pecos-toolkit

Description

This project is a toolkit developed for PECOS based quantum circuit simulations of quantum error correction codes (QECCs). Currently, this project implements:

• A Steane code simulator up to circuit noise.
• Fault tolerant flag based error detection circuits.
• A fault tolerant Look-Up-Table (LUT) decoder
• A fault tolerant sequential LUT (SeqLUT) decoder.
• A fault tolerant fully connected neural network decoder.
• A fault tolerant recurrent neural network decoder.

The toolkit implements a few changes to the standard pecos QuantumCircuit, extending its features. It also offers a highly customizable error generator and a circuit runner with extended features. The repository aims to be an object oriented implementation which is in line with PECOS.

Dependencies

This package depends on the PECOS version provided by Sascha Heußen. Currently there is no public repository for this version.

Installation

To install this package follow these steps:

• Download or clone this repository
• Open the project root directory
• (Make sure to activate your virtual environment where PECOS is installed if you are using one)
• run pip install . for a regular install or pip install . -e in dev mode. The second command will ensure that you can keep developing the package without having to reinstall it.

Getting Started
