geqo 0.1.0

A quantum computing framework

geqo

geqo is a framework for constructing and describing quantum circuits and executing them on simulators and on quantum hardware devices.

The documentation can be found here.

Quick installation and testing

1. clone the repository: git clone https://github.com/JoSQUANTUM/geqo
2. create a virtual environment: python -m venv geqo-env
3. enable environment: source geqo-env/bin/activate
4. install geqo with all options: pip install geqo/[sympy,numpy,visualization,dev]
5. optional: run unit tests: python -m pytest geqo/tests/

geqo is also available on PyPI. To install from PyPI just create and activate an environment with steps 2 and 3 and then install geqo with pip install geqo[sympy,numpy,visualization,dev].

Running a simple example

• the example task is to get unitary of a quantum circuit for the EPR pair generation
• start Python in the environment from the steps above
• run the following commands:

from geqo.gates import Hadamard, CNOT
from geqo.core import Sequence
seq=Sequence([],["q1","q2"],[ (Hadamard(),["q1"]), (CNOT(), ["q1","q2"]) ])

from geqo.simulators import simulatorUnitarySymPy
sim=simulatorUnitarySymPy(2)
sim.apply(seq,[0,1])
sim.u

The expected result is

Matrix([
[sqrt(2)/2,         0,  sqrt(2)/2,          0],
[        0, sqrt(2)/2,          0,  sqrt(2)/2],
[        0, sqrt(2)/2,          0, -sqrt(2)/2],
[sqrt(2)/2,         0, -sqrt(2)/2,          0]])
