Circuit Library
qiskit.circuit.library
The circuit library is a collection of well-studied and valuable circuits, directives, and gates. We call them valuable for different reasons, for instance they can serve as building blocks for algorithms or they are circuits that we think are hard to simulate classically.
Each element can be plugged into a circuit using the QuantumCircuit.append() method and so the circuit library allows users to program at higher levels of abstraction. For example, to append a multi-controlled CNOT:
from qiskit.circuit.library import MCXGate
gate = MCXGate(4)
from qiskit import QuantumCircuit
circuit = QuantumCircuit(5)
circuit.append(gate, [0, 1, 4, 2, 3])
circuit.draw('mpl')
The library is organized in several sections.
Standard gates
These operations are reversible unitary gates and they all subclass Gate. As a consequence, they all have the methods to_matrix(), power(), and control(), which we can generally only apply to unitary operations.
For example:
from qiskit.circuit.library import XGate
gate = XGate()
print(gate.to_matrix()) # X gate
print(gate.power(1/2).to_matrix()) # √X gate
print(gate.control(1).to_matrix()) # CX (controlled X) gate[[0.+0.j 1.+0.j]
[1.+0.j 0.+0.j]]
[[0.5+0.5j 0.5-0.5j]
[0.5-0.5j 0.5+0.5j]]
[[1.+0.j 0.+0.j 0.+0.j 0.+0.j]
[0.+0.j 0.+0.j 0.+0.j 1.+0.j]
[0.+0.j 0.+0.j 1.+0.j 0.+0.j]

The circuit consists of a column of Hadamard gates, a column of powers of T gates, a sequence of powers of CS gates (up to of them), and a final column of Hadamard gates, as introduced in [1].
The circuit is parameterized by an interactions matrix. The powers of each T gate are given by the diagonal elements of the interactions matrix. The powers of the CS gates are given by the upper triangle of the interactions matrix.

from qiskit.quantum_info import Operator
import numpy as np
template = template_nct_4b_1()
identity = np.identity(2 ** len(template.qubits), dtype=complex)
data = Operator(template).data
