sample_state_vector(state: numpy.ndarray, indices: List[int], repetitions: int = 1) → List[List[bool]]¶
Samples repeatedly from measurements in the computational basis.
Note that this does not modify the passed in state.
- state – The multi-qubit wavefunction to be sampled. This is an array of
2 to the power of the number of qubit complex numbers, and so
state must be of size
2**integer. The state can be a vector of size
2**integeror a tensor of shape
(2, 2, ..., 2).
- indices – Which qubits are measured. The state is assumed to be supplied in big endian order. That is the xth index of v, when expressed as a bitstring, has the largest values that the 0th index.
- repetitions – The number of times to sample the state.
Measurement results with True corresponding to the
|1⟩state. The outer list is for repetitions, and the inner corresponds to measurements ordered by the input indices.
repetitionsis less than one or size of
stateis not a power of 2.
IndexError– An index from
indicesis out of range, given the number of qubits corresponding to the state.
- state – The multi-qubit wavefunction to be sampled. This is an array of 2 to the power of the number of qubit complex numbers, and so state must be of size
