cuquantum.bindings.cudensitymat.create_operator_action

cuquantum.bindings.cudensitymat.create_operator_action(intptr_t handle, int32_t num_operators, operators) → intptr_t[source]

Creates an action descriptor for one or more operators, thus defining an aggregate action of the operator(s) on a set of input quantum states compliant with the operator domains, where all input quantum states can also be batched.

Parameters

  • handle (intptr_t) – Library handle.

  • num_operators (int32_t) – Number of operators involved (number of operator-state products).

  • operators (object) –

    Constituting operator(s) with the same domain of action. Some of the operators may be set to NULL to represent zero action on a specific input quantum state. It can be:

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

    • a Python sequence of ints (as pointer addresses).

Returns

Operator action.

Return type

intptr_t
