# cirq.CircuitDiagramInfo¶

class cirq.CircuitDiagramInfo(wire_symbols: Iterable[str], exponent: Any = 1, connected: bool = True, exponent_qubit_index: Optional[int] = None, auto_exponent_parens: bool = True)[source]

Describes how to draw an operation in a circuit diagram.

__init__(wire_symbols: Iterable[str], exponent: Any = 1, connected: bool = True, exponent_qubit_index: Optional[int] = None, auto_exponent_parens: bool = True) → None[source]
Parameters
• wire_symbols – The symbols that should be shown on the qubits affected by this operation. Must match the number of qubits that the operation is applied to.

• exponent – An optional convenience value that will be appended onto an operation’s final gate symbol with a caret in front (unless it’s equal to 1). For example, the square root of X gate has a text diagram exponent of 0.5 and symbol of ‘X’ so it is drawn as ‘X^0.5’.

• connected – Whether or not to draw a line connecting the qubits.

• exponent_qubit_index – The qubit to put the exponent on. (The k’th qubit is the k’th target of the gate.) Defaults to the bottom qubit in the diagram.

• auto_exponent_parens – When this is True, diagram making code will add parentheses around exponents whose contents could look ambiguous (e.g. if the exponent contains a dash character that could be mistaken for an identity wire). Defaults to True.
