- static DensityMatrix.from_int(i, dims)¶
Return a computational basis state density matrix.
i (int) – the basis state element.
dims (int or tuple or list) – The subsystem dimensions of the statevector (See additional information).
The computational basis state \(|i\rangle\!\langle i|\).

- Additional Information:
dimskwarg 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.
