Qiskit Aer

LicenseBuild Status

Qiskit is an open-source framework for working with noisy intermediate-scale quantum computers (NISQ) at the level of pulses, circuits, and algorithms.

Qiskit is made up of elements that each work together to enable quantum computing. This element is Aer, which provides high-performance quantum computing simulators with realistic noise models.

Installation

We encourage installing Qiskit via the PIP tool (a python package manager), which installs all Qiskit elements, including this one.

pip install qiskit

PIP will handle all dependencies automatically for us and you will always install the latest (and well-tested) version.

To install from source, follow the instructions in the contribution guidelines.

Simulating your first quantum program with Qiskit Aer

Now that you have Qiskit Aer installed, you can start simulating quantum circuits with noise. Here is a basic example:

$ python

from qiskit import QuantumRegister, ClassicalRegister, QuantumCircuit, execute
from qiskit import Aer, IBMQ  # import the Aer and IBMQ providers
from qiskit.providers.aer import noise  # import Aer noise models

# Choose a real device to simulate
IBMQ.load_accounts()
device = IBMQ.get_backend('ibmq_16_melbourne')
properties = device.properties()
coupling_map = device.configuration().coupling_map

# Generate an Aer noise model for device
noise_model = noise.device.basic_device_noise_model(properties)
basis_gates = noise_model.basis_gates

# Generate a quantum circuit
q = QuantumRegister(2)
c = ClassicalRegister(2)
qc = QuantumCircuit(q, c)

qc.h(q[0])
qc.cx(q[0], q[1])
qc.measure(q, c)

# Perform noisy simulation
backend = Aer.get_backend('qasm_simulator')
job_sim = execute(qc, backend,
                  coupling_map=coupling_map,
                  noise_model=noise_model,
                  basis_gates=basis_gates)
sim_result = job_sim.result()

print(sim_result.get_counts(qc))
{'11': 412, '00': 379, '10': 117, '01': 116}
