qiskit.parameter_converter

Qamomile to Qiskit Parameter Converter

This module provides functionality to convert Qamomile parameter expressions to Qiskit parameter expressions. It is essential for transpiling Qamomile circuits to Qiskit circuits, 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 Qiskit expressions.

Usage:

from qamomile.qiskit.parameter_converter import convert_parameter qiskit_param = convert_parameter(qamomile_param, parameter_map)

Note: This module requires both Qamomile and Qiskit to be installed.

Functions

convert_parameter(→ qiskit.circuit.ParameterExpression)

Convert a Qamomile parameter expression to a Qiskit parameter expression.

Module Contents

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

Convert a Qamomile parameter expression to a Qiskit parameter expression.

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

Parameters:

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

• parameters (dict[Parameter, qiskit.circuit.Parameter]) – A mapping of Qamomile Parameters to their corresponding Qiskit Parameters.

Returns:

The equivalent Qiskit parameter expression.

Return type:

qiskit.circuit.ParameterExpression

Raises:

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

Examples

>>> qamomile_param = Parameter('theta')
>>> qiskit_param = qiskit.circuit.Parameter('theta')
>>> param_map = {qamomile_param: qiskit_param}
>>> result = convert_parameter(qamomile_param, param_map)
>>> isinstance(result, qiskit.circuit.Parameter)
True
