- Draw a quantum gate using Qiskit. - Note - This method requires additional dependencies from - ket-lang[plot].- Install with: - pip install ket-lang[plot].- Parameters:
- gate – Quantum gate function. 
- qubits – Number of qubits. 
- args – Classical arguments to pass to the gate function. 
- qpu_size – Size of the quantum processing unit (QPU). If specified, the number of qubits will be adjusted to fit the QPU size. 
- u4_gate – Type of U4 gate to use, either “CX” or “CZ”. 
- u2_gates – Type of U2 gates to use, either “ZYZ” or “RzSx”. 
- coupling_graph – Coupling graph of the QPU, specified as a list of tuples representing connected qubits. 
- title – Title for the circuit diagram. 
- keep_order – Maintain the gate call order. 
- **kwargs – Keyword arguments to pass to the Qiskit drawer. 
 
- Returns:
- Qiskit circuit diagram of the quantum gate. 
 
- dump_matrix(gate: Callable, num_qubits: int | list[int] = 1, args=(), process: Process | None = None) list[list[complex]]¶
- Get the matrix representation of a quantum gate. - This function calculates the matrix representation of a quantum gate. - Parameters:
- gate – Quantum gate operation to obtain the matrix for. 
- num_qubits – Number of qubits. 
- args – Classical arguments to pass to the gate function. 
- process – Quantum process used to generate the matrix. 
 
- Returns:
- Matrix representation of the quantum gate.
