Detailed Description

Represents a quantum gate in a quantum circuit.

This class extends the Relation class to model quantum gates. It includes various properties specific to quantum gates, such as gate size, fidelity, and unitary matrix. The class also handles the coupling map and additional properties related to quantum gate operations. QuantumGate objects can represent both single- and multi-qubit gates, and are used to describe the logical operations that can be performed on a quantum backend.
