What is Qibo?

Qibo is an open-source full stack API for quantum simulation and quantum hardware control. Qibo aims to contribute as a community driven quantum middleware software with

1. Simplicity: agnostic design to quantum primitives.

2. Flexibility: transparent mechanism to execute code on classical and quantum hardware.

3. Community: a common place where find solutions to accelerate quantum development.

4. Documentation: describe all steps required to support new quantum devices or simulators.

5. Applications: maintain a large ecosystem of applications, quantum models and algorithms.

Components

The main components of Qibo are presented in Getting started

Key features

• 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.
