Quantum Volume¶
Introduction¶
Quantum Volume (QV) is a method to verify device performance and a metric to quantify the computational power of a quantum device. The method is based on the paper “Validating quantum computers using randomized model circuits” (https://arxiv.org/abs/1811.12926).
This notebook gives an example for how to use the ignis.verification.quantum_volume module. This particular example shows how to run up to depth 6 quantum volume circuits and will run them using the noisy Aer simulator.

#Import general libraries (needed for functions)
import numpy as np
import matplotlib.pyplot as plt
from IPython import display
#Import Qiskit classes classes
import qiskit
from qiskit.providers.aer.noise import NoiseModel
from qiskit.providers.aer.noise.errors.standard_errors import depolarizing_error, thermal_relaxation_error
#Import the qv function.
import qiskit.ignis.verification.quantum_volume as qv
Select the Parameters of the QV Run¶
In this example we have 6 qubits Q0,Q1,Q3,Q5,Q7,Q10. We are going to look at subsets up to the full set.
[2]:
#Qubit list
qubit_lists = [[0,1,3],[0,1,3,5],[0,1,3,5,7],[0,1,3,5,7,10]]
ntrials = 50
Generate QV sequences¶
We generate the quantum volume sequences. We start with a small example (so it doesn’t take too long to run).
[3]:
qv_circs, qv_circs_nomeas = qv.qv_circuits(qubit_lists, ntrials)

#pass the first trial of the nomeas through the transpiler to illustrate the circuit
qv_circs_nomeas[0] = qiskit.compiler.transpile(qv_circs_nomeas[0], basis_gates=['u1','u2','u3','cx'])
As an example, we print the circuit corresponding to the first QV sequence. Note that the ideal circuits are run on the first n qubits (where n is the number of qubits in the subset).

Simulate the ideal circuits¶
The quantum volume method requires that we know the ideal output for each circuit, so use the statevector simulator in Aer to get the ideal result.
[6]:
#The Unitary is an identity (with a global phase)
backend = qiskit.Aer.get_backend('statevector_simulator')
ideal_results = []
for trial in range(ntrials):
print('Simulating trial %d'%trial)
ideal_results.append(qiskit.execute(qv_circs_nomeas[trial], backend=backend, optimization_level=0).result())

Next, load the ideal results into a quantum volume fitter:
[7]:
qv_fitter = qv.QVFitter(qubit_lists=qubit_lists)
qv_fitter.add_statevectors(ideal_results)
Define the noise model¶
We define a noise model for the simulator. To simulate decay, we add depolarizing error probabilities to the CNOT and U gates.
[8]:
noise_model = NoiseModel()
p1Q = 0.002
p2Q = 0.02
noise_model.add_all_qubit_quantum_error(depolarizing_error(p1Q, 1), 'u2')
noise_model.add_all_qubit_quantum_error(depolarizing_error(2*p1Q, 1), 'u3')
noise_model.add_all_qubit_quantum_error(depolarizing_error(p2Q, 2), 'cx')
#noise_model = None
Execute on Aer simulator¶
We can execute the QV sequences either using a Qiskit Aer Simulator (with some noise model) or using an IBMQ provider, and obtain a list of results, result_list.
[9]:
backend = qiskit.Aer.get_backend('qasm_simulator')
basis_gates = ['u1','u2','u3','cx'] # use U,CX for now
shots = 1024
exp_results = []
for trial in range(ntrials):
print('Running trial %d'%trial)
exp_results.append(qiskit.execute(qv_circs[trial], basis_gates=basis_gates, backend=backend, noise_model=noise_model, backend_options={'max_parallel_experiments': 0}).result())
