Note that this does not modify the passed in state.

state_vector The multi-qubit state vector 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_vector can be a vector of size 2**integer or a tensor of shape (2, 2, ..., 2).
indices Which qubits are measured. The state_vector is assumed to be supplied in big endian order. That is the xth index of v, when expressed as a bitstring, has its largest values in the 0th index.
qid_shape The qid shape of the state_vector. Specify this argument when using qudits.
repetitions The number of times to sample.
seed A seed for the pseudorandom number generator.

Measurement results with True corresponding to the |1⟩ state. The outer list is for repetitions, and the inner corresponds to measurements ordered by the supplied qubits. These lists are wrapped as an numpy ndarray.

ValueError repetitions is less than one or size of state_vector is not a power of 2.
IndexError An index from indices is out of range, given the number of qubits corresponding to the state.
