Qibo is an open-source full stack API for quantum simulation and quantum hardware control.

Some of the key features of Qibo are:

• Definition of a standard language for the construction and execution of quantum circuits with device agnostic approach to simulation and quantum hardware control based on plug and play backend drivers.
• A continuously growing code-base of quantum algorithms applications presented with examples and tutorials.
• Efficient simulation backends with GPU, multi-GPU and CPU with multi-threading support.
• Simple mechanism for the implementation of new simulation and hardware backend drivers.

Qibo documentation is available here.

A simple Quantum Fourier Transform (QFT) example to test your installation:

from qibo.models import QFT

# Create a QFT circuit with 15 qubits
circuit = QFT(15)

# Simulate final state wavefunction default initial state is |00>
final_state = circuit()

Here another example with more gates and shots simulation:

import numpy as np
from qibo import Circuit, gates

c = Circuit(2)
c.add(gates.X(0))

# Add a measurement register on both qubits
c.add(gates.M(0, 1))

# Execute the circuit with the default initial state |00>.
result = c(nshots=100)

In both cases, the simulation will run in a single device CPU or GPU in double precision complex128.
