cuquantum.cutensornet.expectation_configure¶

cuquantum.cutensornet.expectation_configure(intptr_t handle, intptr_t tensor_network_expectation, int attribute, intptr_t attribute_value, size_t attribute_size)[source]¶

Configures computation of the requested tensor network state expectation value.

Parameters

handle (intptr_t) – cuTensorNet library handle.
tensor_network_expectation (intptr_t) – Tensor network state expectation value representation.
attribute (ExpectationAttribute) – Configuration attribute.
attribute_value (intptr_t) – Pointer to the configuration attribute value (type-erased).
attribute_size (size_t) – The size of the configuration attribute value.

Note

To compute the attribute size, use the itemsize of the corresponding data type, which can be queried using get_expectation_attribute_dtype().
