Qamomile to CUDA-Q Parameter Converter

This module provides functionality to convert Qamomile parameter expressions to CUDA-Q parameter expressions. It is essential for transpiling Qamomile circuits to CUDA-Q kernels, ensuring that parameterized gates are correctly translated between the two frameworks.

The main function, convert_parameter, recursively traverses Qamomile parameter expressions and converts them to equivalent CUDA-Q expressions.

Usage:

from qamomile.cudaq.parameter_converter import convert_parameter cudaq_param = convert_parameter(qamomile_param, parameter_map)

Note: This module requires both Qamomile and CUDA-Q to be installed.

Functions#

convert_parameter(→ cudaq.QuakeValue)

Convert a Qamomile parameter expression to a CUDA-Q parameter expression.

Module Contents#

convert_parameter(param: qamomile.core.circuit.ParameterExpression, parameters: dict[qamomile.core.circuit.Parameter, cudaq.QuakeValue]) → cudaq.QuakeValue#

Convert a Qamomile parameter expression to a CUDA-Q parameter expression.

This function recursively traverses the Qamomile parameter expression and converts it to an equivalent CUDA-Q parameter expression. It handles Parameters, Values, and BinaryOperators.

Parameters:

  • param (ParameterExpression) – The Qamomile parameter expression to convert.

  • parameters (dict[Parameter, cudaq.QuakeValue]) – A mapping of Qamomile Parameters to their corresponding CUDA-Q Parameters.

Returns:

The equivalent CUDA-Q parameter expression.

Return type:

cudaq.QuakeValue

Raises:

QamomileCudaqTranspileError – If an unsupported parameter type or binary operation is encountered.

Examples

>>> qamomile_param = Parameter('theta')
>>> cudaq_param = cudaq.QuakeValue("theta", cudaq.make_kernel())
>>> param_map = {qamomile_param: cudaq_param}
>>> result = convert_parameter(qamomile_param, param_map)
>>> isinstance(result, cudaq.QuakeValue)
True
