matrix

TimeEvolOperator.matrix(shot='all', t_idx='all', basis='product', frame='lab', in_qubit_subspace=False, remove_virtual_phase=False)

Return the time evolution operator in a specific basis and frame.

Parameters:

  • shot (str | int | List[int]) – Specify the shot by its index or indices, or use 'all'.

  • t_idx (str | int | List[int]) – Specify the time by its index or indices, or use 'all'.

  • basis (str) – Specify the basis, must be either 'product' or 'eigen'.

  • frame (str) – Specify the frame, must be either 'lab' or 'rotating'.

  • in_qubit_subspace (bool) – If True, operator is projected to qubit subspace.

  • remove_virtual_phase (bool) – If True, virtual z-phases are transformed out from the operator.

Return type:

ndarray | Array

Returns:

Time evolution operators for shots and time points. Array of shape (n_shots, n_times, dim, dim).

Hint

Use it, for example, as:

result.time_evol_operator.matrix(shot=0, t_idx=[0,-1], basis='eigen', frame='rotating')
