create_operator_term#

cuquantum.bindings.cudensitymat.create_operator_term( intptr_t handle, int32_t num_space_modes, space_mode_extents, ) → intptr_t[source]#

Creates an empty operator term which is going to be a sum of products of either elementary tensor operators or full matrix operators. Each individual elementary tensor operator within a product acts on a subset of space modes, either from the left or from the right (for each mode). Each full matrix operator within a product acts on all space modes, either from the left or from the right (for all modes).

Parameters:

handle (intptr_t) – Library handle.
num_space_modes (int32_t) – Number of modes (quantum degrees of freedom) defining the primary/dual tensor product space in which the operator term will act.
space_mode_extents (object) –
Extents of the modes (quantum degrees of freedom) defining the primary/dual tensor product space in which the operator term will act. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int64_t.

Returns:

Operator term.

Return type:

intptr_t
