cuquantum.bindings.cupauliprop.pauli_expansion_view_compute_trace_with_expansion_view( intptr_t handle, intptr_t view1, intptr_t view2, int32_t take_adjoint1, intptr_t trace_significand, intptr_t trace_exponent, intptr_t workspace, intptr_t stream, )[source]#

Computes the trace of the product of two Pauli expansion views.

Parameters:

handle (intptr_t) – Library handle.
view1 (intptr_t) – First Pauli expansion view.
view2 (intptr_t) – Second Pauli expansion view.
take_adjoint1 (int32_t) – Whether or not the adjoint of the first view is taken. True (!= 0) if the adjoint is taken, false (0) otherwise.
trace_significand (intptr_t) – Pointer to CPU-accessible memory where the trace’s significand will be written. The numerical type must match the data type of the views’ coefficients.
trace_exponent (intptr_t) – Pointer to CPU-accessible memory where the trace’s exponent will be stored. The numerical type is always double.
workspace (intptr_t) – Allocated workspace descriptor.
stream (intptr_t) – CUDA stream to be used for the operation.
