Prepares a Pauli expansion view for quantum operator application.

Parameters:

  • handle (intptr_t) – Library handle.

  • view_in (intptr_t) – Pauli expansion view to apply a quantum operator to.

  • quantum_operator (intptr_t) – Quantum operator to be applied.

  • make_sorted (int32_t) – Whether or not the output expansion is required to be sorted.

  • keep_duplicates (int32_t) – Whether or not the output expansion is allowed to contain duplicates.

  • num_truncation_strategies (int32_t) – Number of Pauli expansion truncation strategies.

  • truncation_strategies (object) –

    Pauli expansion truncation strategies. It can be:

    • an int as the pointer address to the array, or

    • a Python sequence of cupaulipropTruncationStrategy_t.

  • max_workspace_size (int64_t) – Maximum workspace size limit in bytes.

  • workspace (intptr_t) – Workspace descriptor with the required workspace buffer size.

Returns:

  • int64_t: Required size (in bytes) of the X and Z bits output buffer.

  • int64_t: Required size (in bytes) of the coefficients output buffer.

Return type:

A 2-tuple containing
