class qupulse.expressions.protocol.Expression(*args, **kwargs)

Bases: Hashable, Protocol

This protocol defines how Expressions are allowed to be used in qupulse.

evaluate_in_scope(scope: Mapping) → Union[numbers.Real, numpy.ndarray]

Evaluate the expression by taking the variables from the given scope (typically of type Scope, but it can be any mapping.) :param scope:

Returns:

evaluate_symbolic(substitutions: Mapping[str, Any]) → qupulse.expressions.protocol.Expression

Substitute a part of the expression for another

evaluate_time_dependent(scope: Mapping) → Union[qupulse.expressions.protocol.Expression, numbers.Real, numpy.ndarray]

Evaluate to a time dependent expression or a constant.

get_serialization_data()

classmethod make(expression_or_dict, numpy_evaluation=None) → qupulse.expressions.protocol.Expression

Backward compatible expression generation to allow creation from dict.

property underlying_expression: Any

Return some internal unspecified representation

property variables: Sequence[str]

Get all free variables in the expression.

Returns

A collection of all free variables occurring in the expression.
