Path Operators

This is a list of the path operators available in Qmod for accessing elements and sub-arrays of arrays inside quantum expressions. Functions:

Name	Description
`python_value_to_qmod_object`	Translate a Python classical value into a QMod object.
`subscript`	Return the element of `array` at position `index` in an expression.
`slice_`	Return the `array[start:stop]` sub-array in an expression.

python_value_to_qmod_object

python_value_to_qmod_object(
value: Any,
qmodule: ModelStateContainer
) -> Any

Translate a Python classical value into a QMod object. numpy values are normalized to native Python, and dataclasses (which are always classical structs in QMod) become QmodStructInstances with their declaration registered on qmodule. The result is a QMod object from which both an expression string (via qmod_val_to_expr_str) and a classical type (via infer_classical_type) can be derived. Parameters:

Name	Type	Description	Default
`value`	`Any`		required
`qmodule`	`ModelStateContainer`		required

subscript

subscript(
array: list | CArray | np.ndarray,
index: Any
) -> Any

Return the element of array at position index in an expression. This is the expression-level form of the array[index] indexing operator. Parameters:

Name	Type	Description	Default
`array`	`list \| CArray \| np.ndarray`	The array to index into. May be a Python list, a quantum-variable concatenation, a `CArray` parameter, or a numpy array.	required
`index`	`Any`	The position to read, as a classical expression.	required

slice_

slice_(
array: list | CArray | np.ndarray,
start: Any,
stop: Any
) -> Any

Return the array[start:stop] sub-array in an expression. This is the expression-level form of the array[start:stop] slicing operator. Parameters:

Name	Type	Description	Default
`array`	`list \| CArray \| np.ndarray`	The array to slice. May be a Python list, a quantum-variable concatenation, a `CArray` parameter, or a numpy array.	required
`start`	`Any`	The index of the first element of the slice, inclusive.	required
`stop`	`Any`	The index one past the last element of the slice, exclusive.	required
options:
show_source: false
show_if_no_docstring: false
