qiskit.quantum_info.Statevector.from_int

static Statevector.from_int(i, dims)[source]

Return a computational basis statevector.

Parameters
  • i (int) – the basis state element.

  • dims (int or tuple or list) – The subsystem dimensions of the statevector (See additional information).

Returns

The computational basis state \(|i\rangle\).

Return type

Statevector

Additional Information:

The dims kwarg can be an integer or an iterable of integers.

  • Iterable – the subsystem dimensions are the values in the list with the total number of subsystems given by the length of the list.

  • Int – the integer specifies the total dimension of the state. If it is a power of two the state will be initialized as an N-qubit state. If it is not a power of two the state will have a single d-dimensional subsystem.
