subsystems and return outcome and post-measure state.

Note that this function uses the QuantumStates internal random number generator for sampling the measurement outcome. The RNG seed can be set using the seed() method.

Parameter

qargs (list or None) – subsystems to sample measurements for, if None sample measurement of all subsystems (Default: None).

Rückgabe

the pair (outcome, state) where outcome is the

measurement outcome string label, and state is the collapsed post-measurement state for the corresponding outcome.

Rückgabetyp

tuple
