# qiskit.providers.models.GateConfig
<Class id="qiskit.providers.models.GateConfig" isDedicatedPage={true} github="https://github.com/qiskit/qiskit/tree/stable/0.17/qiskit/providers/models/backendconfiguration.py" signature="GateConfig(name, parameters, qasm_def, coupling_map=None, latency_map=None, conditional=None, description=None)" modifiers="class">
Class representing a Gate Configuration
### name
<Attribute id="qiskit.providers.models.GateConfig.name">
the gate name as it will be referred to in Qasm.
</Attribute>
### parameters
<Attribute id="qiskit.providers.models.GateConfig.parameters">
variable names for the gate parameters (if any).
</Attribute>
### qasm\_def
<Attribute id="qiskit.providers.models.GateConfig.qasm_def">
definition of this gate in terms of Qasm primitives U and CX.
</Attribute>
Initialize a GateConfig object
**Parameters**
* **name** (*str*) the gate name as it will be referred to in Qasm.
* **parameters** (*list*) variable names for the gate parameters (if any) as a list of strings.
* **qasm\_def** (*str*) definition of this gate in terms of Qasm primitives U and CX.
* **coupling\_map** (*list*) An optional coupling map for the gate. In the form of a list of lists of integers representing the qubit groupings which are coupled by this gate.
* **latency\_map** (*list*) An optional map of latency for the gate. In the the form of a list of lists of integers of either 0 or 1 representing an array of dimension len(coupling\_map) X n\_registers that specifies the register latency (1: fast, 0: slow) conditional operations on the gate
* **conditional** (*bool*) Optionally specify whether this gate supports conditional operations (true/false). If this is not specified, then the gate inherits the conditional property of the backend.
* **description** (*str*) Description of the gate operation
### \_\_init\_\_
<Function id="qiskit.providers.models.GateConfig.__init__" signature="__init__(name, parameters, qasm_def, coupling_map=None, latency_map=None, conditional=None, description=None)">
Initialize a GateConfig object
**Parameters**
* **name** (*str*) the gate name as it will be referred to in Qasm.
* **parameters** (*list*) variable names for the gate parameters (if any) as a list of strings.
* **qasm\_def** (*str*) definition of this gate in terms of Qasm primitives U and CX.
* **coupling\_map** (*list*) An optional coupling map for the gate. In the form of a list of lists of integers representing the qubit groupings which are coupled by this gate.
* **latency\_map** (*list*) An optional map of latency for the gate. In the the form of a list of lists of integers of either 0 or 1 representing an array of dimension len(coupling\_map) X n\_registers that specifies the register latency (1: fast, 0: slow) conditional operations on the gate
* **conditional** (*bool*) Optionally specify whether this gate supports conditional operations (true/false). If this is not specified, then the gate inherits the conditional property of the backend.
* **description** (*str*) Description of the gate operation
