BooleanExpression

class BooleanExpression(expression, name=None)

Bases: qiskit.circuit.classicalfunction.classical_element.ClassicalElement

The Boolean Expression gate.

Parameters

• expression (str) – The logical expression string.

• name (str) – Optional. Instruction gate name. Otherwise part of the expression is going to be used.

Methods

add_decomposition	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
assemble	Assemble a QasmQobjInstruction
broadcast_arguments	Validation and handling of the arguments and its relationship.
c_if	Add classical condition on register or cbit classical and value val.
control	Return controlled version of gate.
copy	Copy of the instruction.
from_dimacs_file	Create a BooleanExpression from the string in the DIMACS format.
inverse	Invert this instruction.
is_parameterized	Return True .IFF.
mirror	DEPRECATED: use instruction.reverse_ops().
power	Creates a unitary gate as gate^exponent.
qasm	Return a default OpenQASM string for the instruction.
repeat	Creates an instruction with gate repeated n amount of times.
reverse_ops	For a composite instruction, reverse the order of sub-instructions.
simulate	Evaluate the expression on a bitstring.
soft_compare	Soft comparison between gates.
synth	Synthesis the logic network into a QuantumCircuit.
to_matrix	Return a Numpy.array for the gate unitary matrix.
validate_parameter	Gate parameters should be int, float, or ParameterExpression
